PET film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability. It can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, and optical mirrors. Surface protection and other fields.
PET film is a more comprehensive packaging film. It has good transparency and luster; it has good air tightness and fragrance retention; it has medium moisture resistance, and its moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, and its toughness is the best among all thermoplastics. Its tensile strength and impact strength are much higher than ordinary films; it has good stiffness and stable dimensions, and is suitable for secondary processing such as printing and paper bags. .
PET film also has excellent heat resistance, cold resistance and good chemical resistance and oil resistance. But it is not resistant to strong alkali; it is easy to be charged with static electricity, and there is no proper anti-static method, so attention should be paid when packing powdery articles.
