Zusammenfassung:PROBLEM TO BE SOLVED: To provide a sealer which can degas simultaneously at the time of heat-sealing. SOLUTION: Two heater portions 1 for interposing an opening end of a packaging bag to be heat-sealed from outside to heat-contact-bond are oppositely placed so that they can come closer to or farther away from each other, and a flexible pressing plate 2 hang-supported with an upper end fixed is provided below each heater portion 1. As a result, heat-sealing is done after the pressing plate 2 has excluded air in an upper part of the packaging bag, so that a degassing process and a sealing process can be performed simultaneously, thereby reducing entire process cycle time and further simplifying facilities.
