Development of Special Material for PE heat-sealing layer
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.
