Laminated films

摘要

A laminated film has layer(s) A and layer(s) B1, obtained by laminating at least one layer A and at least one layer B1. The layer A comprises a resin composition comprising (a) 20-100% by weight of an amorphous polyolefin containing at least one component, in an amount of at least 50% by weight in said amorphous polyolefin, selected from the group consisting of propylene and butene-1 and (b) 80-0% by weight of a crystalline polypropylene, (B) the layer B1 comprises a crystalline polypropylene. At least one of the two outermost layer is the layer B1. The laminated films can be used in various applications by themselves, but may be laminated with a polyester film, a nylon film, a stretched polypropylene film or the like to improve the mechanical strengths, gas-barrier property, printability, etc.
