Abstract

[Constitution] A heat shrinkable polyethylene laminate film having an excellent applicability to packaging machines is obtained by forming an intermediate layer composed of a composition comprising as a main component a linear low density polyethylene (A) having a density of 0.910 to 0.930 g/cm3, a melt index of 0.1 to 0.8 g/10 minutes, a total heat of fusion of at least 135 mJ/mg and an endothermic area in the range of not lower than the melting point of at least 12 % based on the total endothermic area, and forming innermost and outermost layers composed of a composition comprising as a main component a linear low density polyethylene (B) having a density of 0.910 to 0.930 g/cm3, a melt index of 0.8 to 5.0 g/10 minutes, a total heat of fusion of 135 to 160 mJ/mg and an endothermic area in the range of not lower than the melting point of at least 12 % based on the total endothermic area.
