PET polyester film refers to a film made by biaxially stretching a polyethylene terephthalate polymer in the polyester family. Optical grade PET polyester film has high light transmittance, low haze, high brightness, no yellowing, good adhesion, good flatness, no dark and dark lines, high temperature and ultraviolet radiation, good stiffness, anti-sintering, and easy to break. Features such as damage have been widely used in recent years. In particular, the raw materials and auxiliary materials that are indispensable in the field of LCD production, such as liquid crystal display, can use at least 7~8 PET optical films with different functions. These functional PET optical films are mainly used in PET. The surface of the polyester film is coated with various functional coatings. Therefore, the development of various functional coatings for PET-type optical films in the field of liquid crystal display is one of the important directions in optical film research.
