    摘要： The buffer packing bag comprises an air-supplying passage, which is made of plastic films placed one on another and bonded at desirable spots, and an air-inflatable section formed beside the air-supplying passage, which is divided into individual air-inflatable parts, formed by heat-bonded at multiple spots, and check valves, which allow and stop air flow between each of individual air-inflatable parts and the air-supplying passage, and space-making folds, made in both of the divided portions of the air-inflatable section by heat-bonding to make at least two lines in each portions crossing the individual air-inflatable parts, with the formation to make a loading slit by folding inward from both of the width ends along the length side of the base and heat-bonding both of the overlapped areas of the length sides.
