PROBLEM TO BE SOLVED: To provide a gas barrier film having hot water resistance that does not cause interlayer peeling and deterioration in barrier properties even when subjected to hot water treatment under more severe conditions and to provide a medical infusion packaging material, a food packaging material, a packaging material for an electronic material and a sheet for solar battery each using the film.SOLUTION: The gas barrier film having hot water resistance is a gas barrier film produced by laminating at least a first polymer resin, a gas barrier substance and a second polymer resin in this order on a surface-treated surface of a substrate film subjected to surface treatment. The first polymer resin is obtained by mixing an organic/inorganic hybrid resin and an organic metal compound and the second polymer resin contains a water-soluble polymer produced by mixing two kinds of modified PVA obtained by partially substituting a hydroxy group of PVA, a metal alkoxide and a coupling agent. The medical infusion packaging material, a food packaging material, a packaging material for an electronic material and a sheet for solar battery use the film. |
