Not so long ago, various food packaging and disposable plastic dishes in Russia were rare. Almost all of us remember the time when the products in the stores wrapped in a dense packaging paper - gray or brown.
There was no polyethylene film: the paper was wrapped in sausage, butter and cheese, fish, and even those products that are not intended for this - for example, marine cappist.
Then it seemed to everyone that it was normal, and today we consider the abundance of various food packages, packages, plastic containers, dishes and other containers. Plastic tableware today is in every home, at least in small quantities. For example, before the picnic, ordinary dishes were taken with you - porcelain, metal, glass, and then we were taken home to wash, as follows. Of course, it is significantly overshadowed by rest, and especially for women - the owners of the house.
Disposable tableware
Disposable dishes eliminates us from many tedious troubles and frees time, makes life and life easier and easier. She itself is light and comfortable, quite durable, if you compare with porcelain and glass, and most importantly - it does not need to be washed.
Disposable dishes appeared in the United States, at the beginning of the 20th century. First began to produce paper cups, and then another dishes - plates, spoons, forks, knives. Since the end of the 50s of the last century, mass production of disposable dishes were launched, and instead of paper, polymer materials began to use more and more often. Currently, many manufacturers are again inclined towards paper dishes, as it is safer and does not have toxic properties.
In our country, the first disposable dishes were also paper cups, but their appearance and quality left much to be desired: in order to somehow drink coffee, I had to insert one cup in another - otherwise it was possible to burn.
In the USSR, there were almost no fast food enterprises, so one-time dishes were not in demand. And only in the mid-90s in Russia began to produce paper and plastic disposable utensils, not inferior to the quality of American and European. Today, the basic requirements for one-time dishes are quality, safety and consumer properties.
Safety of disposable utensils
Recently, all the safety of one-time dishes began to be interested - more precisely, the material from which it is made. Opinions about this are directly opposite, and consumers are difficult to figure out how much to treat this blessing of civilization.
Buying disposable dishes, you need to clearly imagine, for what you will use it. Types of disposable tableware today have already been a lot.
Only to the kitchen and dining room and accessories include plates, cups and glasses, cutlery, cans and flasks, water bottles, products for storage products, containers for sweets and even disposable wrappers, tablecloths and napkins.
One would use one-time dishes at least several times in his life - of course, excluding the inhabitants of those regions of the planet, in which civilization has not yet reached - maybe fortunately.
At the same time, not all people have an idea of \u200b\u200bthe peculiarities of a particular type of dishes.
So, do not everyone knows that for hot drinks are not suitable for any cups: Polystyrene cups are not suitable for this - they do not withstand high temperatures and distinguish toxins in tea or coffee.
Hot drinks are best drinking from polypropylene cups - they are more stable, but alcohol cannot be poured into neither into anyone - so you can damage the liver and kidneys, as well as worsen vision.
Plastic dishes
Plastics is a material from which it is easy to make items and things of any form, especially dishes - today can be seen in many stores. Plastic things are used by all, but the problem of their disposal is very acute. Plastic does not decompose, it cannot be burned (with rare exception), and the discharged plastic objects turn the streets of most cities in the garbage, especially if there are not enough garbered and janitors.
Plastics is a polymeric material, and the elements of which it is created, most often do not take into account with food - fats, alkalis, acids, but it does not always happen.
Harm plastic dishes
In the process of polymerization of elements, not all molecules reach the desired dimensions, and remain active - they can fall from the dishes into its contents, and then into the human body. If you pour hot tea in such a dishes or put hot food, this process goes much faster.
Many plastics products may contain harmful stabilizers, salts of heavy metals and other toxic substances, and all this is heated, and even more reuse can get into our body. That is why one-time dishes cannot be used again.
Cookware from acrylic and styrene is inexpensive and considered unbreakable, but in reality it is not - the styrene breaks especially often. This dishes cannot be used in the microwave, but it can be washed in a dishwasher or manually - therefore, it is assumed to be reused.
