<p>PROBLEM TO BE SOLVED: To render an inner surface layer consisting principally of plastics disposable easily by being formed of a thermoplastic layer, a paper layer, an adhesive resin layer, a separation layer, an intermediate layer and a thermoplastic resin layer, and forming a paper container from a laminated body that is separably laminated at an interface of the separation layer. SOLUTION: A blank plate such as a gable top-type container is laminated with a polyethylene layer 1, a paper layer 2, an adhesive layer 3, a separation layer 4, a plastic film layer 5, a gas barrier layer 6, and a polyethylene layer 7 in turn from the outer surface, and the intermediate base material layer is formed of a plastic film layer 5 and gas barrier layer 6. In this instance, a separation of the laminated body at an interface of the separation layer 4 allows an outer layer consisting of the polyethylene layer 1, paper layer 2, and adhesive layer 3 to be separable from an inner surface consisting of the plastic film layer 5, gas barrier layer 6, and polyethylene layer 7. Consequently, the outer layer consisting mainly of paper is made easily recyclable and, at the same time, the inner layer consisting principally of plastics is made easily disposable.</p> |
