It is a packaging film with relatively comprehensive performance. It has good transparency and gloss; it has good air tightness and fragrance retention; it has medium moisture resistance, and its moisture permeability decreases at low temperatures. The mechanical properties of PET film are excellent, and its toughness is the best among all thermoplastics. Its tensile strength and impact strength are much higher than those of ordinary films; it has good strength 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. However, it is not resistant to strong alkali; it is easy to carry static electricity, and there is no appropriate anti-static method, so it should be paid attention to when packaging powdery items.