Polypropylene is also inexpensive material, and the utensils from it can withstand temperatures up to 100 ° C. It is like to use in picnics and parties arranged in the air; It is allowed to wash it in a dishwasher, but it's better to manually. Polypropylene utensils can be used in a microwave oven.
Polycarbonate dishes can also be placed in a microwave, and wash freely - it is durable. The material is more expensive than the previous ones, and even glasses for alcoholic beverages do from it. The most famous manufacturers of polycarbonate dishes are Strahl, Tuffex and American Tervis Tumbler, guaranteeing the quality of its products. Their dishes are 5-6 times more expensive, but the quality is really good.
Polystyrene utensils withstands different temperatures, and it usually has an appropriate labeling, but most often it is intended for cold products.
Foamed polystyrene is more resistant to heating: in the dishes you can pour hot, and it does not burn hands, since this material does not heat the heat. You can put such dishes in the microwave, washing in the dishwasher and not fear of deformation.
Especially I would like to note the dishes from melamine - a substance from which a variety of formaldehyde resin is obtained in the chemical industry. This dishes often contain too much formaldehyde - and it is toxic for a person, and its number can be ten times more than permissible.
This dishes are dangerous: Melamine itself negatively affects the body, and manufacturers sometimes manage to add asbestos to it, which ceased to be used on all industries, as it can cause cancer.
Formaldehyde stands out when it gets hot, and the drawings on it can be kept due to the use of paint with the addition of lead.
Often, disposable dishes are made of polyvinyl chloride, due to the benefits of this material. It is durable, light, inexpensive, dishes made easily and looks great in a variety of situations.
But manufacturers do not report to the toxicity and instability of polyvinyl chloride: it breaks very quickly - for example, toxins are very quickly falling into a drink from such a bottle, which then turn out to be in our organism.
Of course, doctors argue that this does not represent a serious danger to the body, however, receiving milligrams toxins every time, it is easy to not notice how dangerous diseases will arise.
Any plastic dishes ultimately provides an adverse effect on our health that does not cause tangible problems if it is rarely used - when it is really necessary.
The constant use of plastic dishes leads to a deterioration of health, although many scientists say that this has not yet been proven. In addition, unscrupulous manufacturers from time to time produce plastic dishes from low quality materials, and even with forbidden additives.
In general, it is worth remembering that one disposable dishes are called it because it cannot be used for the second time, but in our country to this prescription often do not pay attention.
Plastic disposable dishes are trying to use as long as possible, although it is impossible to wash or disinfect: the whole infection that falls on it is preserved and multiplies, transmitting to everyone who uses this kitchen.
It is not clear why you need to use disposable dishes if you have to wash? Then it is better to use porcelain or glass ...
Discharge disposable dishes immediately after use - it is for both invented to save us from unnecessary work.
Combating manufacturers always label their products, and on plastic dishes there are designations in which it is worth understanding. First, remember at least the fact that the PS marking is a polystyrene, and you cannot pour it into such a dishes and put it hot, and otherwise you will receive a portion of toxins that destroy the liver.
PP is polypropylene. This material is resistant to heating, and from such a dishes you can drink hot coffee, and there are hot dishes from the plates. However, if such a dishes are intended for one-time use, then the second time should not be used.

We are heard about the dangers of disposable dishes for human health, but still it is produced annually by millions of tons. Why? Yes, because there is a demand.
No picnic in nature or quick snack at work does not cost without plastic plates, cups, spoons and knives, and all because it is incredibly convenient.
Nevertheless, the Ministry of Health strongly recommends refuse to use plastic dishes. Hazards is just the material from which it is made. Together with food in the human body, the dose of lead, manganese, cadmium, and formaldehyde resins, which are part of "plastic assistants", cause scary allergies and diseases.
Of course, it is environmentally friendly dishes that does not harm human and the environment. More about materials from which the names familiar to us are made, you will learn from the article.
Plastic and everything connected with it
Most often, disposable dishes produce from three plastic species:
- Polystyrene - dishes made of it are marked with PS letters, designed exclusively for cold products and is characterized by white. Even no long heating contributes to the selection of styrene, which is very harmful to health.
