Title: AIR-FILLED PACKAGING BAG HAVING NO MEMBRANE VALVE, MANUFACTURING METHOD THEREFOR AND INFLATING DEVICE
Abstract:
An air-filled packaging bag having no membrane valve, a manufacturing method therefor and an inflating device, said manufacturing method comprising the following steps: pumping air into an air storage unit (13) of an uninflated membrane-valveless air-filled packaging bag via an inflation unit (15); heat-sealing the inflated air storage unit (13), so as to form a sealing seam (105) at the air inlet thereof and thus sealing the air inside same; performing the same inflation and heat-sealing operations successively with respect to all the air storage units of the valveless air-filled packaging bag so as to complete inflation of same and thereby obtain the inflated valveless air-filled packaging bag. The valveless air-filled packaging bag when inflated is a 3-dimensional packaging bag and may be used for the packaging of at least one object.
