Is it possible to glue polyethylene
When installing waterproofing or a greenhouse, it is often necessary to glue several pieces of polyethylene together in order to obtain a film of the desired size. But how to glue a plastic film, and is it possible to do this at home?
The question is not as simple as it seems at first. It is also known from the school chemistry course: the higher the polarity of the polymer material, the better it lends itself to gluing. The polyethylene molecule, written in chemical symbols, is very similar to a long chain consisting of identical units - CH2-. This uniformity suggests that the electric charges inside the polyethylene molecule are distributed evenly, i.e. it is non-polar. Therefore, polyethylene sticks together very poorly.
Welding of a polymer film: a - using an electric soldering iron; b - using a run-in for an electric iron; c - open flame.
Very often, adhesive mixtures are used for bonding polymeric materials, which are prepared from the same materials (or similar ones) dissolved in a suitable solvent. But this will not work with polyethylene - it practically does not dissolve in organic solvents.
Some polymers can be glued simply because they have a rough surface. In this case, the adhesive solution fills the irregularities and, while solidifying, clings to them, tightly gluing pieces of material. But with polyethylene, this will not work, because it has a perfectly smooth surface.
Therefore, if we talk specifically about the gluing process, then gluing a plastic film at home is almost impossible. Yes, and in industrial it has never been glued until now.
But although pieces of polyethylene cannot be glued together, they can be welded, or, more precisely, soldered, which has been successfully done for many years in industry, having developed many methods for such welding.
. But of this many ways, there are only two that can be applied at home.
Welding of polyethylene pipes technology of butt and electrofusion soldering
The reliability and proper functioning of a plastic pipeline (especially if it is pressure) directly depends on the method of connecting the pipes of which it consists. The most durable way is, of course, welding of polyethylene pipes. With its help, you can connect the elements of the pipeline not only among themselves, but also with fittings. Its technology will be discussed in our article.
The welder performs the installation
Electrofusion welding
Another method of welding pipes made of polyethylene is also known - installation using electric couplings (it is also called thermistor welding). The main positive characteristics of electrofusion welding are high-quality connection of pipeline elements and a simple, quick installation process. With its help, unlike butt welding, it is possible to connect pipes with a wall thickness of 4 mm or less.
Instructions for welding using electric couplings involves the following steps:
- Cleaning the ends from dust and dirt for a length of ? coupling length or even more - produced mechanically.
- Degreasing surfaces, removing the oxide layer.
Set of equipment for electrofusion welding
- Mounting the coupling on the pipe, centering.
- Welding connection of the coupling and the end of the pipe, a welding machine for polyethylene pipes is used.
- Cooling of the joint - occurs naturally, the seam should not have any extraneous influence.
Soldering of polyethylene pipes and fittings can be carried out by welding machines with different degrees of automation.Depending on the conscientiousness of a particular manufacturer, the build quality of the equipment itself and its ability to work in different conditions may differ.
Electrofusion soldering process
The welding machine for socket welding is very convenient in operation, equipped with a scanner that reads information from the bar code located on the fitting (welding time, voltage, temperature, etc.). Based on the data received, the unit itself sets the welding parameters, automatically performs the task, controls all stages and, in case of an error, notifies the operator by displaying its digital designation on the screen.
Classification of package welders
Manual bag sealer
It is an inexpensive and versatile device. It is used at home and in production, where it is not necessary to pack large volumes of products, and also where speed is not important. Manual sealers of packages can be floor and desktop.
Automatic sealer
Used in large stores, supermarkets for high-speed packaging of goods, clothing, food. If a manual bag sealer requires control and a constant presence of a person nearby, an automatic sealer works at the touch of a button.
Advantages of automatic sealers:
- The heating elements are hidden inside the body, so there is no risk of body parts or foreign objects getting in. The necessary thing in the package is brought to the sealer, inserted into the opening for the neck. After pressing the button, sealing occurs within 3 seconds.
- You do not need to align the film yourself so that it packs evenly. The instrument is set to do this automatically.
- Ready-made bags with a clip look neat and airtight.
