特徴とする紙袋。 one side of a laminated sheet consisting of an outer paper sheet and a thermally adhesive film sheet bonded to at least the inner surface of the paper sheet is folded back to the outside, which is the paper sheet side, to form a folded part; Then, with the film sheet inside, the other side of the laminated sheet is joined to the outside of one side to form a watertight cylindrical body, and the inner film sheets facing each other at the bottom of the cylindrical body are bonded to the outside of one side. In a paper bag formed by thermal bonding, the paper sheet in the folded part of the one side is removed along the longitudinal direction to form only the film sheet, and the double film sheet in the folded part is attached to the cylindrical body. A paper bag characterized in that the film sheet on the inside of the bottom is integrally thermally bonded.
