① Has good mechanical properties, impact strength is 3 to 5 times that of other films, and good folding resistance.

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

③ Has excellent high and low temperature resistance, can be used in the temperature range of 120℃ for a long time, short-term use can withstand high temperature of 150℃, can withstand low temperature of -70℃, and high and low temperature have little effect on its mechanical properties.

④ Low permeability of gas and water vapor, and excellent resistance to gas, water, oil and odor.

High transparency, can block ultraviolet light, good luster.

⑥ Non-toxic, tasteless, good safety.
