Plastic Packaging Film Factory Direct Sale

PET film is a kind of packaging film with comprehensive performance. It has good transparency and luster; It has good air tightness and fragrance retention; The moisture resistance is medium, and the moisture permeability decreases at low temperature. The mechanical properties of PET film are excellent, and its strength and toughness are the best among all thermoplastics. The tensile strength and impact strength are much higher than those of ordinary films; It has good stiffness and stable size, and is suitable for secondary processing such as printing and paper bags. PET film also has excellent heat resistance, cold resistance, chemical resistance and oil resistance. But it is not resistant to strong alkali; It is easy to carry static electricity, and there is no proper anti-static method. Therefore, attention should be paid when packaging powdery goods.
