There are many varieties of protective films, commonly used according to raw material points are: PE (polyethylene), PET (polyethylene). Ester film), CPP (polypropylene), PVC (polyvinyl chloride), OPP, etc.,
There are many colors of PE, commonly used are bright colors, blue, black and white, milky white, in addition to black, gray, green, yellow, orange, gold, red and so on.
The colors of PET are generally transparent, gray, and gold.
CPP is usually a frosty foggy film,
PVC is common bright, and blue bright electrostatic film,
OPP - usually clear film,
PE is a variety of protective films, divided into PE film, PE electrostatic film, PE mesh film, PE stretch film, PE coating, viscosity from 5G-270g, thickness from 1.5C-15C. The most commonly used is 5C.
PET protective film includes silicone PET, acrylic PET, frosted PET, three-layer PET, single-layer PET, double-layer PET, and PET release film. PET protective film is commonly used for all kinds of screen maintenance,
PET release film is often used for punching PET protective film in die-cutting factories. The commonly used punching types are 5C and 7.5C, and the commonly used release films are 2.5C, 3.8C, 5C, and 7.5C.
Generally, products with smooth surface can choose electrostatic film, low-viscosity PE flat film or mesh film. The rougher the surface, the greater the viscosity of the protective film.
Generally, PET protective film is used for screen maintenance, and various plastic products and plates are used. PE film is used for glass plate maintenance. Electrostatic film, frosted film, and low-viscosity PE film can be used for high-gloss plastic surfaces.
