What is the role of PET film?

Feb 09,2022

PET film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties and dimensional stability, transparency, recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, optical grade mirrors surface protection, etc.

With the development of special functional films, new uses of polyester films are also emerging. Can be produced into mobile phone LCD protective film, LCD TV protective film, mobile phone keys and so on.

PET film is a kind of packaging film with comprehensive performance. It has good transparency and gloss; good air tightness and fragrance retention; moderate moisture resistance, and the moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, its strength is the best among all thermoplastics, and its tensile strength and impact strength are much higher than those of ordinary films; and it has good strength and stable dimensions, suitable for secondary processing such as printing and paper bags. . PET film also has excellent heat and cold resistance and good chemical and oil resistance. However, it is not resistant to strong alkali; it is easy to carry static electricity, and there is no appropriate anti-static method, so attention should be paid when packaging powdered items.
