How is made laminating film

How is made laminating film

As already known, the basic material for the production of film base are PET, PP and PVC. If you decipher the abbreviations, we can understand that it is polyester, polypropylene, and polyvinyl chloride. In rare cases, the base film is made of polycarbonate or nylon.

Polyvinyl chloride is known for its flexibility and relatively low melting point. The elasticity of the material allows manufacturers to produce a film with a variety of textures, "sand", "canvas", "skin" and many others. The product, a laminated vinyl film, you can easily bend, twist or crush.

Polyvinyl chloride is not afraid to scoring, but the process of laminating vinyl film is quite simple and will not bring any surprises. PVC film protects the product from getting it to ultraviolet rays, so it is much more expensive than polyester or polypropylene. Such a film is used most frequently for laminating photographs.

Despite that the polypropylene film is a bit cheaper, while it is quite good quality and practical. Due to its flexibility, the film does not curl at its sole lamination, and very well tolerated by the process of scoring. It has wildly popular among manufacturers of lottery products.

A film based on polyester (PET) is a universal. It has the advantage over other types of films due to its transparency, but gives them flexibility. Another advantage of this type is its low cost, which makes it possible to use this film, those who have a limited budget. Typically, such film is used for the sliding and roll lamination.

The intermediate layer between the substrate and the adhesive in many inexpensive films consists of polyethylene (PE). But at higher quality and more expensive films of vinyl. For example, there are film, and an intermediate adhesive layer, which are made of etinelvinilatsetata (EVA), i.e. how much more vinyl content in the adhesive layer, the melting point is lower, which lowers the temperature of the laminating film.

Furthermore, the vinyl content also affects the transparency, adhesive capacity, and of course on the cost of the film. As the intermediate layer using H-EVA.
