<p>PROBLEM TO BE SOLVED: To provide a packaging material, excellent in transparency, having high gas barrier property as well as high adhesive property, not being deteriorated in the physical property even after boil sterilization or retort sterilization, having high resistance to boiling as well as resistance to retort without generating any separating phenomenon or the like and high in the practical use of the same. SOLUTION: A strongly adhering gas barrier transparent laminate is formed by a method wherein a transparent primer layer 2, consisting of a composite of an acrylic polyol, a polyester polyol, an isocyanate compound and a silane coupling agent, and a deposit thin film layer 3, having the thickness of 5-300 nm and constituted of an inorganic oxide, are laminated sequentially on at least one side of a substrate 1 made of a transparent plastic material.</p> |
