Abstract
The invention relates to an air packing device and a production method thereof. Two layers of thermoplastic films are thermally sealed to form a space in which air can be stored. The air packing device comprises a plurality of independent sealed air chambers and a main passage. The main passage is provided with an air inlet. Each sealed air chamber is communicated with the main passage through a one-way valve which consists of two layers of films. Two or more than two one-way valves are installed in partial air chambers or all air chambers. By increasing buffers at main parts and decreasing the magnitude of air columns at many parts which are not required to be protected, the volume can be effectively reduced and the transportation cost is decreased. By adopting a method of directly forming the air packing device on the site of use, the transportation space and the transportation cost can be greatly reduced and therefore the problem that the long-distance transportation cost of packing materials is too high is solved.
