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 mirror surface protection and other fields.

PET film is a kind of packaging film with relatively comprehensive performance. Its transparency is good and shiny; It has good air tightness and fragrance retention; Medium moisture resistance, moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, its strength and toughness are the best among all thermoplastics, and the tensile strength and impact strength are much higher than that of general films; And good stiffness, stable size, suitable for printing, paper bags and other secondary processing. PET film also has excellent heat resistance, cold resistance, and good chemical and oil resistance. However, it is not resistant to strong alkalis; Easy to carry static electricity, there is no appropriate anti-static method, so it should be paid attention to when packaging powdered items.