- Polypropylene - brown dishes with RP marking may heat up to a temperature of +150, but not intended for storing fatty and oily products.
- Polyvinyl chloride (PVC) - dishes often make dries and containers, marked with PVC letters and is not at all intended for storing food.
But the most danger of health is dishes from melamine. It is translucent and painted in the most different colors.
Paper dishes or how to save health and ecology
Cookware, which is universally used abroad and is absolutely safe, made of paper. It possesses such characteristics:
- It does not heat up very quickly, while maintaining heat, so it can be used for storing hot products.
- Thin cardboard, due to the lamination procedure, is not aturnaling from condensate.
- Such dishes can be used for heating food in microwave ovens, since it, under the influence of high temperatures, does not distinguish harmful substances.
The most important advantage of paper dishes is that it cannot be reused, and in the case of plastic, this important rule is often neglected.
In this video, it describes in detail how disposable dishes are made:
Plastic bottles, containers and dishes are firmly entered into our life. But far from all the mistress owns full information about the degree of harm of plastic for the human body.
The most common polymeric materials (plastics, plastics) are polyvinyl chloride (PVC), polypropylene, polyethylene, polystyrene and polycarbonate. Of them produce both technical and food plastic.
Text: Elena Omelchenko.
Plastic plates spoiled from additives
By themselves, polymers are inert, non-toxic and not "migrate" in food. But here are intermediates, technological additives, solvents, as well as chemical decomposition products can penetrate food and have a toxic effect on a person.
This can occur during food storage or when they are heated. In addition, polymeric materials are subject to change (aging), in which harmful substances are distinguished. At the same time, various types of plastic become toxic under different conditions - some can not be heated, other washing.
Polyvinyl chloride is a polymer based on chlorine. It is cheap and therefore widespread all over the world. From PVC make bottles for drinks, cosmetics boxes, containers for household chemicals, disposable dishes.
As PVC agrees, it begins to allocate a harmful substance - vinyl chloride, which is carcinogenic. Naturally, from the bottle, he gets into a gas meter, from the plate - to food, and from there - directly to the human body.
Highlight this dangerous substance Bottle from PVC begins approximately a week after the contents were filled. A month later, several milligrams of vinyl chloride accumulate in mineral water. From the point of view of oncologists, it is a lot.
Often, plastic bottles are used again, they pour tea or morse in them and even alcoholic beverages. In the markets in plastic bottles, milk and oil are sold; In dachas, large five-liter bottles are often used to store water and other drinks.
However, experts are unanimous: nothing but water cannot be reused. Yes, and then not in everything. You can only use PET bottles. From PVC bottles (i.e., a toxic chlorvinyl is distinguished from bottles made using PVC). Such bottles should have a special sign on the bottom: Troika in a triangle.
Harmful containers can be recognized in the influx on the bottom. It happens in the form of a line or spear about two ends. But the surest way is to click on the bottle of the nail. If the tank is dangerous, it is formed by a whitish scar. "Right" bottle remains smooth.
However, many experts are confident that any bottle plastic retains neutrality only in the absence of access of oxygen, that is, while water retains its original chemical composition. As soon as the bottle opens, water quickly changes its properties, after which the plastic inevitably changes its properties.
For the first time - this is the dishes, in the second - Piva
With the advent of disposable plastic dishes, we all became its active users. In fact, as it is convenient not to drag a heavy bag with you to a picnic, but stock packaging-other disposable cups, spoons, forks, plates of different sizes.
Plastics themselves rarely can adversely affect the person. But to make them more durable, in the manufacture of plastic add special substances-stabilizers. Here in them is the main danger to the health of users.
It turns out, polystyrene, from which most disposable dishes make, becomes toxic when heated due to the styrene released toxic compound. Thus, it is worth pouring a hot drink into a glass or put a hot dish, it can not be called safe. But polystyrene plates (PS) are often used in summer cafes under kebab or even under hot soup.
