<p>An easily openable laminated film comprising a hot-melt layer composed of an olefin polymer composition (E), an intermediate layer composed of an ethylene polymer composition (F), and a laminate layer composed of an ethylene polymer (B-4). The olefin polymer composition (E) comprises a propylene polymer (A-1), an ethylene polymer (B-1), an ethylene-α-olefin random copolymer (C-1), and a adhesion-imparting resin (D-1). The ethylene polymer composition (F) comprises an ethylene polymer (B-2) and a high-pressure-process low-density polyethylene (B-3). The easily openable laminated film has sealing strength capable of resisting pressure from outside (external pressure) and pressure from inside (internal pressure), even when the seal; i.e., the casing, is at a temperature above room temperature, while maintaining excellent sealing properties and easy-opening properties.</p> |
