Industry information

PET protective film is currently the most common type of protective tape on the market, chemically known as polyester film. The PET protective film is characterized by a relatively hard texture and is relatively scratch resistant. And long-term use will not turn yellow like oil. However, the general PET protective film relies on electrostatic adsorption, which is relatively easy to foam and fall off, but can be reused even if it is washed off in clean water. The price of PET protective film is much more expensive than PVC. When many foreign well-known brand mobile phones are shipped from the factory, the PET protection stickers are randomly arranged. The PET material protection stickers are more exquisite in workmanship and packaging. There are special protection stickers for hot mobile phone models, which can be directly processed without cutting. Use, some of the well-known brands of mobile phone film on the market are also produced from PET materials.

PET protective film is a relatively comprehensive packaging film. It has good transparency and luster; it has good air tightness and aroma retention; it has moderate moisture resistance, and its moisture permeability decreases at low temperatures. PET protective film has excellent mechanical properties, its toughness is the best among all thermoplastics, tensile strength and impact strength are much higher than general film; and it has good strength and dimensional stability, suitable for printing, paper bags, etc. machining. The PET protective film also has excellent heat resistance, cold resistance, and good chemical resistance and oil resistance.
