POLYETHYLENE CROSSLINKED SHRINK FILM

摘要

PROBLEM TO BE SOLVED: To provide a polyethylene crosslinked heat shrink film which satisfies high shrink boil package finish requirements required when packaging high-grade products such as cosmetic or chemical or the like and moreover does not impair productivity.SOLUTION: The polyethylene crosslinked shrink film is provided that comprises a core layer and a double surface layer. The core layer is obtained by using resin composed of: 5 to 15 wt.% of vinyl acetate content; 35 to 70 pts.wt. of ethylene-vinyl acetate copolymer with an MI (Melt Index) of 0.3 to 3.0 g/10 min.; 25 to 65 pts.wt. of a polyethylene elastomer with a density of 0.865 to 0.885 g/cmand an MI of 0.5 to 4.0 g/10 min. ; and 0 to 40 pts.wt. of very low density polyethylene with a density of 0.895 to 0.910 g/cmand an MI of 0.5 to 4.0 g/10 min. The double surface layer is obtained by using resin composed of: 80 to 95 pts.wt. of linear low density polyethylene with a density of 0.915 to 0.930 g/cmand an MI of 1.0 to 3.0 g/10 min.; and 5 to 20 pts.wt. of polyethylene elastomer with a density of 0.865 to 0.885 g/cmand an MI of 0.5 to 4.0 g/10 min. The polyethylene crosslinked shrink film is obtained by performing cross linking with electron beam irradiation and stretched.SELECTED DRAWING: None