Plastic disposable cups that are made from polypropylene (PP marking) to hot liquids "indifferent" and harmful substances during heating are not highlighted. But they have a different property: when contact with alcohol or carbonated drinks (in general, with any complex chemical compounds), such cups can highlight formaldehyde or phenol. That is, water can be drunk from such a glass, but vodka, - no longer worth it.
In order for plastic dishes to be safe, it is necessary to use it strictly for its intended purpose. Food plastic of different grades has different properties. One brand of this polymeric raw material is designed to produce bottles for water, the other - for bottles with carbonated drinks.
Cups for yogurt are made of plastic such a brand, which allows the casting method to make a light and cheap container, while neutral with respect to the dairy fat, and the pudding cups must resist sugared.
Therefore, experts insist: in no case cannot be used plastic packaging as containers for food storage, and disposable dishes - repeatedly.
As plastic responds to contact with the ingredients, for which it has not been intended, which connections may be formed at the same time, no one explored. Particularly cunning fats and acids that can pull out free toxic compounds from plastic.
There is another important point. Before the secondary use, a plastic container must be washed. Disposable packaging was not intended for washing, so the result is unpredictable. The selection of plastic from all sorts of compounds is multiple times with heating. Therefore, only special containers can be used in the microwave oven.
If you periodically buy fast food products, requiring only a few minutes of heating in a microwave or oven, do not be lazy - put the food to ceramic or enameled dishes, and then heated. Taste properties will not change from this, but you can avoid dangerous health: often manufacturers go to different tricks to reduce this or that product.
The exception is frozen ready-made dishes in the trays: dishes can be warm in the microwave or oven, since they are made from crystallized polyethylene terfthalate. Properties of this compound remain unchanged in the range from -40 ° to +250 C.
True, some brands may lose the necessary heat resistance, after being subjected to deep cooling. By the way, if the label says that the dishes can be washed in the dishwasher, it means that it is stable and to heating.
Plastic code
At one time, special international labeling was developed to simplify the sort of plastic: the triangles formed by arrows with a number inside. The digit indicates the type of plastic. Instead of a number or under a triangle simultaneously with the digit, you can find the letter code of plastic:
PET: Polyethyleneter-phthalate: bottles for carbonated drinks, water, juice, dairy products, vegetable oils, cosmetic products, etc.
HDP: High density polyethylene: packing bags, garbage bags.
PVC: Polyvinyl chloride: Construction and finishing materials, Furniture, Shoes, Medical products, Water bottles, Packaging Food
LDP: Low density polyethylene: bottles for detergents, toys, pipes
Pp: Polypropylene: Medical Products, Cookware for Hot Dish, Packaging Food Flat
PS: Polystyrene: disposable dishes, cups for dairy products, yogurt, electrical insulating film.
Glass and fork Yes Plus Snow
In accordance with the Law "On Consumer Protection", any manufacturer must marked its products. Food plastic has a generally accepted labeling - the "Glass and fork" icon. It may be written on the product that it is designed for cold, bulk or hot products, for use in a microwave or freezing, sometimes the temperature range is indicated, within which it is possible to use the subject.
"Snowflakes" indicate that the container is suitable for freezing products, "stove with waves" - that in this dish, you can warm up food in a microwave furnace, and "Tarves under the shower" suggest that the containers can be washed in the dishwasher.
All types of plastic used for the production of products in contact with food are necessarily undergoing an examination for compliance with sanitary and hygienic standards. But at the same time, the compliance with the declared intended purpose is checked: that is, if the manufacturer indicates that the plastic product is intended for storing drinking water, it is checked as a container for drinking water.
How to pack to save
Any packaging materials, even the most modern, have certain restrictions on use in everyday life. For example, film-covered products cannot be warm up in a microwave oven (except for cases specially specified on packaging).
Heating, as in the case of disposable cups, can run the release process from polyethylene potentially hazardous chemicals. For the same reason, it is not necessary to cover the film very hot food, besides, the moisture will be actively concentrated under it, which can lead to the loss of taste quality of the product.
