Polyester Film Transparent Shrink Film Protective Film Glass Protection PET

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 and toughness are the best among all thermoplastics, and its tensile strength and impact strength are much higher than 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.
