PURPOSE: To improve heat shrinkability and prevent matter to be packed from fusing with the film concerned by a structure wherein surface layer consisting of mixture of high-pressure-processed polyethylene resin or specified ethylene- vinyl compound copolymer resin and propylene-ethylene copolymer resin is laminated on both sides of intermediate layer made of high-pressure-processed polyethylene resin or ethylene-vinyl acetate copolymer resin.

CONSTITUTION: Surface layer consisting of mixture of high-pressure-processed polyethylene resin or 70-85wt.% of ethylene-vinyl compound copolymer resin containing 20wt.% or less of vinyl compound and 30-15wt.% or propylene- ethylene copolymer resin is laminated on both sides of intermediate layer made of high-pressure-processed polyethylene resin or ethylene-vinyl acetate copolymer resin containing 20wt.% or less of vinyl acetate. As the ethylene-vinyl compound copolymer resin, ethylene-acrylic acid copolymer, ethylene-ethyl acrylate copolymer or the like is used including ethylene-vinyl acetate copolymer.
