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 a plurality of edge air-packing blocks. Each edge air-packing device includes a wall portion that surrounds and supports a pocket portion that holds an edge of the product to be protected such that the pocket portion does not contact the ground when shocks are applied to the air-packing device. Each of the enclosure portion and the pocket portion is configured by first and second thermoplastic films which are bonded at predetermined portions thereby creating a plurality of air containers. Each of the air containers has a check valve for allowing the compressed air to flow only in a forward direction.
