ABSTRACT:
Provided is a gas barrier film in which in coating or laminating a single layer film or a multiplayer film comprising at least one (a) thermoplastic resin layer on which an inorganic compound is vapor deposited or (b) layer comprising metal foil, wherein 40% by weight or more of a skeletal structure represented by the following Formula (1) is contained in an epoxy resin-cured product formed from an epoxy resin composition comprising an epoxy resin and an epoxy resin curing agent as principal components. The above gas barrier film has a toughness and a high gas barrier property brought about by the above epoxy resin composition used for adhering or coating on various film materials in addition to a suitable adhesive performance to various film materials, so that it is a gas barrier film which does not cause a marked reduction in a gas barrier property brought about by treatment such as bending in mold-processing of the film and which is excellent in a flexibility
