POLYETHYLENIC MULTILAYERED STRETCHED FILM

摘要

PROBLEM TO BE SOLVED: To provide a polyethylenic multilayered stretched film good in stretching processability and low temperature heat sealability or heat resistance. SOLUTION: A specific amount of a straight chain extremely low density polyethylene resin having a specific density is added to a straight chain low density polyethylene resin of a surface layer and a specific amount of a straight chain high density polyethylene resin having specific density is added to a straight chain low density polyethylene resin of a core layer. Or, a specific amount of a straight chain high density polyethylene resin having a specific density is added to the straight chain low density polyethylene resin of the surface layer and a specific amount of a straight chain extremely low density polyethylene resin having a specific density is added to the straight chain low density polyethylene resin of the core layer.
