Abstract
An object of the present invention is to provide a barrier film whose gas barrier properties hardly deteriorate even after a retort treatment and after a Gelboflex test. The barrier film of the present invention includes a barrier coat layer, an inorganic oxide deposition layer, and a substrate layer, in this order, wherein the barrier coat layer has a hardness of 1.10 GPa or more and 1.55 GPa or less, and a plastic deformation rate of 21.0% or more.
