PET film is a kind of comprehensive packaging film. Its transparency is good, have luster; It has good air tightness and fragrance retention; Moderate moisture resistance, moisture permeability decreases at low temperature. The mechanical properties of PET film are excellent, its strength and toughness are the best of all thermoplastics, the tensile strength and impact strength are much higher than ordinary films; and good stiffness, stable size, Suitable for printing, paper bag, waterproof material and other secondary processing.
PET film also has excellent heat and cold resistance, good chemical resistance and oil resistance. But it is not resistant to strong alkali,Easy to carry static electricity, there is no proper way to prevent static electricity, therefore, attention should be paid to the packaging of powdery articles.
