▎ 摘　　要

NOVELTY - Electromagnetic shielding polypropylene composite film, comprises at least one film layer A formed from a polypropylene composition A and at least one film layer B formed from a polypropylene composition B. The polypropylene composition A comprises homopolypropylene a, propylene impact copolymer b and polyolefin elastomer c, and the polypropylene composition B comprises a resin component and an electromagnetic shielding filler. The resin component comprises a random polypropylene x and optionally a polyolefin elastomer y. USE - The electromagnetic shielding polypropylene composite film is useful in the field of packaging material, preferably electronic product packaging (claimed). ADVANTAGE - The film has good impact resistance, tensile performance and electromagnetic shielding performance, and good heat sealing strength at a relatively low heat sealing temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing electromagnetic shielding polypropylene composite film comprising extruding and casting the raw material composition to form each layer after optional granulation process to form the composite film, optionally, the method further comprising stretching the obtained composite film, preferably biaxial stretching.
