PVC protective filmPET protective film is a kind of film bag with comprehensive performance. It has good light transmittance and gloss; excellent sealing and fresh-keeping; moderate water resistance, and the melt flow rate decreases at ultra-low temperature. The mechanical performance of PET protective film is good, and its tensile strength and impact resistance and compressive strength are much higher than that of ordinary plastic films; and it has good hearing ability and stable specifications, which is suitable for secondary production and processing such as packaging and printing, paper bags, etc. PET protective film also has good high temperature resistance, cold resistance and excellent chemical resistance and abrasion resistance.
PET protective film is a common maintenance sticker on the market at this stage, and the organic chemical name is polyester film. The characteristics of PET protective film are that the material is relatively hard and scratch-resistant. And long-term application will not yellow and oil like PVC material. However, the general PET protective film is all electrostatically adsorbed, which is very easy to foam and fall off, but even if it falls off, wash it in cold water and reuse it many times. The price of PET protective film is much more expensive than that of PVC. When many overseas brand mobile phones go to the original factory, they are equipped with PET maintenance stickers.
