PROBLEM TO BE SOLVED: To provide an inexpensive biaxially-stretched polypropylene resin film good in oxygen gas 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 amorphous silica particles (B), laminated on its one surface through an adhesive layer. The oxygen permeability of the resin film under the atmosphere of a relative humidity of 85% is set to 1,000 ml/m<SP>2</SP>/day/MPa or less. COPYRIGHT: (C)2004,JPO
