▎ 摘　　要

NOVELTY - Laminated film comprises a polypropylene base resin layer, a graphene layer arranged on top surface of the polypropylene base resin layer, an adhesive layer and a composite composition layer laminated on top surface of the graphene layer using the adhesive layer. The composite composition layer comprises 5-40 pts. wt. norbornene cyclic polyolefin, 0.5-20 pts. wt. polyolefin rubber or polyolefin elastomer and 1-20 pts. wt. inorganic nanoparticles based on 100 pts. wt. polypropylene resin. USE - The film is useful for retort food packaging (claimed). ADVANTAGE - The film has excellent heat resistance, transparency, gas barrier property and moisture barrier property.
