There are many types of protective films, which are commonly used according to materials: PE (polyethylene), PET (ester film), CPP (polypropylene), PVC (polyvinyl chloride), OPP, etc.

   PE has many colors, the most commonly used are transparent, blue, black and white, milk white, in addition to black, gray, green, yellow, orange, gold, red and so on. The color of PET is generally transparent, gray, and gold. CPP is usually a matte, foggy film, PVC is generally transparent, and blue transparent electrostatic film, OPP is generally transparent with a film,

   PE is the most common type of protective film, which is divided into PE film, PE film, PE film, PE film, PE film, viscosity from 5g-270g, thickness from 1.5C-15C. The most common is 5C.

   PET, acrylic adhesive PET, frosted PET, three-layer PET, single-layer PET, double-layer PET, PET release film. PET protective films are commonly used as a variety of screen protectors, and PET release films are commonly used in the die protection of PET film. The most commonly used punching type is 5C and 7.5C. The commonly used release film is 2.5C, 3.8C, 5C, 7.5C.

   Generally, the smooth surface of the product can choose electrostatic film, low-viscosity PE plain or textured film, the rougher the surface, the greater the viscosity of the protective film. General screen protection chooses PET protective film, all kinds of plastic products and plates, glass surface protection chooses PE film, high-gloss plastic surface can use electrostatic film, matte film, low-viscosity PE film.
