PROBLEM TO BE SOLVED: To provide a polyamide film which has oxygen barrier properties, has physical properties (transparency, deformation recoverability, etc.) to enhance the grade of a package even when used for various packaging applications such as a pillow shrink packaging, and is further able to be thinned while securing the oxygen barrier properties.SOLUTION: A polyamide film is obtained by biaxially stretching a polyamide resin that includes a diamine unit containing 70 mol% or more of a meta-xylylene diamine unit, and a dicarboxylic acid unit containing 70 mol% or more of a 4-20C linear aliphatic dicarboxylic acid unit, wherein the ratio of a soft segment is 30% or less. |
