Abstract
In manufacturing a resin bag, a first resin sheet is disposed in a cavity of a mold, and a heat-resisting sheet smaller than the first resin sheet is overlaid on the first resin sheet to expose a periphery of the first resin sheet along the outer periphery of the heat-resisting sheet. Then, a molten resin is injected into the cavity in a state where the mold is opened, and the mold is closed while pressing and expanding the injected resin in a molten state. Thus, the injected resin covers the heat-resisting sheet and the exposed periphery of the first resin sheet. The second resin sheet is molded, and the periphery of the second resin sheet is bonded with the periphery of the first resin sheet at the same time.
