Advantages of PET :
1. Has good mechanical properties, impact strength is 3 to 5 times that of other films, and good folding resistance.
2. Oil resistant, fat resistant, olefin resistant, dilute alkali, resistant to most solvents.
3. The heat resistance of pure PET is not high, and the heat distortion temperature is only about 85 °C, but it is greatly improved after the enhanced treatment. The mechanical properties of PET after glass fiber reinforced are similar to engineering plastics such as PC and PA. The heat distortion temperature can reach 225 °C. The heat aging resistance of PET is good, the embrittlement temperature is -70 °C, and it still has a certain temperature at -30 °C. Toughness; PET is not easy to burn, the flame is yellow, and the burning oil drops.
4. Low gas and water vapor permeability, excellent gas barrier, water, oil and odor properties.
5. High transparency, UV blocking, good gloss.
6. Non-toxic, odorless, good health and safety, can be directly used for food packaging.
