摘要： The aim is to provide a paper container for liquid that has a strength to prevent breakage or leakage due to a shock in a long-distance transportation and also has no problems in opening the container when used.This invention is a paper container for liquid which comprises a laminated body which comprises a paper as base material thereof and a heat-sealant layer which is placed inner side of the container than the paper and which comprises a reinforcement layer and a liquid-contacting layer which is the side of contacting the liquid, wherein the reinforcement layer is a layer made of linear low-density polyethylene and the liquid-contacting layer is a layer made of low-density polyethylene and thickness ratio of the reinforcement layer and the liquid-contacting layer (thickness of reinforcement layer 5/thickness of liquid-contacting layer 6) that form the heat-sealant layer is in the range of 0.2-5. Moreover, it is characterized in that the density of the linear low-density polyethylene is in a range of 0.900-0.945 g/cm3. Furthermore, it is characterized in that the linear low-density polyethylene and the low-density polyethylene are additive-free resins to which no additives have been added.
