Oxygen permeability, which is formed by providing a base film with a thin film of a metal compound selected from the group consisting of oxides, carbides, nitrides, or mixtures thereof, followed by heat treatment, and then installing a plastic film on the thin film of the metal compound, has an oxygen permeability of 2 cc. In the gas barrier layered product having a temperature of / m 2 / day / atm or less, when the hot water treatment is performed at 120 ° C. for 30 minutes, the oxygen permeability change (after treatment / before treatment) of the laminate before and after the hot water treatment is 5. The gas barrier layered product characterized by the above-mentioned. |
