PROBLEM TO BE SOLVED: To provide a liquid paper container which can use a metal detector for foreign matter detection, has recycling property and has gas barrier property equivalent to that of an aluminum foil.SOLUTION: A liquid paper container with a square cylindrical shape comprises a blank of a laminated board in which a paper board is uses as a base material layer, and a thermoplastic resin layer/the base material layer/an adhesive layer/an intermediate layer/a sealant layer are laminated in the order. The liquid paper container with a square cylindrical shape is formed by folding the blank at folding lines, with the sealant layer as a back surface and sealing the blank, wherein the intermediate layer is a laminated film prepared by laminating at least two sheets of vapor deposition films in each of which inorganic oxide is vapor-deposited. |
