PROBLEM TO BE SOLVED: To provide a multilayered film having an oxygen gas barrier property which has an excellent oxygen gas barrier property, especially exerts the excellent oxygen gas barrier property even under a high humidity, and can be manufactured from an easily available material at low cost. SOLUTION: In this multilayered film, an oxygen gas barrier layer which comprises a mixture of a polyvinyl alcohol resin layer of 100 pts.wt. and a polyalkyleneglycol surfactant of 0.01-5 pts.wt. is formed at least on one side face of a base material film layer, an oxygen permeability under an atmosphere at 23 deg.C and relative humidity of 85% is 1000 mL/m<2> .day.MPa or less. |
