What are the characteristics of a single-layer PET protective film?

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 and polyethylene terephthalate as the raw material. It is made into a thick sheet by an extrusion method, and then a film material 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 types 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 material and waste discharge;
3. The surface resistance is 107-109Ωcm, environmentally friendly, non-toxic and tasteless;
4. Processed in a Class 1000 clean environment, with excellent cleanliness;
5. Low viscosity, little change in adhesion with time after being attached;
6. Excellent anti-static effect, long-lasting and stable performance.
7. The product has single-sided anti-static and double-sided anti-static peeling voltage.
8. The transparency is excellent, and the visual inspection of the optical film can be carried out in the state of laminating the protective material;
9. No electrostatic material migration phenomenon on the surface of the product;
10. It 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 good adhesive strength and good retention for metal, plastic, glass and other objects to be attached;


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 layers of structure can be selected.