Impulse bag sealers
Impulse sealer
It is a hand-held, lightweight and compact device with a plastic housing. It is used for sealing polypropylene or polyethylene up to 150 microns thick, up to 40 cm wide. The width of the finished sealed seam is 3 mm, and its length is 400 mm. The machine is not equipped with an automatic film cutting system.
The principle of operation is pulsed heating of the elements during soldering when the film contacts the bar. The timer sets the sealing time (from 1 to 5 s), the melting temperature and its density. Products are laid out on the heating surface, the lid is closed, power is turned on and the surface is heated. At the end of the process, the power is turned off.
Sealers with constant heating
The device is used for large volumes of products and high speed sealing. The package includes 2 sponges that cling to the products and a thermal knife that separates the packages from each other. Sponges are heated to the required temperature using a heating element built into them.
Roller conveyor sealer
The equipment is used for sealing polyethylene with a density of up to 800 microns, of any length. The device works with different types of polymeric materials, in two positions - vertical and horizontal. Products are placed on a conveyor belt, moving along it to the departments of sealing, cooling and engraving. The device allows you to adjust the speed of movement along the conveyor, the temperature of the heating surface and the dating system.
Vacuum sealer
The device for gluing a polyethylene film itself draws air from the package, creating a vacuum and tightness in it. To do this, press the "Vacuum" button. The device is used to pack food, preventing the spread of bacteria, so that the food lasts longer.
mini sealer
Vacuum mini bag sealer
This plastic device weighing up to 100 g, up to 10 cm long, is powered by two 3 W batteries. For soldering, you need to put the package on the thermal contact, lower the lever and drag it along the entire length of the package.When the lever touches the package, the power will automatically turn on, the surface will be heated, and the layers will be soldered. The instrument will automatically insert the bag clips.
Ticks
Packs packages with a density up to 200 microns. The manual clipper for packages allows you to clip goods in bulk. The device is mains operated and looks like an apparatus with two handles that are connected to Teflon heating surfaces.
Polyethylene welding
The strongest seam is obtained by welding polyethylene.
If done correctly. The fact is that polyethylene is molded hot, usually under very high pressure, which reaches hundreds of kilograms per square centimeter. And when it is reheated at atmospheric pressure until melting, it tends to shrink, a little, but this is enough to make it difficult to weld. Two types of welding can be distinguished: film welding and welding of thick polyethylene (canisters, pipes, etc.)
To weld the film, heated objects or a special apparatus for gluing polyethylene, or rather, welding, are used. It works like this: both layers of film are pulled over a heated wedge, and then immediately welded with a pair of compressed rollers. With the right selection of temperature and pressure of the rollers, an excellent result is obtained - complete tightness of the seam.
But with a little practice, you can learn to glue polyethylene even with an electric soldering iron or iron through paper so as not to spoil its sole. The clean edges of the film are superimposed on each other and the edge of the sole of a heated iron is led through the paper.
Gluing thick polyethylene is more difficult, and good skill is required here. The best heating method is a gas portable burner (it is convenient to work with), or a hair dryer with a nozzle for a narrow jet of +250°C.
The course of action may be as follows:
- Thoroughly clean and dry surfaces before welding.
- Prepare polyethylene filler for the seam. It is best to take a narrow piece of the same material.
- Heat the edges of the seam before melting, let them “settle” a little. But do not get involved in this process.
- Start introducing the additive (see item 2), fusing it evenly into both sides of the seam to a thickness equal to the material.
- Let the seam cool completely.
The same method is applicable when deciding how to glue polyethylene foam. The surface of polyethylene foam is not very conducive to bonding, and it is better to weld it carefully.
Another way to weld thick polyethylene, see the video:

general information
Any do-it-yourself welding of plastic pipes depends on the type of plastic used for it. There are three main types of plastic materials:
- polyvinyl chloride products used as a cheap type of plastic in order to reduce the cost of repairing pipelines;
- polyethylene materials used both inside buildings and as external pipelines capable of withstanding negative ambient temperatures and high water pressure inside them;
- products containing metal (metal-plastic), which are particularly reliable and durable, serving for more than 50 years and used for the basis of pipelines with hot water supply.
Gluing with acrylate glue with filler
The best adhesive is Weicon Easy-Mix PE-PP. It is specially designed for materials with poor adhesion. Most liquids "stick" to polyethylene very poorly, and are simply squeezed out from the point of contact of the surfaces.
