Patent ID: 7651779

Claim:
A heat-sealable laminated film obtained by laminating a substrate layer on one surface of a heat-sealable film comprising a resin composition having an easy-openable property directly or through a laminated layer, wherein the resin composition comprises an ethylene polymer composition (D) comprising 5 to 65 wt % of a propylene polymer (A), 1 to 35 wt % of an ethylene/α-olefin random copolymer (B) having a density of less than 895 kg/m 3 and 10 to 85 wt % of an ethylene polymer (C) selected from the group consisting of (a) a linear low density polyethylene having a density of 895 to 925 kg/m 3 prepared by using a catalyst containing a metallocene compound of a transition metal and (b) a high density polyethylene having a density of greater than 940 kg/m 3 and up to 970 kg/m 3 (in a total amount of 100 wt %).
