To provide a paper container which has a printed layer excellent in glossiness, and of which the bonding at the time of molding can easily be performed.
A container shape is formed by using a laminated sheet 11, and the problem of bondability is solved by making the front and the rear of the side seam 11c the same resin layer. In this case, the laminated sheet 11 is composed of a laminate of at least a drawn high-density polyethylene film layer 12 which is formed on the surface, a rear surface printed layer 13 which is printed on the rear surface of the drawn high-density polyethylene film layer 12, a stencil paper layer 14 which is bonded to the rear surface printed layer 13 of the drawn high-density polyethylene film layer 12, and a polyethylene film layer 17 which is formed on the rear surface of the stencil paper layer 14. Thus, the paper container which has the printed layer 13 excellent in glossiness and can be molded and bonded without inviting the increase of processes is provided.