But in this glue there is an additive of tiny glass beads, which does not allow the glue to leave the place of gluing, forming a gap of the required thickness. Therefore, the bonding surface is sufficient and the adhesive, when solidified, holds the surfaces together firmly. It is difficult to find better than gluing polyethylene.
Surfaces must be thoroughly degreased and dried before bonding. Adhesive can only be supplied from the branded packaging mixer. The best temperature for work is +21…+23 °С. Glue in a liquid state is suitable for no more than 2-3 minutes. Having applied a layer, it is necessary to join the surfaces immediately. The complete readiness of the seam (the highest mechanical strength) for polyethylene will be achieved in a few hours (4-5 according to the experience of working with glue). Exposure of the adhesive joint is carried out at a temperature of +15 to +70 degrees.
How to solder plastic film at home
How to solder plastic film? And even at home? Yes Yes Yes!!! Even our hardworking female hands can easily do this.
How wonderful to be a needlewoman! Perhaps each of you will say this. Difficult situations for someone are usually not a problem for us.
Take, for example, the covers for textbooks for our children, which is relevant at the beginning of the school year. There will definitely not be enough cover of the required format for one of them, even if you go around the whole world. Not a problem - we solder ourselves!
Dad is at work, and mom can easily do not dusty, but a little smoky work with the help of a burner.
For those who have never soldered a film, I will say that this is the case:
- simple and does not require super skill,
- allows you to make the product as you wish,
- saves money - materials are available,
- within the power of any woman.
In order to solder the film at home, you need the following TOOLS and DEVICES:
Soldering iron, soldering iron or burner - your choice. Be careful - the tool gets very hot, so keep your kids away while working! Don't forget about yourself too. Ventilate the room, as during operation the film melts and emits very acrid smoke.
Metal ruler. The heater is in constant contact with the ruler during film soldering. Do you understand why our ruler is old and NOT wooden?
The substrate for the work is glass or a wooden board. Ordinary glass can break from high temperatures. My choice leans towards a wooden plank.
So, the main MATERIAL is a polyethylene film of any thickness and color. Many improvised materials can be used as raw materials for work:
- ready files for folders,
- new plastic film
- covers for school textbooks and notebooks (new or old).
It is IMPORTANT to start training and the work itself on a test piece of polyethylene film! IMPORTANT to work in a well-ventilated area!
Everything is ready - GET TO WORK! Everything is done in just a few steps.
STEP 1 We take a film of a certain size and fold it in the desired form. Consider the place of the seam - this is the junction of the two layers of the film.
STEP 2 Place the ruler on two layers of film and firmly press it with the fingers of your left hand to the surface of the substrate.
STEP 3 With the soldering iron already heated, draw along the edge of the ruler. Do not rush - the movement of the hand is slow, because at this moment two layers of film are soldering.
So you soldered the plastic film at home.
Let's solidify the knowledge. Observe two conditions when working - press the ruler tightly and slowly lead the soldering iron - the seam will be even and relatively strong.
Where in the economy can we apply the acquired knowledge? What can be made from film? Let's do:
- covers for books, magazines and notebooks,
- small sachets,
- solder documents, certificates (something similar to lamination).
SOME EXAMPLES FROM LIFE.
For many years of doing needlework, a large number of books and magazines have accumulated at home. In my creative library there are editions of 1960-70s, I inherited something.
You understand that if you do not take care of printed editions, then gradually the covers can become dilapidated and lose their novelty. Homemade covers for them were made in a few evenings.
I think now both my children and grandchildren will use these books and magazines.
Here you see covers made of film for notebooks and non-standard educational literature.
PACKAGES for patterns and all sorts of little things
For any needlewoman, patterns of artificial flowers and all sorts of little things are “bread”. A little time can be spent on sorting these parts, then on making bags, and you will always have order in the needlework corner.
In the same way, we can put things in order in patterns.
Home LAMINATION for documents
Every document loves neatness. If you seal it in a film, it will be stored for many years.
I soldered the film myself - saved on lamination!
