气排包装袋是由个个相对独立的气柱相连接组成的气排，每个气柱都有独立的逆压阀，单独的气柱破裂不会导致其它的气柱漏气，处用气囊的缓冲原理使物品得到最安全的保护，可根据被包装物品的形状设计相应的形状，按被包装物品的形状气排可以任意折角，从而使物品包装达到最体积，可以循环使用。

Air-valve packing bag is composed of lots of independent valves to form a connectional air-valves, each valve has its own check valve. The breakage of one air-valve can not influence the working of others. Under the theory of air buffering, it can make the goods safely protected with different design shapes or dimensions requirements of the goods, which makes the volumes of packed goods as large as possible with free folding of air-valve from all angles. And it can be recycled.
