[Abstract] The present invention provides an adhesive for a laminate product containing as an essential component an epoxy resin composition containing an epoxy resin and an epoxy resin curing agent, said epoxy resin composition being formed Epoxy resin cured product containing the skeletal structure represented by the formula (1) in an amount of at least 40% by weight: Since the adhesive of the present invention has not only proper adhesion to various film materials but also has high gas content The barrier property is that only the single layer formed by it can be combined to achieve excellent gas barrier property and excellent adhesiveness, so that it is possible to produce high gas for packaging materials without forming a separate gas barrier layer therein. Barrier laminating film.
