| description | PROBLEM TO BE SOLVED: To provide an adhesive composition having a proper adhesive property suitable for a packaging material which is opened easily and can be sealed again and a laminated film in which the adhesive composition is made an intermediate layer and which especially improves the low temperature heat-sealability and easy openability of a heat-seal layer in the packaging material made of the laminated film. SOLUTION: The laminated film contains the adhesive composition comprising an olefinic block copolymer elastomer (A), an ethylene-vinyl acetate copolymer (B) with a vinyl acetate content of 25-80 wt.%, and a tackifier (C) as a basic component. A laminate layer made of a thermoplastic resin (D) and the heat-seal layer made of a thermoplastic polymer comprising a propylene random copolymer (E1) and a component (E2) selected from an ethylenic resin and a thermoplastic elastomer are laminated through the intermediate layer made of the composition.