You cannot be placed in the microwave and in the oven, the combat paper is a type of packaging fine paper covered with a thin layer of paraffin. As a rule, it is used to cover the surface of thick creams, puddings, cottage cheese to prevent the formation of a dry crust.
Aluminum foil is a practically safe type of packaging material that protects products well from moisture loss. It does not matter which side of the foil concerns the product - smooth or matte.
Wrapped in foil products cannot be warm up in a microwave oven - but not due to the potential harmfulness of the heated foil, and due to the ban on the installation in the microwave metal and metal-containing items in the microwave oven.
Recently, we are increasingly stored food in plastic containers: they are comfortable to take cooked dishes with them to work or to visit. The only limitation was stipulated above: Avoid heating plastic. To do this, it is necessary before heating on the stove shift the products into ordinary dishes, and vice versa, do not shift in the container of another hot dish.
Glass containers, in contrast to plastic, are absolutely safe to use, unless they do not beat them. Glass is more practical and more durable plastic, it is easier to wash it. Before laying foods in glass containers for long-term storage in the freezer, or installation of a dish in the oven, check if the specified glass brand has increased or reduced temperature modes.
Ceramic containers have long retain products and contribute to neutralization of smells of highly smelling products (for example, salts and peppers). It can not be used in the oven or cook in it food on the stove if there is no label "heat-resistant" or "suitable for use in a microwave".
I would like to say a few more words about tin cans - because it is also a kind of type of product packaging. So that the metal does not in contact with food, the inner surface of cans is usually lined with a plastic film containing befenol.
As the product stored, the polymer material, from which the package is made, highlighting a toxic befenol, which can go to the contents of the can. Therefore, it is very important to observe the life of the products: because it refers not only to the product itself, but also to its packaging.
And it is better to minimize the consumption of canned minima, and when opening canning can be immediately shifted in glass or ceramic dishes. After all, under the influence of oxygen, the corrosion of the surface of the canning can be enhanced, and the content of toxic substances begins to increase.
American scientists argue that up to 80% of the "plastic" substances found in the body of the human body fall there from construction and finishing materials, in particular, from such popular plastic windows, furniture, but most of all - from the dishes: from food plastic All sorts of connections are moving into products Nutrition.

- What are the hygienic features of using disposable plastic plates
Disposable dishes are a good help for organizing events. Public catering enterprises began to use plastic plates for their guests. Information that such a dishes consists of polystyrene and polypropylene did not interfere with the demand of this product. Disposable products have an advantage - their low price in comparison with paper counterparts. In our article you will familiarize yourself with the history of disposable plastic plates, and also learn about what areas they are popular. We are promoting all myths about disposable dishes.
The history of the creation of disposable plastic dishes
Disposable dishes appeared more than a century ago thanks to one American student named Hugh Moore. He turned the cardboard sheet into the cone, and turned out a mug.
The thought to make such an improvised paper vessel came to a student while visiting public catering. Hugh Moore was dissatisfied with dirty, carelessly washed dishes offered to him. He wrote an article where he expressed his attitude to what the food was served in the catering, and also outlined his idea. His story and notion received a large response among people of that time. Businessman Lawrence Luelllen became interested in the invention Hugh Moore and decided to make a mug better. Thus, Lawrence Luelllen became the first to start selling disposable dishes.
In 1907, Luelllen decided to equip the clermed paper cups invented by them machine guns with gashed water. He received a patent for this idea. By 1960, in America, a trade of paper cups reached $ 50 million per year.
In 1910, the patent received a "safe cup" (SAFE CUP) - a leaf of cardboard twisted.
1947 became the year of the appearance of Tupperware plastic dishes. Erl Silas Tapper has developed a method of producing a rigid low-fat plastic from a black polyethylene slag by cleaning it.
How to produce disposable plastic plates
The process of manufacturing plastic dishes is based on the following steps:
- the raw material is heated in the extruder and mixes to the desired consistency;
- hot mass is processed under the press, as a result of which plastic film is obtained;
- the canvas is placed in a thermoforming unit, which gives the form to future products;
- using a trimmer from the film, blanks are cut;
- the finished plates are folded into the stacks and pack.
