To provide a resin composition that has excellent gas barrier properties, especially oxygen barrier properties under high humidity conditions.SOLUTION: A resin composition contains a hydrophilic resin and a metallic compound. When the resin composition is made into a film, a degree of oxygen permeation (cc 3 μm/m2 day atm) at 23°C and 80%RH satisfies the following formula (1): degree of oxygen permeation (cc 3 μm/m2 day atm)≤80.SELECTED DRAWING: None 【課題】高湿度下におけるガスバリア性、特に酸素バリア性に優れる樹脂組成物を提供することを目的とする。【解決手段】親水性樹脂、及び金属化合物を含む樹脂組成物であって、上記樹脂組成物をフィルムにした際の、２３℃、８０％ＲＨ環境下での酸素透過度（ｃｃ・３μｍ／ｍ2・ｄａｙ・ａｔｍ）が、下記式（１）を満たすことを特徴とする樹脂組成物。酸素透過度（ｃｃ・３μｍ／ｍ2・ｄａｙ・ａｔｍ）≦８０ ・・・（１）【選択図】なし
