1. It has good mechanical properties and folding tolerance
2. It is resistant to oil, fat, dilute acid and alkali, most solvent.
3. It has excellent temperature tolerance. Long-term workable under 120°C ,
shortterm appliable under (150°Cor -70°C)slightly affection to its mechanical
properties under high or low temperature
4. It has low gas and vapor permeability, and good resistance to gas, water,
oil and odor.
5. It has high transparency and glossy, also can block ultraviolet ray.
6. It can be directly used in food packing since it is non-toxic, unscented with good sanitary security.
