PROBLEM TO BE SOLVED: To provide a gas barrier laminated film excellent in gas barrier properties with respect to oxygen and steam, having flexibility, humidity resistance and heat resistance, eliminating the lowering of the gas barrier properties caused by printing and lamination and easy to manufacture. SOLUTION: The gas barrier laminated film is constituted by laminating a coating layer, which is composed of methylolmelamine of which the methylol group is partially or wholly alkyl-etherified and a polyvinyl alcohol polymer and characterized in that the weight ratio of methylolmelamine/polyvinyl alcohol polymer is 25/75-90/10, on a base material comprising a high-molecular resin composition.
