<p>PROBLEM TO BE SOLVED: To improve the barrier properties of a laminated material and prevent film cracks or interlayer peeling from being generated in the laminated material by laminating at least a base film, an aluminum oxide film formed on one of the faces of the base film, a medium film containing moisture and a heat-seal resin layer sequentially in that order. SOLUTION: The laminated material 1 is structured of for example, an aluminum oxide film 3 formed on one of the faces of a base film, a medium film 4 containing moisture and a heat-seal resin layer 5 laminated sequentially. The manufacturing method is to form an aluminum oxide deposited film with about 200-400Åfilm thickness, for example, first on one of the faces of the base film 2, for example, using a physical gas phase growth method or the like. Next the heat-seal resin layer 5 is laminated on the deposited film face through, for example, one layer or two layers or more of an anchor coating agent layer formed of an aqueous anchor coating agent, a laminate adhesive layer of an aqueous laminate adhesive, an ink layer of an aqueous ink composition or a resin layer of an aqueous resin composition.</p> |