I hasten to please you, you will learn how to solder a film at home very quickly. And then, beware! When you get at least one quality seam, you will urgently want to put your knowledge into practice. “This must be soldered and this, and this is also a must!”.
But if it's no joke, then the ability to solder the film is not carried behind your back in a backpack, and there will always be many cases of using it in everyday life.
Good luck and see you next time on the blog. Irina Timoshek.
Fellow needlewomen and needlewomen, have you ever soldered the film yourself at home?
Open flame welding of polyethylene
To reconcile polyethylene in this way, you will need:
- metal or ceramic bars;
- a tool for welding (this can be a gas burner, a blowtorch, a spirit lamp, and in the absence of these, you can use a torch or even ordinary matches).
Electrical circuit diagram for connecting the "ironing" to the network: 1 - constant wire resistor; 2 - metal case; 3 - sting-horse; 4 - textolite handle; 5 - stand.
The edges of the films to be welded must be fixed with metal or ceramic bars (wooden ones are not suitable for this purpose). It is necessary to fix it in such a way that a narrow strip of film (3-5 mm, no more) is visible from under them at the place of welding. The bars are needed not only to fix the film, but mainly in order to quickly remove heat from the films being welded, otherwise they will burn out entirely instead of melting.
Next, you need to hold the flame along the remaining open edge. The flame speed will also have to be selected empirically, especially since it will be different not only for each brand of polyethylene, but also for each tool too. If the operation is performed correctly, then upon its completion a dense roller is formed, firmly connecting the two edges of the plastic film.
As an alternative to welding, when constructing greenhouses and greenhouses, two pieces of polyethylene film can be sewn together. To do this, two pieces of film are overlapped on top of each other. The overlap should be 2-2.5 cm.Then, a regular medical patch is glued to the overlap on both sides. It will not hold well, but it's not scary, the main thing is that the strips of the patch lie exactly at the place of overlap one above the other.
Then, over the overlap, two seams are made with large stitches. In this case, the pieces of the film are fastened with the help of stitched threads, and the patch, having a stronger material structure, prevents the threads from tearing the polyethylene. However, this method is not suitable for waterproofing, since the seams will let moisture through.
If it becomes necessary to glue the film to some other material, then you will have to look for a transparent film from another material that sticks better, and for which there are special adhesives on sale. Alternatively, it may be a PVC film.
Connect the plastic film in the ways described or look for something new, it's up to you. The main thing is not to be afraid to experiment, because if something cannot be done today, this does not mean at all that it cannot be done tomorrow or the day after tomorrow.
Methods and methods for welding polyethylene film
Welding of polyethylene is a process of connecting individual sections of a material by heating to a melting point and compressing the layers.
When the film surfaces are melted, the layers are connected at the molecular level, the result of this procedure is a welding seam. In order for the quality of the seam to be high and it to be as strong and reliable as possible, it is necessary to choose good equipment, strictly follow the welding technology and not make a mistake with the heating temperature. This indicator should vary between 130-160 ° C.
That is why welding of a polyethylene film must be carried out with strict observance of a number of conditions:
pieces of materials belonging to the same production batch should be welded, it is important to choose the right temperature regime, if it is below the norm, then the strength will be low, if the specified temperature indicators are exceeded, the joint may deform, another prerequisite is clean surfaces to be joined. Also, the welding machine affects the success of the work and the quality of the seam.
It is important not only to choose the right device for film welding, but also to be able to handle it.
Also, the welding machine affects the success of the work and the quality of the seam.
It is important not only to choose the right device for film welding, but also to be able to handle it.
Hot welding of polyethylene
Welding the film using an electric soldering iron: a - type of seam; b - device of an electric soldering iron for welding the film.
The most convenient way to do this operation is with a metal roller with a heating device inside. But to make such a device at home, you need to have a fairly high qualification of an electrician.
Therefore, people's ingenuity found a completely satisfactory replacement for such a tool - an ordinary iron. Since polyethylene film of different grades melts at different temperatures, no specific recommendations on the temperature regime of welding can be given.
The temperature of the heating iron for welding will have to be determined by trial and error. If the temperature of the iron is insufficient, then the film will not boil, but if the iron is heated too much, the seam will turn out to be “overcooked”, weak, and the film on the sides of the seam will be easily torn. The only thing that can be advised initially is that the iron should not be too hot.
