Abstract:
An air bag packaging arrangement adapted to have a self-adhesive checking valve includes an air bag and an air valve which is the self-adhesive checking valve. The air bag includes first and second cell overlapped layers to form an air chamber and a valve opening. The air valve includes first and second sealing films overlapped between the first and second cell layers, and a check sealing film overlapped between proximal portions of the first and second sealing films to define an air inflating channel between the first sealing film and the check sealing film, and a backflow prevention channel between the check sealing film and the second sealing film. In case of air leakage, the air is guided to flow to the backflow prevention channel for creating a supplemental air pressure to further seal and close the air inflating channel, so as to make up a deficient sealing effect of the first and second sealing films.
