Abstract: A method for producing a paper container and a paper container for liquid. A method for producing a paper container for liquid according to an aspect includes a bonding step of bonding a first surface of a substrate and a vapor deposition surface of a barrier laminate film layer via a first adhesive resin layer without applying a corona treatment to the vapor deposition surface of the barrier laminate film layer, a lamination step of laminating at least a second adhesive resin layer on a surface of the barrier laminate film layer on a side opposite to the vapor deposition surface, and a forming step of forming a laminate into a box shape after the bonding step and the lamination step, the laminate including at least the substrate, the first adhesive resin layer, the barrier laminate film layer, and the second adhesive resin layer.