The soldering technology itself is very simple. To make the seam neat and even, soldering is best done on a flat wooden surface. The edges of the film must be laid on this surface with a slight overlap on each other (0.5-1 cm). On this overlap, you need to draw a spout or edge of a heated iron. The passage should be no more than a second in one place, otherwise you will burn the film.
PVC film can be recognized by the yellowish tint of the edge of the roll.
But with this method of soldering, there is one very important negative point: the heated plastic film very often sticks to the iron. To prevent this from happening, it is better to cover the polyethylene seam with a thin sheet of cellophane before soldering, and then go over it with an iron.
The strength of the solder can be checked by simply pulling the soldered pieces in different directions. If the seam diverges, it means that the soldering quality is unsatisfactory, and you need to repeat everything from the very beginning. Some craftsmen perform this soldering not with an iron, but with a hot knife blade, claiming that it is more convenient for them. But this is a matter of taste.
Types of polyethylene compound
The most simple and low-cost method for joining polymeric materials is the so-called resistance welding of polyethylene.
In this way, reliable connections are formed, which are preserved during subsequent operation.
To perform , the joined edges of the polymers are heated with "hot air" or "hot wedge" until they melt. Compression and seam formation is carried out by roller elements specially designed for clamping. The resulting seam will be single or double, it has good strength.
The method called "hot air" is a heated stream of air, with which the polymer softens and melts. For the same purpose, a heating part made of metal is used - a “hot wedge”. Contact of elements and polymer is carried out both from the outside and from the inside, and good strong seams are formed.
In addition to the contact method of connection, extrusion welding can also be used. When choosing this method, the molten polymer is supplied under pressure, the surfaces connected to each other change from dense to ductile, and squeezing helps to hold them together.
Butt soldering of polyethylene pipes and with the help of an electric coupling
Plastic-based pipes are an excellent replacement for steel, concrete and others in the construction of sewer and gas pipelines. Soldering polyethylene pipes is used to obtain a high-quality one-piece transport system.
Usually soldering is carried out by butt or electrofusion method. Both technologies share a common physical principle. It is based on the action of interpenetration of molecules from two surfaces of PE or PVC products to be joined. However, there are some significant differences between the two technologies. In order to reveal more widely all the features of butt and electrofusion welding, we will consider them separately.
Butt brazing technology for polyethylene pipes
Butt soldering is most in demand during the installation of pressure pipelines, sewers and gas pipelines. In order for welded joints to meet strength characteristics, at the preliminary stage, the conditions for joining welded elements should be met:
- pipes can be installed if they are made of the same material;
- welded pipes must have smooth and clean end surfaces;
- soldering is carried out with strict alignment of PE pipes using a centralizer.
Going directly to welding, it is necessary to take into account the temperature regime of the process
At this stage of installation work, the fact that polyethylene, PVC, and other similar plastics have a significant degree of linear and volume expansion when heated is taken into account.
Rapid heating leads to uneven temperature distribution with the formation of large pressure drops at adjacent points of the joint zone, which can cause undesirable stress concentrations inside the seam.
Further technology for soldering PE pipes is reduced to the following operations:
- With the help of a heating element, which is installed between the pipes to be welded, the ends begin to heat up, taking into account the specified temperature regime: HDPE pipes - up to 220 ° C, LDPE pipes - up to 200 ° C. The ends are brought to the heater manually. Then, using a hydraulic clamp, they are securely attached to the thermoelement under a pressure of 0.6-0.8 kgf/cm².
- Having endured the necessary time, the pipes are moved apart, the heater is removed, and the ends of the pipes are connected under a pressure of 1.0-2.0 kgf / cm², depending on the brand of polyethylene.
- The last operation - cooling the seam, occurs naturally when the pressure is maintained for a certain time.
- At the end of the technology, the strength of the welded joint, its size and bead configuration are checked. After removing the pipe from the clamps, the seam is marked by assigning a serial number to it.
The soldering of pipes throughout the process is constantly controlled by pressure and time. Change and reconciliation of these parameters occurs according to the cyclogram.
