Abstract: The influence of the type and amount of inorganic nanocomposite additive on the properties of polyethylene were studied.

The inorganic nanocomposite additive A was selected as the polyethylene casting film heat sealing layer additive, with the addition

amount of 4000×10-6 . PE-LF274PC was prepared with Ti catalyst. The melt mass flow rate was 3.4~4.0 g/(10 min), and the density

was 0.927~0.930 g / cm3 . The haze of the cast film is less than 6% and the gloss is more than 86. The application showed that

PE-LF274PC was suitable for the production of casting film heat seal layer and met the consumers' demand.
