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.

A multi-purpose air-packing method and system enables to pack a product having an irregular shape easily at low cost. The air-packing method includes the steps of placing a product to be protected in a container box; applying a first air-packing device having a plurality of air containers to side surfaces of the product in a manner to surround the product in the container box where each of the air containers has a check valve to maintain compressed air therein independently from one another; and inflating the air-packing device by supplying compressed air to securely hold the product within the container box. Two or more consecutive air containers at one end of the first air-packing device have a cross sectional size smaller than that of other air containers.

Multi-purpose air-packing method and system

A check valve for use in an air-packing device has a simple structure and promotes to easily inflate all of the air cells of the air-packing device with a relatively lower pressure. The check valves can be easily attached to any locations of the air-packing device. The check valves are formed when a check valve film is attached to one of the first and second thermoplastic films. Peeling agents of predetermined pattern are applied on the check valve film which prevents heat-sealing between the first and second thermoplastic films for air tightly separating two adjacent air containers. The check valve is 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 container as well as to the air flow maze portion of a next air container.

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 only in a forward direction; and an air input commonly connected to the plurality of check valves. Through a post heat-seal treatments, predetermined edge portions are bonded, thereby creating an inner space for packing a product therein and an opening for loading the product therethrough.
