<p>PROBLEM TO BE SOLVED: To provide a packaging material constituted by laminating a base film, an adhesive layer, a sealant layer in the order named, which suppresses deterioration of laminate strength of the individual layers even when packaging a content containing a volatile ingredient and a highly permeable ingredient.SOLUTION: An adhesive layer 3 is formed of a bifunctional or polyfunctional isocyanate compound. A base film is formed of an outer film 1 and an intermediate film 2. The intermediate film 2 is formed of a film obtained by laminating a primer layer 22, an inorganic vapor-deposited layer 23, and a gas barrier coat layer 24 in the order named on an intermediate film base 21.</p> |
