PET protective film is usually classified according to the structure and can be divided into double-layer PET protective film, three-layer pet protective film, single-layer pet protective film and so on. Before we introduced the characteristics of the double-layer PET protective film, what are the characteristics of the single-layer PET protective film?
The single-layer PET protective film is made of polyester film (PET) as the base material, polyethylene terephthalate as the raw material, made into thick sheets by extrusion, and then made by biaxial stretching; Coated with silica gel water on one side to form a single-layer PET protective film.
Features of single-layer PET protective film:
1, there are many kinds of viscosity and thickness, and the surface of the protective film is smooth and flat;
2, suitable for round knife die-cutting, flat knife die-cutting punching mat and waste;
3, surface resistance 107-109Ωcm, environmentally friendly, non-toxic and tasteless;
4, 1000 grade clean environment processing, excellent cleanliness;
5, low viscosity, little change in adhesion over time after attachment;
6, excellent anti-static effect, durable and stable performance.
7, the product has single-sided anti-static and double-sided anti-static peeling voltage.
8, excellent transparency, the appearance of the optical film can be inspected in the state of laminating the protective material;
9, no electrostatic material migration phenomenon on the product surface;
10, can also be used as an auxiliary die-cutting of high-clean optical materials;
11, good heat resistance, weather resistance, and acid resistance;
12, this product has very good adhesive strength and good retention for metal, plastic, glass and other substrates;
Pet protective film is mainly used in digital product protective film, automobile protective film, food preservation protective film, etc. For industrial applications, protective films with different layer structures can be selected
