How to glue greenhouse film. How to glue a plastic wrap for a greenhouse yourself

How to glue plastic wrap? This seemingly simple question constantly puzzles many summer residents and gardeners.

After all, if you first decided to build yourself a greenhouse, you will have two options - to purchase a ready-made one (the pleasure is not cheap) or to glue the film of the required width.

To facilitate your searches, we present quick guide on how to glue polyethylene film.

First you need to purchase polyethylene in the required amount, at the same time take with a margin, since you need to overlap. Is there plastic wrap?

This means that you have very few tools left, namely: an iron, sheets of paper and preferably two assistants, plus a table or other flat surface.

The welding of the film is carried out according to the following scheme: take the film and overlap the edges to be glued (the width of the overlap should be equal to the width of the used iron with a margin of 5 centimeters).

The prepared paper (you can use a regular newspaper folded in half) is laid slightly wider than the overlap.

We take two small segments and use the "stick-on" method to select optimal temperature, at which the welding of the polyethylene film will be carried out

If this is not done, then when gluing large pieces of film, it may become unusable, melting due to too high an iron temperature or an exceeded holding time.

After selecting the temperature on the table, we make gluing, it is advisable to have two assistants who will not only move the glued film evenly, but also level the finished overlap.

Note to everyone who will glue the plastic wrap - the paper should not be removed immediately from the hot film, in order to avoid tearing.

Let it pause a little and then shoot.

In conclusion, we note that plastic wrap for greenhouses is very easy to stick together at home.

However, if you need to cover the greenhouse big size, then look in hardware stores for a special apparatus for gluing polyethylene and it will become much easier for you to work.

The welding of film panels can be done in two ways.

Film bonding method 1

Place one sheet of film on top of another, cover them on top with a newspaper or fluoroplastic film, then slowly slide the edge of an iron, a soldering iron tip or a roller over the junction of the sheets, preheating it to 250 ° C.

Film bonding method 2

You can connect the edges of the panels as follows: clamp them between 2 smooth strips of metal so that the edges of the film protrude from under them by about 1 cm, and melt them with the flame of an alcohol lamp or blowtorch.

For gluing the film, you can also use xylene and trichlorethylene, heated to 70 - 75 ° C. At a temperature of 30 ° C, film panels can be glued with 80% acetic acid. If you have chosen one of the above substances for joining the parts of the film, be extremely careful when working with them.

The film can be glued with BF-2 or BF-4 adhesives, having previously treated the surfaces to be joined with a 25% solution of chromic anhydride. For joining polyamide film panels, PK-5 glue is best suited. Be sure to iron the seam obtained after gluing with a warm iron heated to a temperature of 50 - 60 ° C.

More recently, superglue has appeared on the market, which is designed specifically for plastic wrap.

How to solder a bag with an iron

It gives a very strong, water-resistant and elastic connection. In addition, it is absolutely odorless, and the compounds are transparent and practically invisible. One 50 ml bottle of glue can be used to glue a seam 15 - 20 m long.

Since superglue contains solvents used in the home, it is recommended to follow the same precautions when working with it as when using household chemical substances... If stored in a sealed package, the shelf life of the glue is not limited. If it dries, it is enough to dilute it with acetone to restore its original properties.

Superglue is also useful for repairing finished film coatings. The way to use it in this case is as follows. Apply with a brush or stick thin layer glue around the damaged area with outside film coating. Let it dry for 2 hours. Then cut out a patch of the required size from the film, attach it to the damaged area and smooth it well. Superglue can even glue old film... However, you should know that it is best to repair the film coating in sunny weather.

If you want to sew film panels with threads, overlap each other. Sew the stitches infrequently. To increase the strength of the seam, make a paper interlayer. This method of joining film canvases is most often used if it is necessary to apply a patch to the film covering before pulling it onto the frame or when the already stretched film breaks.

Minor damage to the film can be sealed with adhesive tape.

But, first of all, we are talking about the design of waterproofing screens for various structures. And, since such a technological screen is not a "cast" part, many are interested in the question of how to glue the film so as not to lose the unique waterproofing properties of the finished polymer product at the junction?

Why is it necessary to weld and not glue the film?

The fact is that absolutely reliable gluing of polyethylene practically does not exist - this material only needs to be welded! Moreover, weld with a special apparatus. And the most reliable welding method is the hot wedge method. Therefore, if the question arises of how to glue polyethylene to achieve maximum waterproofing, it should be remembered that such a structure is much safer to cook than to glue!

How to solder the film?

How to glue the plastic wrap is, of course, everyone decides for himself, taking into account the specific requirements for finished product and their own capabilities. But, if we are talking about reliable waterproofing screens - especially large industrial products - then, as a rule, there are no questions about how to glue pvc film or how to glue polyethylene. Obviously, such screens only need to be cooked using special welding machines that can be purchased on our website.

Polyethylene welding technology

Experts are sure that in order to obtain a waterproofing screen with a reliable seam, it is necessary to use a special "hot" welding. When using it, the cut parts made of polyethylene are literally soldered into a single fabric.

How to weld plastic wrap correctly?

