PROBLEM TO BE SOLVED: To provide an oxygen gas barrier film generating no hydrogen chloride gas at combustion and enhanced in oxygen barrier properties and sealant adhesiveness under a high humidity condition. SOLUTION: The biaxially stretched polypropylene resin film has a polyvinyl alcohol resin layer, which comprises a mixture of a polyvinyl alcohol resin (A) with a polymerization degree of 200-2,600 and a saponification value of 90.0-99.7 mol % and a polyacryl resin (B), laminated on its one surface through an adhesive layer. The oxygen permeability of the resin film under an atmosphere of a relative humidity of 85% is set to 300 ml/m<SP>2</SP>day MPa or less. COPYRIGHT: (C)2004,JPO
