Please refer to Fig. 2 at the same time: Fig. 2 is a cross-sectional schematic diagram drawn by taking a single air chamber 10, the external hanging gas packaging bag 1 is composed of two layers of films, respectively an upper film 21 and a lower film 22, and the two layers of films are Films made of materials such as plastic or plastic. In addition, the air valve composed of upper and lower air valve membranes 25, 26 is sandwiched between the aforementioned upper and lower membranes 21, 22 with an appropriate width. The air valve device formed by the upper and lower air valve films 25, 26 extends downwards to a predetermined width from one end of the external gas packaging bag 1, that is, at the position of the air inlet 14, and the width only needs to match the position of the air valve device. The length of the heat-sealing line is sufficient and does not need to be equal to the length of the upper and lower films. The periphery of the film is heat embossed with a copper mold to form a heat seal line 35, so that the external hanging gas packaging bag 1 can be sealed and the gas will not leak out. Several air chambers 10 are formed by heat embossing the heat-seal line 31 between the air chambers 10 . Please refer to Figures 1 and 2 at the same time: the air valve device is provided with two non-parallel heat-sealing lines 32, and the upper film 21, the upper air valve film 25, and the lower air valve film 26 are heat-sealed together in three layers, so that The space surrounded by the upper and lower air valve films 25, 26 and two non-parallel heat-sealing lines 32 defines an air inlet 36. For avoiding that upper and lower air valve films 25,26 are heat-sealed together in the manufacturing process of pressing and heat sealing, a heat-resistant printing 33 is set between the upper and lower air valve films 25,26 so that the air inlet 36 will not be heated. Sealed together to facilitate the inflation operation. In addition, in order to strengthen the sealing of the air chamber 10, two oblique heat-sealing lines 39, 39 are installed obliquely outward at the aforementioned two non-parallel heat-sealing lines 32 to strengthen the sealing of the air chamber 10 and avoid air leakage. .
