The first protection walls are on the outer side surfaces of the side walls, respectively. Each of the first protection walls includes two first protection portions, and each first protection portion includes a first protection air column. Each of the first protection portions is attached on the first air column of which the outer surface forms the chamfered shape.

Abstract: A shoulder-filled inflatable bag includes a box body and a cover body. The shoulder-filled inflatable bag can protect the packaged objects, such as a bottle, especially a bottle having shoulders, such as a detergent, a laundry detergent, and etc. In addition to protecting the bottle from external impact, especially the neck of a protective bottle, the shoulder-filled inflatable bag effectively disperses the pressure on the bottle, so that the bottle is not broken due to pressure during transportation or handling.

Abstract: A packaging bag for shockproof includes a bottom wall, a shielding portion, a limiting film and a cover body. Both sides of the shielding portion are adhered to the surface of the bottom wall by heat sealing, and a nesting space is formed between the shielding portion and the bottom wall. The limiting film is stacked above the bottom wall and includes a body and a reversed portion. An accommodation space is formed between a bottom surface of the body, the surface of the bottom wall and the outer longitudinal heat sealing lines, and a limiting space is formed between the top surface of the body, an inner side of the reversed portion and the inner longitudinal heat sealing line. The cover body includes cover air columns located on an upper side of the bottom wall.

Abstract: A gas-sealed bag is formed by two outer films and two inner films. The gas-sealed bag includes a first transversal heat-seal line, a heat-resistant area, a second transversal heat-seal line, gas inlets, and longitudinal heat-seal lines. The second transversal heat-seal line includes protrusions and bottoms. The protrusions are in the heat-resistant area, and the bottoms are out of the heat-resistant area. The transversal heat-seal lines form an inflation channel, and one end of the inflation channel includes an inflation port. The gas inlets are formed at positions coating a heat-resistant material and corresponding to the protrusions. A gas storage chamber is formed between each two adjacent longitudinal heat-seal lines. Accordingly, additional heat-seal nodes are not necessary to be provided on outer sides of the inner films and inner sides of the outer films for facilitating the inflation port to open. Therefore, manufacturing steps for the gas-sealed bag can be reduced.