Varieties of disposable plastic plates
Disposable plates are functionally different. They can be divided into the following groups:
- by material manufacturing: Made of paper and plastic; The surface of paper dishes is subjected to lamination so that it can eat liquid food from it;
- by diameterfrom small to large;
- in depth:for liquid food - deep, for solid - flat;
- by density: Thin and dense, the second allows the product not to lose its temperature. For the same purpose, the plates with double walls and lid can be used;
- by color scheme: The color of the plates is very diverse, it is possible to choose products with a pattern suitable for one or another event. Commercial companies often ordered disposable plates with the image of the logo or applying inscriptions;
- by configuration: Round, triangular, rectangular, oval, etc.;
- registration: with smooth or carved edges;
- for special purpose: Disposable foil dishes, intended for baking in the oven, as well as dishes with separate sections, so that the food is not mixed.
Choosing a disposable dishes, the properties of each of the above groups should be taken into account.
What kind of disposable plastic plates are better by properties
Round white disposable plates having a small thickness are the cheapest, and therefore they are most often used in affordable catering. From these plates, it is convenient to eat room temperature, but for hot and cold dishes they no longer fit.
The choice of color and form of disposable plates depends on the individual preferences of the consumer. For example, to create a festive mood on a merry event, bright utensils of an interesting form will suit. In order to be conveniently applied to different food and at the same time not to mix it (for example, meat, salad), there are disposable plates with partitions. Such dishes are like lunch boxes. These plates are well suited for a buffet or picnic in nature, when there is no possibility to sit at the table.
For which disposable plastic plates use
The scope of disposable dishes can be symbolically divided into two groups.
Household is the retail sale of one-time plates (one piece or small packages) for ordinary people. Industrial consumption is the purchase of dishes in large volumes (Wholesale and small wholesale) by organizations and enterprises. Accordingly, firms acquire plates at a lower cost per piece.
In ordinary life, disposable plates are often used for:
- Trips to nature and picnicswhere it is impossible to wash the dishes, because there is no clean water nearby.
Thus, in nature it is more convenient to throw a disposable dishes than carrying home dirty. If you plan to light a bonfire in the forest, then it is better to bring paper dishes with you, which can be further burned without prejudice to nature;
- For family events with lots of invited people (most often it concerns events held on the street) .
When there is a use of plastic or paper plates, the organizers of the holiday can be calm that dishes are enough for all guests. Purchase of several packs of disposable dishes will help with the solution of this issue;
- For children's holidays, on such events you can please the children with colorful plates with the image of your favorite cartoon characters and fairy tales; Disposable dishes in this case are also relevant because it is safe for children (it is impossible to break it and drowned about the glass).
In the trading area, disposable plates are most needed in enterprises that organize public food, it is:
- budget canteens and snack barsthat thus protect the money so as not to spend their jobs for dishwashers;
- outletsproviding takeaway;
- large fast food networksHere disposable plates are used, not only to keep money, but also to show the organization's solidity. For such companies, dishes are made to order with the application of a logo and other corporate information.
Another mass consumer of disposable dishes are organizations that are not related to the work of public catering institutions. Business buffets, tastings and other activities involving the treats are often conducted not in special banquet halls, so the use of one-time dishes will save money and time of employees.
True and myths about disposable plastic plates
Literally 10 years ago, plastic dishes were completely consumed and was unusual. Over time, people began to wonder about her safety. We found the most famous opinions about the one-time dishes and tried to find out that of them the truth, and that the myth.
Polymers from which disposable dishes are made are absolutely harmless: though
Yes, safe. Before launching polymers into mass production, hygienist scientists carefully studied their properties in laboratories. The result of the study was that if you observe all the technological features of manufacturing products, and it is also properly used by one-time dishes, it does not make harm to human health.
Based on the positive toxic and hygienic assessment of experts, the Ministry of Health allowed the massively producing disposable dishes.
