<p>PROBLEM TO BE SOLVED: To provide a packing material having a laminated film bonded and laminated by blocking, having necessary physical strength, generating no curling and having recycle properties, reuse properties and stable blocking adhesive strength. SOLUTION: A packaging material is constituted of a laminated film of two miltilayered coextrusion inflation films each having a highα-olefinic resin layer based on a highα-olefinic resin containing 1 wt.% or more of a 4 or more Cα-olefin and a special ethylene copolymer resin layer based on a special ethylene copolymer resin containing 5-40 wt.% of one or more of vinyl acetate and acrylic acid. The special ethylene copolymer resin layers of two multilayered coextrusion inflation films are mutually bonded and laminated by blocking.</p> |
