①It has excellent mechanical properties, the impact strength is 3~5 times that of other films, and the folding resistance is good.

② oil resistance, fat resistance, dilute acid, dilute alkali resistance, resistance to most solvents.

③It has excellent high and low temperature resistance, can be used for a long time in the temperature range of 120 °C, can withstand high temperature of 150 °C for short-term use, and can withstand low temperature of -70 °C, and has little impact on its mechanical function at high and low temperatures.

④The permeability of gas and water vapor is low, that is, it has excellent function of blocking gas, water, oil and peculiar smell.

⑤ High transparency, can block ultraviolet rays, and good gloss.

⑥ Non-toxic, odorless, clean and safe, can be directly used for food packaging.