Plastic products can be used several times: myth
If you have purchased a drink in a plastic bottle, then you should not use it in the future for storing a morse, water, milk and other liquids. The dishes are called "disposable" just because it is not intended for repeated use: high temperature, long-term contact with food, oxygen and UV rays contribute to the aging of polymers.
As a result, low molecular weight substances are formed in them, which go to food stored in such dishes. The liquid that has absorbed these components becomes unsuitable for drinking.
Polymers can cause cancer: though
With uncontrolled production and improper storage, the polymers begin to allocate up to 15 different toxic compounds with an unpleasant specific smell into the environment. After hitting the human body together with food, they are able to cause a sense of discomfort, fatigue, headache, allergies, bouts of bronchial asthma. Animal experiments have shown that individual compounds can be the basis for congenital deformities and malignant formations.
Domestic plastic safer imported: not always
The country of origin of plastic dishes is not so important as a firm that does it. On disposable plates of good quality should be the code, type of manufacturing material and the scope of use ("for food products", "for bulk products" "for cold water", etc.).
By purchasing plastic dishes from a dubious manufacturer, you can harm your health: the composition of poor-quality materials produced by the handicraft method can include heavy metals, insignificant dyes and other hazardous substances.
Hygienic features of the use of disposable plastic plates
We often use one-time plastic dishes in household life. She has advantages compared to glass dishes - plastic is not beating, it is easy, durable and no need to wash it.
Information that the material from which plastic dishes are made is not dangerous for a person, faithful. Disposable dishes are created from polymers. Before launching goods into large-scale production, in specialized laboratories, the influence of polymers on human health is investigating. Provided that plastic dishes were produced in all technological rules, and also used in its direct intended purpose, it will not cause any damage to people's health.
Currently, the hygienic assessment of materials and products in contact with food products is carried out in accordance with the technical regulations of the Customs Union "On the safety of packaging" TP TS 005/2011.
In order to avoid the negative effect of products from polymers, some rules should be followed. The first is when buying a product Look at the manufacturer's company. If the company has proven itself as a law-abiding, following all production standards, the product will be printed on the product, as well as the composition. Pay attention to the scope of dishes (for liquid, solid, bulk components, for hot and cold products).
For reliability, it would not hurt to learn to understand the special designations on the product (code). Suppose if there is a sign in the form of a triangle of three arrows at the bottom of the vessel, then this indicates the possibility of further recycling material and a closed cycle of use (creation, application, recycling). Inside the triangle, figures are often indicated by which the type of material can be recognized (1-19 - plastic, 20-39 - Paper, Cardboard, 40-49 - Metal, 50-59 - Wood, 60-69 - Fabrics and Textiles, 70-79 - Glass).
PS (PS) or digit 6 shows that there are polystyrene in the product. In such a dish, it is necessary to keep cold products. When contacting with hot food or when heated in the microwave, these plates will highlight a poisonous styrene.
PP (PP) - polypropylene, these letters are sometimes replaced by a pattern of fork and a glass or figures 0.5 and 1. This type of dishes can withstand the temperature above 100 ⁰C, that is, it can be used for hot meals and drinking (tea), as well as It is used to heat the meal in the microwave oven.
Polymer products should be used only once. With repeated use of one-time dishes, its protective surface is disturbed, which leads to the release of toxic substances, such as cadmium, lead, formaldehyde, phenol, which can later have a negative impact on the human body.
High meat or air temperature, long-term contact with food particles, UV rays, oxygen causes the aging of materials from the polymer. As a result, poisonous substances are distinguished from them, which, in turn, are transferred to food contained in the disposable container. Following all the rules of using plastic dishes, you will not harm any harm, but only make life more comfortable. However, it is better to resort to this type of products not too often, but as needed, for example, in a tour, leaving on nature, to the country area.

Cups and mugs, all kinds of depth of plates, multicolored knives, plugs and plastic spoons are produced every year by millions of tons. Without this uncomplicated serving, there is no one party at work, a picnic, and sometimes even a coffee break on business meetings. The use of such packaging is convenient and saves a lot of time - here is perhaps all the advantages of disposable dishes. The minuses are much more.
