What is PE self-adhesive film? Is it the same as PE electrostatic film? How to distinguish between self-adhesive film and electrostatic film? In fact, people in the industry usually raise such questions. They think that self-adhesive membranes are different from electrostatic membranes. Think of self-mucosa as self-mucosa. In fact, the electrostatic film is an electrostatic film, and the two have nothing to do with each other. In the protective film industry, the self-adhesive film is actually an electrostatic film, and the two are just called differently. Because the electrostatic film is self-adhesive without glue, it is also called self-adhesive film in some occasions, and the application method is the same as that of PE electrostatic film.
In the protective film industry, according to the classification of the viscous material of the protective film, it can be divided into glue type protective film and self-adhesive protective film. Each has its own advantages and disadvantages. Self-adhesive protective film is mainly used for products with higher appearance quality. Such protective films are generally multi-layer co-extrusion molding, and the film of one layer is made of self-adhesive materials, so that it can be self-adhesive without coating glue. There are many self-adhesive materials, usually EVA or other modified materials are used for electrostatic film. The principle of electrostatic self-adhesion is actually because the self-adhesive material is a high polymer with low crystallinity. There are a lot of exposed molecular chains on the surface of the film. These molecular chains can easily fill the pores on the surface of the object to be adhered to each other.
