<p>PROBLEM TO BE SOLVED: To provide a paper container for a liquid, in which a laminate of the paper container is formed in such a manner that its outer face portion composed of paper as a main body can simply be separated from its inner face portion comprising a vapor deposition layer composed of metal or a metallic oxide an a plastic film layer, thereby easily making the container to waste or reusable as resources. SOLUTION: This paper container for a liquid is formed of a laminate in which a thermoplastic resin layer 1, a paper layer 2, an adhesive resin layer 3, a vapor deposition layer 4 composed of metal or a metallic oxide, a plastic film layer 5, and a thermoplastic resin layer 6 are laminated in order named from an outer face of the laminate, and in which the adhesive strength between the adhesive resin layer 3 and the vapor deposition layer 4 is made to be 50-200 g/15 mm in width. The laminate is designed so that the adhesive resin layer 3 and the vapor deposition layer 4 can be peeled and separated from each other at the interface of both the layers.</p> |
