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 paper container for a liquid is structured of a laminate 101a in which a thermoplastic resin layer 1, a paper base material 2, a barrier layer 4 and a sealant layer 6 are sequentially laminated from an outer layer side to an inner layer side; and includes a cylindrical trunk, a top portion closing the upper end of the trunk, and a bottom portion closing the lower end of the trunk. The paper base material or a region from the thermoplastic resin layer to the paper base material is subjected to scratch processing A, a region from the barrier layer to the sealant layer is subjected to scratch processing B, and the scratch processing B is provided at approximately the same position as a position of the laminate on which the scratch processing A is provided.SELECTED DRAWING: Figure 1 |
