ABSTRACT:
An air-packing device has an improved shock absorbing capability to protect a product in a container box. The air-packing device is configured by first and second plastic films which are bonded at predetermined portions thereby creating a plurality of air containers, each of the air containers having a plurality of series connected air cells; a plurality of check valves established at inputs of the corresponding air containers for allowing compressed air to flow in a forward direction; an air input commonly connected to the plurality of check valves; and heat-seal flanges formed on side edges of the air-packing device. Through a post heat-seal treatment, predetermined points on the air containers and the heat-seal flanges are bonded, thereby creating a container portion having an opening for packing a product therein and a cushion portion for supporting the container portion when the air-packing device is inflated by the compressed air.