Of course, you need to understand how to solder the film correctly - without flaws in the form of a loose seam or missing places. When asked how to weld the film in order to get a reliable waterproofing product, the managers working on our website will always recommend one of the welding units that will cope with the task as accurately as possible. But, before giving you recommendations on how to solder a plastic wrap or how to weld a plastic wrap, they will need to know all the conditions of the upcoming work, as well as technological and operational

If you want to seal a regular plastic bag with a household iron, then yes, it is possible. But, if you want to seal a resistant bag, it won't be so easy. These bags are sealed using industrial heat-sealing methods in large factories.

Resistant bags are usually sealed with special sealing machines. They are different sizes and power. The heat seal process is used for most specially printed or plain bags and is actually the last step in packaging a product into a bag.

There are two types of plastic used to make doypacks - thermosetting plastic and thermoplastic. Typically, barrier bags that are made of thermoplastic can be re-welded. But the results will not be very good. Packages that are made of thermosetting plastic cannot be welded with an iron.

Having agreed that a doypack cannot or should not be sealed at home with an iron, let's think about why this might be needed. The only logical explanation is to keep the content safe after the package has been opened.

It turns out that if the manufacturer makes bags with ZIP locks, customers will not have an idea to brew the bags at home. There are two types of ZIP locks - single and double, depending on the requirements of the product being packaged.

Installing a ZIP lock on the package does not add much to the cost. But it makes storage of the product easier. Customers generally prefer packages that are easy to store, which means more sales for businesses that use ZIP locks.

How to solder plastic wrap at home?

Basically, a few extra cents you spend on a ZIP lock will lead to more sales.

Returning to your original question, DO NOT use an iron to seal the bag. Instead, buy groceries that come in bags with zip locks. Thus, you can seal them again after use. It's easier and safer to keep your food crispy and protected from moisture!

Polyethylene is a thermoplastic polymer that exists in various modifications with unique properties. This is due to the branching of the structure of its macromolecules.

This article will focus on the main properties of polyethylene and its areas of application.

What are the main properties and characteristics of polyethylene?

Polyethylene is an opaque polymer in a thick layer. It crystallizes at temperatures from -60 to -269 degrees. At temperatures above 80 degrees, it first swells and then dissolves in aromatic carbon. Among its main properties and characteristics, the following are distinguished:

Polyethylene is resistant to the action of aqueous salt solutions, alkalis, acids, but at temperatures above 60 degrees it will still be destroyed by sulfuric or nitric acids.

Not absorbed at room temperature organic solvents... You can read more about this on this page.

If this polymer is treated with oxidizing agents such as a chromium mixture, this leads to surface oxidation. It is moistened with water, adhesives or polar liquids, which leads to the possibility of gluing products from this material.

The more branches in the structure of polymer macromolecules, the less crystallinity of the material. This determines its properties and density. Low density polyethylene films are up to ten times more permeable than high density analogs.

The higher the degree of crystallinity and molecular weight, the higher its mechanical properties.

How to glue the bag

This determines the flexibility, transparency and rigidity of the finished product.

Applications of polyethylene

The scope of polyethylene is wide enough. It directly depends on its characteristics. The polymer is used for the production of the following goods:

Packaging, agricultural and shrink films. These products are in demand all year round.
Water supply, gas, pressure and non-pressure pipes. In production, these elements are essential materials.
Sanitary ware, fibers and building materials. Basically, these products are seasonal, but they are in great demand in the market.
Canisters, cisterns, bottles and other containers, as well as household items.
Car parts and various equipment that will always be relevant.
Internal prostheses.

Polyethylene is universal polymer which thanks to its unique properties widely used in production.

Many summer residents sooner or later face a problem. There are two solutions here - to buy a ready-made one, but it is not cheap, or else to glue the material to the required width on your own.

It is possible to do this at home, especially if in question about a small greenhouse.

For work you will need:

directly polyethylene, but with a margin, since it will be necessary to overlap,
paper,
iron,
flat surface, such as a table,
if possible, two assistants.

How to glue pvc film - stages

Overlap two pieces of material.
Lay paper or ordinary newspaper, folded in half, so that it is slightly wider than the overlap.
Heat the iron, test on two pieces the optimal temperature at which they stick together. This will prevent a large piece of film from ruining.
Apply the iron to the overlap, while one assistant should level the joint, and the second should evenly move the material.

It is impossible to immediately remove the paper from the junction, as the pieces of the glued area may break. You must wait until it cools down.

If you have to cover a large greenhouse, you can purchase a special apparatus that will allow you to quickly and efficiently fasten wide pieces, and then the instructions, how to glue the film with an iron, not required.

Artificial reservoirs are popular and in demand today. This is a beautiful element landscape design that can be found on many suburban areas... Someone sets up small ponds, someone makes large reservoirs, plants plants around them, starts fish.

For creating high-quality waterproofing any pond, regardless of its size, use a durable film - simple and inexpensive material... Its advantages also include durability, environmental friendliness, resistance to ultraviolet light, pressure, temperature extremes.

With it, you can create reservoirs of various widths and depths, it does not interfere with the cultivation of plants, animals and fish, and it is allowed to install this material even in winter time of the year.

