It was necessary to carry out repair work on a plastic film, because it was torn or deformed, but out of ignorance you cannot and continue to postpone your project? Do not rush, below we will analyze several practical welding methods available to most readers.

The nuances of welding

Polyethylene film is used to solve various household problems:

  • greenhouse warming;
  • give windows additional insulation;
  • car protection – raw materials for awnings;
  • packaging bags, etc.

If integrity is lost, the hardware will become ineffective. Therefore, the elimination of damage will significantly save the budget and extend the service life of the product.

Welding characteristics:

  • only materials with identical characteristics are assembled: density, thickness, texture;
  • minimum edge shrinkage – not less than 5 mm;
  • pre-cleaning of the polyethylene surface is necessary.

The principle of bonding consists in heating the film. When the desired temperature parameter is reached, the two edges are fixed together and form a complete material.

At home, the best option would be to solder in two popular ways:

  • use a standard soldering iron;
  • using an iron.

Let’s look at each method in more detail.

Soldering with a soldering iron

Any 40W to 60W soldering tool will do. For successful repair work, it will need to be slightly improved:

  • dismantle the end of the radiator (sting);
  • prepare an aluminum (or copper) plate, fix it in a premade hole (box);
  • the structure is reinforced with a rivet or screw;
  • processing and rounding are carried out using a needle file.

When the tool is prepared, you can equip the workplace. For this you will need the following items: a flat and wide table, a kindling made of wood. Welding is carried out in the following order:

  • polyethylene is cleaned of dust, dirt, grease;
  • a wooden blank is placed under the material;
  • the level of the angle of inclination is approximately 45º;
  • the hot end of the tool should be run smoothly (without sudden movements) on the surface to be treated.

If the house has a burner, it can replace a soldering iron, since the principle of operation of the devices is identical. The sequence of actions will be in the order shown above.

Solder with a standard iron

Any iron with adjustable heat will work. The process will require a minimum temperature of the device, about 120ºС.

The main nuance of good workmanship is the instant cooling of the resulting seam; for this it is necessary to prepare a damp cloth in advance.

The work surface is no different from the previous method, you will need: a table, a block of wood.

Spike performs in order:

  • degreasing of polyethylene;
  • the edges of the film overlap;
  • a blank sheet of paper is superimposed on polyethylene;
  • the required temperature regime on the iron is set;
  • the device should be drawn slowly over a sheet of paper, firmly pressing both films against each other;
  • it is important to quickly cool the resulting seam;
  • the process is complete, the product can be used.

For dense textures, it is recommended to perform this procedure several times.

Using a minimum of materials and simple devices, you can easily restore the second life of a polyethylene film, and it will perform its functions for a long time.
