▎ 摘　　要

NOVELTY - Packaging film comprises a first adhesive layer formed on the sealant layer (10), a core layer (20) formed on the first adhesive layer, a second adhesive layer formed on the core layer, and a surface layer (30) formed on the second adhesive layer. At least one of the sealant layer, first adhesive layer (401), second adhesive layer, and surface layer contains graphene. The graphene increases the durability of the entire retort food packaging film, and reduces gas permeability and moisture permeability. The core layer includes an aluminum foil or an aluminum deposition layer. The content of the graphene is 0.005-3 pts. wt. based on 100 pts. wt. each layer excluding the core layer. USE - The film is useful for packaging retort food and medicinal material. ADVANTAGE - The film has good moisture, temperature, oxygen, or light barrier properties, good ductility and impact resistance, and good chemical resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing a film for packaging retort food comprising forming a sealant layer, a core layer, and a surface layer, and laminating the sealant layer, the core layer, and the surface layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the packaging film. Sealant layer (10) Core layer (20) Surface layer (30) Adhesive layer (40) First adhesive layer (401)
