Abstract: An air-packing device has an improved shock absorbing capability to protect a product in a container box. The air-packing device is comprised of first and second thermoplastic films where predetermined portions 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 thereby creating a plurality of series connected air cells for each air container, a plurality of check valves for corresponding air containers for allowing the compressed air to flow in a forward direction. The plurality of heat-seal lands at predetermined sides of the air-packing device create triangled areas of the air cells, and the air-packing device is folded at the heat-seal lands, thereby creating an inner space for packing a product therein.

The air-packing device is folded after the product is inserted in the pocket and installed in a container box.

Abstract: A bubble wrapping sheet has a simple structure and can easily inflate all of the air bubbles to wrap a product to be protected. The air bubbles can be constructed by tube partition seals that create air tubes and by bubble partition seals that divide the air tubes into a plurality of series connected air bubbles. The shape and size of the tube partition seals and bubble partition seals can be modified to change the shape of air bubbles and the density of the air bubbles on the bubble wrapping sheet. A check valve for the bubble wrapping sheet is provided to each air tube. The check valve may be configured by an air flow maze portion having a zig-zag air passage and a common air duct portion which provides the air to the air flow maze portion of a current air tube as well as to the air flow maze portion of a next air tube.