Electrofusion soldering of pipes
Electrofusion soldering of polyethylene pipes is used when the pipes have different wall thicknesses. Scope of application: low-pressure pipelines (drainage, gravity sewerage), tie-in into an already laid pipeline, repair and replacement of elements. The main difference between a coupling joint and a butt joint is a better soldering of pipes with a significant difference in their diameters.
Another advantage of such soldering is the speed, ease of operation and the ability to carry out them in small areas. The principle of welding using electric couplings is to melt the ends of the pipes with an embedded metal spiral, and the technology of this process looks like this:
- the ends of HDPE or LDPE pipes are cleaned of dirt and degreased;
- an electric coupling is put on one of the ends of the pipe and clamped with a positioner;
- after aligning the ends of the pipes, the coupling is shifted back so that the junction is exactly in its middle;
- operating voltage is applied to the terminals of the electric coupling, the heating process is carried out automatically;
- soldering is considered complete according to the indications of the fitting holes, from which molten polyethylene should appear;
- cooling of the seam should take place without forced cooling in a state of complete immobility.
Plastic PE and PVC pipes are confidently replacing metal pipes in everyday life and industry.
This happens due to the fact that they often surpass the latter in such characteristics as the chemical inertness of the material, relatively easy installation, ease of maintenance, slight local resistance in the line, and a long warranty period (up to 50 years).
With regard to technology, it should be noted that the soldering of PE pipes involves a significant degree of culture of installation work and a good knowledge of the subject. This issue can be solved by training specialists on the basis of specialized educational institutions.
Soldering polyethylene bags
A bag sealer is a special type of equipment used to solder films and ready-made plastic bags, as well as to produce bags from any film material and polymers with the addition of polypropylene.
Today, the modern market offers various types of devices that can be equipped with pulsed or constant heating, be of a desktop or floor type, have a pedal drive, and also be automatic or manual.
So, for example, for packing products with a short shelf life, you can use an apparatus that has a function in its equipment that allows you to put a date on a plastic film.
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.
Xylene and trichlorethylene heated to 70-75°C can also be used for film bonding. At a temperature of 30 ° C, film panels can be glued together with 80% acetic acid
If you have chosen one of the above substances to join the film parts, use extreme caution 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. PK-5 glue is best suited for joining polyamide film panels. 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 sale, which is designed specifically for plastic film. It gives a very strong, waterproof and elastic bond. In addition, it is absolutely odorless, and the compounds are transparent and almost invisible. With one bottle of glue with a capacity of 50 ml, it is possible to glue a seam 15 - 20 m long.
Since Super Glue contains household solvents, it is recommended that you follow the same precautions when handling it as when using household chemicals. When stored in sealed packaging, the shelf life of the adhesive 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 the finished film coating. The method of its application in this case is as follows. Use a brush or stick to apply a thin layer of adhesive around the damaged area on the outside of the film cover. 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 them on top of each other. Stitch infrequently. To increase the strength of the seam, make a paper gasket. This method of connecting film webs is most often used if it is necessary to patch the film coating before it is stretched onto the frame or when an already stretched film is torn. Minor damage to the film can be sealed with adhesive tape.
This problem is often faced by owners of summer cottages, greenhouses, home craftsmen, and even car owners. After failures, people start looking for information on the topic. Is it possible to glue polyethylene at all? In the article you will find the answer to this question.
Conclusion
In the case of high strength requirements, welding should certainly be preferred. If welding is still accompanied by keeping the seam warm at about seventy degrees for several hours with slow cooling, then the seam will have a slight brittleness. The abrupt cooling of the seam makes it brittle, especially in cold conditions.
Filled acrylate glue does not require mechanical surface preparation, except for unconditional cleaning and degreasing, which must always be done before gluing. You can even try experimenting with other acrylate adhesives by adding powdered chalk or cement to them. It is possible that you will be able to get a high-quality and very inexpensive recipe.
Epoxy glue is the most difficult to use, and the strength here is not the highest. But in extreme cases, and this can be a way out.
In construction, polyethylene film is mainly used as a waterproofing or heat insulator, when it comes to film greenhouses. It has polyethylene and certain soundproofing properties, but not enough to be used as an independent soundproofing.
To glue polyethylene, you must first purchase the kind of glue that is used for gluing plastic.
