Abstract:
1. An air-packing device inflatable by compressed air for protecting a product therein, comprising: first and second thermoplastic films superposed with each other where predetermined portions of the first and second thermoplastic films are bonded, thereby creating a plurality of air containers; a plurality of heat-seal lands each sealing the first and second thermoplastic films in a small area of the air container in a manner to allow air flow between the air cells, thereby creating a plurality of series connected air cells for each air container; a plurality of check valves for corresponding air containers established between the first and second thermoplastic films for allowing the compressed air to flow in a forward direction; and an air input commonly connected to the plurality of check valves to supply the compressed air to the air cells through the check valves; wherein the air-packing device includes a body portion extending in a longitudinal direction and two flap portions at each end, the flap portions overlapping with the body portion, each flap portion including a first section extending from the body portion and a second section extending from the first section, wherein each flap portion including side edges extending in the longitudinal direction, the side edges of the first section being bonded to the body portion and the side edges of the second section being separate from the body portion.
