In order to solve this problem, according to the present invention, it is possible to fill all of a large number of partitioned sealing bags continuously in the lateral direction with air from one location, and to seal the sealing bags. To prevent the filled air from coming out of the sealed bag, each sealed bag uses a cushioning material made of a synthetic resin film sheet configured to independently maintain a sealed state. The sealing bag part is bent in the longitudinal direction so that the ends of the cushioning material in the bending direction are joined by welding, and the sealing bag parts located at both ends aligned in the lateral direction are filled with air. The gist of the present invention is that the diameter of the sealing bag is larger than that of the sealing bag located between them.

With this configuration, after the articles to be packaged are stored in the flat buffer packaging bag which is bent into a tubular shape without being filled with air, each sealed bag portion is filled with air to open both ends. Since there is a large-diameter sealed bag part at the position of, the opening area of both end openings is smaller than the cross-sectional area of the storage space surrounded by the sealed bag parts located between the sealed bag parts located at both ends. The article to be packaged can be protected without coming out from the openings at both ends. In addition, if the packaged item is accidentally dropped while it is stored in the cushioning packaging bag, the cushioning packaging bag may drop so that the flat surface of the cushioning packaging bag faces downward, or one of the sealed bag parts located at both ends is lowered. In any case, such as in the case of falling so as to face, the large-diameter sealed bag portions existing in the openings at both ends land, and the impact on the packaged object can be effectively received. Further, the present invention is
When the sealing bag portion is bent in the longitudinal direction so that the cushioning material has a tubular shape, the cushioning packaging bag becomes substantially rectangular in side shape, and further, the cushioning packaging bag storage space portion suitable for the thickness of the packaged object is formed. By forming the partial welds for folding at the appropriate places in the length direction of each sealing bag so that the depth can be obtained, the packaged object is not simply wrapped in a large number of sealing bags, but in a stable state. It becomes possible to provide a cushioning bag which is further excellent in cushioning protection effect, in combination with the above-mentioned constitution in which the opening portions at both ends are provided with the sealing bag portion having a large diameter.
