Abstract

Provided is a gas-barrier polyamide film that has excellent bending pinhole resistance and friction pinhole resistance at the same time, that has excellent gas barrier properties, and that is suitable for use for packaging materials. In addition, the environmental load is reduced by using a plant-derived resin as a raw material. A gas-harrier polyamide film comprising an inorganic thin film layer on at least one surface of a biaxially stretched polyamide film containing 99 to 70% by mass of a polyamide 6 resin and 1 to 30% by mass of a polyamide resin in which at least a part of raw material is derived from biomass.
