Heat shrinkable polyethylene laminate film

A biaxially stretched heat shrinkable polyethylene laminate film comprising an intermediate layer, an innermost layer on one side of the intermediate layer and an outermost layer on the other side of the intermediate layer, said intermediate layer being made of a composition comprising (A) a linear low density polyethylene having a density of 0.910 to 0.930 g/cm.sup.3 and a melt index of 0.1 to 0.8 g/10 minutes and showing a fusion curve wherein the total heat of fusion is at least 135 mJ/mg, and the endothermic area in the range of not lower than the melting temperature is at least 12% of the total endothermic area, and said innermost and outermost layers made of a composition comprising (B) a linear low density polyethylene having a density of 0.910 to 0.930 g/cm.sup.3 and a melt index of 0.8 to 5.0 g/10 minutes and showing a fusion curve wherein the total heat of fusion is from 135 to 160 mJ/mg and the endothermic area in the range of not lower than the melting temperature is at least 12% of the total endothermic area, said fusion curve being measured by a differential scanning calorimeter under conditions that the temperature is kept at 190.degree. C. for 30 minutes, dropped down to 20.degree. C. at a temperature dropping rate of 10.degree. C./minute and then raised at a temperature rising rate of 10.degree. C./minute, and the thickness of said intermediate layer being at least 60% of the thickness of all layers.