VIDEO INSTRUCTION

The film must be selected based on the depth of the pond. So, if this figure is 75 cm, then the film thickness should be about 0.5 mm. For reservoirs up to one and a half meters deep, PVC with a thickness of 1 mm is purchased. Well, for deep ponds, butyl rubber EPDM is already suitable.

It is more convenient to lay the material in one whole piece, but often this is not possible, so the question arises, or the pond.
The first step is to remove dirt and dust from the coating.
Before laying the film, the pit is first cleared, stones, debris, tree roots are removed, the bottom is leveled, and a sand cushion is created. Boards are placed under the edges of the material, which are left even after the completion of the work.
Next, two pieces of film are placed on top of each other with an overlap of about 7 cm wide.
To connect the EPDM, you need a neoprene assembly adhesive or a special tape. PVC foil can be bonded with PVC glue or sealant.
The composition is applied in a thin layer on both sides, let dry for ten minutes and connect the lower and upper edges of the film.
The place of gluing is rolled with a silicone roller across the seam, then along. You need to press hard so that all air bubbles come out.
On the last stage a plastic spatula is used, with which the entire seam is leveled, and it is additionally treated with an edge sealant. The result is a smooth and very strong connection that will provide reliable waterproofing of an artificial reservoir in summer and winter.

Film welding is one of the working steps that can sometimes be necessary. In many types of work, pieces of polyethylene film must be tightly connected together. Most often this is necessary for the construction of a greenhouse, greenhouse, installation of vapor barrier during construction.

For some activities, it is necessary to ensure the material is sealed in order to obtain a product. When gluing polyethylene using adhesive tape or adhesives, high-quality sealed joints will not be obtained, therefore, if necessary, to ensure a strong connection, welding is used.

There are many ways to weld polyethylene film. The operation itself is the bonding of layers of material by heating, creating a temperature convenient for melting. When the layers are compressed, weld.

Welding of polyethylene is as follows: When heated, the layers change their structure, join at the molecular level, and after cooling, a strong seam is formed.

To glue the plastic wrap, the layers must be well cleaned - for any contamination strength characteristics are much reduced.

Foreign impurities pass into the melted mass, which violate the molecular structure in the seams.

For a high-quality connection with high strength, it is necessary to observe following conditions:

when welding the film, its pieces must be homogeneous, belonging to the same batch;
surfaces must be clean;
temperature regime when working, choose the right one - with insufficient heating, the strength deteriorates, with excessive heating, the joint and the pre-seam area are deformed;
when heating, ensure sufficient compression.

To connect PVC film good quality, you can not re-weld the edges of the material. If it is necessary to perform such an operation, first cut off the damaged edges.

Both in the implementation of construction operations and for household needs, the following connection methods can be used:

welding with a soldering iron equipped with special nozzles - at the same time it acts as a homemade welding machine;
joining when heated, melting the film with an iron;
desired temperature layers is achieved with a burner;
industrial equipment is used to heat the seam.

You can try to warm up the film with a hair dryer, then tightly connect the surfaces intended for gluing with each other, or it is better to put it under a press.

Film welding with a soldering iron

How to glue plastic wrap with a soldering iron? This method can be safely attributed to the most common - the tool is easily accessible, it allows you to get a good result, and with a little refinement of the soldering iron, the effect can be improved.

It should be borne in mind that without modification it will not always be possible to make a tight connection - the joints may be uneven, the material spreads.

So you can glue the greenhouse film or make a canvas for other needs. Only for very small amounts of work can the connection be recommended for use PVC Soldering Iron... After a little refinement, it turns into a convenient and easy-to-use tool.

Iron as a welding heater

How to glue the film using an iron - the simplest household appliance that is in every home? Everything is very simple - the work consists in melting the polyethylene and creating joints using the heated soleplate of the iron.

Improvised welding machine from the iron allows you to connect large areas of film... In this case, the seams can be made with a certain width. All modern irons have a thermostat that allows you to adjust the heating temperature.

Before gluing the film, ensure comfortable spot for work - a smooth wooden surface is best.
The film is laid with an overlap, the top layer is covered with fluoroplastic or paper, the sole of the iron is pressed and led along the welding line.
The clamping speed, force are determined empirically, the temperature is selected.

Professional tools for welding

To connect the film at home, you can make a variety of tools with your own hands, but they are suitable only for performing small-scale work. If necessary, large-scale production - commercial activity, the creation of a greenhouse or greenhouses - the use of these devices has the greatest effect. No adhesive has the same ability.

The welding process is faster, professional devices allow you to set the desired pressure parameters, the speed of advancement along the weld, and temperature.

Most professional devices have tension and guide roller elements that pull the film at an optimal speed, which has a beneficial effect on the quality of the seam.

The welding of film panels can be done in two ways.

Superglue is also useful for repairing finished film coatings. The way to use it in this case is as follows. Using a brush or stick, apply a thin layer of adhesive around the damaged area from the outside of the film. Let it dry for 2 hours. Then cut out a patch of the required size from the film, attach it to the damaged area and smooth it well. Even old film can be glued with superglue. However, you should know that it is best to repair the film coating in sunny weather.
