<p>The present invention relates to a gas-barrier laminate for hydrothermal treatment which comprises a base plastic film, a coating layer formed on at least one surface of the base plastic film, an inorganic thin film formed on a surface of the coating layer which is made of a metal compound, and a heat-sealable plastic film laminated on the inorganic thin film or the base plastic film, wherein the inorganic thin film before laminating the heat-sealable plastic film thereon has a rubbing strength of not less than 20 times as measured under a load of 70 g, and the coating layer has a hardness of 0.15 to 0.40 GPa. The laminate of the present invention is excellent in interlaminar bonding property, hardly undergoes breakage of the inorganic thin film owing to the hydrothermal treatment, and can maintain an excellent gas-barrier property even after subjected to the hydrothermal treatment.</p> |
