Patent ID: 11878494

Abstract:
The objective of the present invention is to provide a gas barrier polyamide film excellent in water resistance adhesiveness (water resistant laminate strength), impact resistance and pinhole resistance. The gas barrier polyamide film is characterized in comprising a stretched polyamide film, wherein the stretched polyamide film comprises A Layer: a base layer and B Layer: an easily adhesive layer on at least one surface of the A Layer, C Layer: an inorganic thin film layer is laminated on the surface of the B Layer in the stretched polyamide film, the A Layer comprises 65 mass % or more of Polyamide 6, the B Layer comprises 60 to 100 mass % of a Polyamide 6 copolymer and 0 to 40 mass % of Polyamide 6, and a ratio of a copolymer component in the Polyamide 6 copolymer is 3 to 35 mass %.
