What are the types of protective film

There are many types of protective films. According to the material, the commonly used ones are: PE (polyethylene), PET (ester film), CPP (polypropylene), PVC (polyvinyl chloride), OPP, etc. There are many colors of PE. , Z commonly used are transparent, blue, black and white, milk 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 frosted film with a fog-like effect, PVC is usually transparent, and blue transparent electrostatic film, OPP is generally a transparent film with adhesive, PE is the most types of protective films, and it is divided into PE glue Film, PE electrostatic film, PE textured film, PE stretch film, PE packaging film, viscosity from 5g-270g, thickness from 1.5C-15C. Z commonly used is 5C. PET, acrylic adhesive PET, frosted PET, three-layer PET, single-layer PET, double-layer PET, PET release film. PET protective film is usually used for various screen protections, and PET release film is often used for punching PET protective film in die-cutting factories. The commonly used types of punch Z 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 plain weave or reticulated film. The rougher the surface, the higher the viscosity of the protective film. General screen protection choose PET protective film, all kinds of plastic products and sheets, glass surface protection choose PE film, high-gloss plastic surface can use electrostatic film, frosted film, low-viscosity PE film.
