Abstract
A resin composition containing a hydrophilic resin and a metal compound, and satisfies the following expression (1) when being formed into a film:α1−β1≥1 (1)wherein α1 is an average metal atom concentration (%) in a portion of the film in a depth range of 0 to 9 nm from a film surface, and β1 is an average metal atom concentration (%) in a portion of the film in a depth range of 12 to 21 nm from the film surface. The resin composition is excellent in gas barrier property, particularly in oxygen barrier property, in a high humidity environment.
