PROBLEM TO BE SOLVED: To provide a paper cup which does not leak due to pinholes and omission of seals, and does not break the paper layer of the container when the heat-sealed lid member is peeled, and which can be easily opened without impairing the sealing strength. SOLUTION: In a paper cup P comprising a cylindrical cup body member W and a bottom member that seals the bottom of the cylindrical cup body member W, the innermost layer 6a of the body member W has a density of 0.90. ~0.93g / cm, low density polyethylene resin layer is 3, the bottom member F, characterized in that it consists of a linear low-density polyethylene resin layer polymerized using a metallocene single-site catalyst [ Selection diagram] FIG. |
