PROBLEM TO BE SOLVED: To provide a paper container for a liquid which can be easily disassembled, has stable sealability, and is hardly broken.SOLUTION: A laminate 101a for a liquid paper container is structured of a laminate in which a thermoplastic resin layer 1, a paper base material 2, a barrier film layer 4 and a sealant layer 6 are sequentially laminated from an outer layer side to an inner layer side. The barrier film layer includes a barrier layer and a base material film layer, and is subjected to scratch processing 7 with such a depth as to penetrate through the paper base material and penetrate through the base material film layer of the barrier film layer.SELECTED DRAWING: Figure 1 |
