摘要：PROBLEM TO BE SOLVED: To provide a paper container made of a laminated material, which is excellent in low temperature sealability at the time of manufacture of the paper container, sufficiently copes even with a part having difference in level at the time of heat sealing, causes no pinhole, and is especially good in the adhesiveness of a barrier layer and a thermoplastic resin layer. SOLUTION: The paper container is constituted using the laminated material obtained by successively laminating at least: the outermost layer; a paper base material layer; a thermoplastic resin layer constituted by providing a vapor deposition film of an inorganic oxide and a primer coating film on one side of the base material layer; an intermediate polyethylene layer; and the innermost layer formed by laminating the polyolefin resin on the side of the intermediate polyethylene layer and an ethylene/α-olefin copolymer polymerized using a metallocene catalyst on a content contact side by coextrusion.
