Abstract
A method of manufacturing a resin bag whereby the peripheral edge of the bag such as a resin air baa is not bulky, the bonding strength is still sufficient, and the productivity is increased, is provided. A first resin sheet and a heat-resisting sheet are overlaid on each other and are disposed in a cavity of a mold . The diameter of the heat-resisting sheet is smaller than that of the first resin sheet so that a portion of the sheet is exposed outside the heat-resisting sheet . After injecting resin ′ into the cavity through a sprue bush end , the resin ′is pressed and expanded to mold a second resin sheet and bond the sheet to the sheet at the peripheries thereof.
