Laminating film and laminate
Abstract:
To provide a laminate film having better shaping processability than conventional laminate films by disposing between the first resin layer 1 and the adhesive layer 3 the second resin layer 2 which has a Vicat softening point lower than that of the first resin layer, has a melting point lower than that of the first resin layer by 2° C. or more, is at least 0.5 times thicker than the first resin layer, and contains as the main component a propylene-&agr;-olefin copolymer. In addition, it becomes possible to provide the laminated structure 5 having the laminate film provided with the second resin layer 2 on the substrate 4. Hence, the present invention has great industrial significance.
