A storage method for storing a package containing content, under irradiation of light. At least a part of a package is formed by polyamide (A) which is obtained by polycondensation of a diamine component containing at least 70 mol% of meta-xylylenediamine, and a dicarboxylic component containing at least 70 mol% ofα,ω-straight-chain aliphatic dicarboxylic acid having 4 to 20 carbons. When the light is irradiated to the package comprising the polyamide (A), oxygen permeability is decreased, and deterioration of the content can be suppressed. |
