ABSTRACT:
A paper container for a liquid including a base material including: a paper layer, a polyolefin type resin layer disposed on one side of the paper layer, for providing an outer surface, and a saturated polyester resin layer disposed on the other side of the paper layer by the medium of a polyolefin type resin layer, for providing an inner surface; the paper container being formed from the base material so that the polyolefin type resin layer for providing the outer surface provides an outer peripheral surface of the container, wherein the saturated polyester resin layer for providing the inner surface comprises an amorphous or low crystallinity saturated polyester resin having a glass transition point of not lower than 40.degree. C., and a portion of the base material to be disposed on the inner side of the paper container with respect to the paper layer has a water vapor permeability of not higher than 25 g/m.sup.2 .multidot.24 hr.multidot.1 atm. When such a paper container is used, the content contained therein may retain its aroma component in a good state, and the water in the content does not penetrate into the paper container.
