[Scope of utility model registration request]

The bottom end of the heat-adhesive flexible synthetic resin bag 1 is folded to form a square bottom part 3, and a square bottom-shaped cardboard bottom plate 4 such as cardboard is inserted inside the square bottom part 3. The bottom surface of the cardboard base plate 4 is brought into contact with the back surface of the cardboard base plate 4 from the outside of the square base part 3 by applying heat and pressure in an appropriate linear form to cause the molten resin to permeate into the inside of the paper surface of the cardboard base plate 4 . A synthetic resin bag with a bottom plate is provided with a square bottom plate part B by thermally bonding the square bottom part 3 to a cardboard bottom plate 4 by heat bonding 5.
