Detail
Air-valve film is used as the seal of air cushion bag. It is made of two film sheets sticking together and seals the air by itself after being inflated, which could effectively stop air going back, so called “air-valve film”. Based on physical theory, one-time inflation fills all the air cushion bag with has isolated air columns that won’t be effected if either of them leaks. In this way, the whole air cushion function would be maintained.