Disposable plastic packaging is not decomposed, it can not be burned, and being thrown out into the street, it turns the city into the garbage. But that is not all. Plastic packaging is able to harm the body of its consumer. About the existing danger manufacturers, of course, do not report anything, but the toxicity of products does not become less.
What plastic dishes made from
The most common materials for plastic disposable dishes are polystyrene, polypropylene and polyvinyl chloride.
Polystyrene.
Cookware from it white. On polystyrene indicate two big letters PS. This means that the packaging is intended only for cold food. When hot tea or coffee poured into such a container, plastic heats up and starts to highlight styrene. The same happens when the products are heated in a polystyrene packaging in the microwave. Of course, the one-time getting of styrene in the body does not bring damage, but if you constantly buy lunch in such a package and warm it in the microwave oven is accumulated in the body. What subsequently can lead to a violation of the work of the kidneys and liver.
Polypropylene
From polypropylene, a disposable brown dishes are obtained, for example, coffee cups. Unlike polystyrene, polypropylene utensils with PP marking does not change its properties even when heated to +150 s, but is easily chemistry, highlighting formaldehyde and phenol, which are also dangerous to health. Therefore, drinking alcohol from such dishes is not worth it. Polypropylene containers and for storing fatty substances, such as cream or sunflower oil, because, when contacting with fats, polypropylene is destroyed and formaldehydes and phenol are distinguished.
Polyvinyl chloride
But the polyvinyl chloride plastic container is most dangerous. We label it with PVC (PVC) letters. From this substance usually make containers. It actively distinguishes vinyl chloride - a carcinogenic substance that can cause oncological diseases. Therefore, it is better to choose disposable dishes with the designations of PS and PP.
Special attention deserves dishes from melamine - Substances from which formaldehyde resin is obtained in the chemical industry. Externally, such a dishes are like a porcelain, but much easier and stronger. Package from melamine - record holder in terms of harmful substances contained in it. Firstly, such a package contains a lot of formaldehyde, and it has toxic properties, and its number can be in tens of times more than any permissible norm. Secondly, besides the melamine itself, which negatively affects the body, the dishes may contain asbestos. Although its use for the manufacture of packaging is prohibited, as it causes cancer. As soon as hot food falls into such dishes - poisonous formaldehyde is distinguished. In addition, lead lead can be added to the durability of drawings in the paint, which is also dangerous to health.
But how to be if these labels are simply not available on the product?
How to distinguish polypropylene utensils from polystyrene or polyvinyl chloride?
Pressing a solid object on the product from polyvinyl chloride on its surface a trail is formed, the surface of others will remain smooth. Polystyrene utensils during deformation makes a loud crunch and easily cracks, and it softened when heated. Polypropylene - during deformation it does not break, but only bends, and when heated is not deformed.
Correct choice - Paper dishes
It is produced from natural raw materials and without harm to the environment is quickly disposed of. In addition, Paper from paper longer maintains heat and has a lower thermal conductivity, which allows you not to burn your hands. When heated, harmful substances are not highlighted.
Paper cups are made of fine cardboard. It can be laminated with one or both sides. The lamination of the outer layer prevents the glass from turning on a hot day when condensate may form on it. Thanks to modern technologies, the edges of paper cups glue without glue. A strong compound occurs due to ultrasonic or heat treatment of the laminated layer.
Compared to plastic and polystyrene cups, paper - safe material for microwave ovens. It is made of natural wood with small additions of other safe substances.
Terms of use of disposable dishes
Disposable dishes should be disposable. Never use disposable dishes several times. After all, it is impossible to wash it up to hygienic purity after use, and microscopic damage and cracks will further enhance the release of harmful substances.
In plastic dishes, it is impossible to store products and all the more, warm them in the microwave. Not suitable for microwave plastic containers, for example, from ice cream. In the freezer with them nothing happens, but under the action of high temperatures they can deform. Plastic at the same time begins to decompose and highlight hazardous substances. In addition, the destruction of plastic occurs under the action of oxygen, sunlight and room heat.
