[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0027] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0030] In one embodiment of this utility model, according toFigures 1-3 As shown, it includes an outer bag 100 and an inner bag 200 disposed inside the outer bag 100. A buffer cavity 300 is formed between the outer bag 100 and the inner bag 200. A compressible buffer element is provided in the buffer cavity 300. An opening 110 communicating with the buffer cavity 300 is provided on the outer bag 100. The outer bag 100 and the inner bag 200 share a common opening 210. Vacuum compression can be performed in the buffer cavity 300 to reduce its volume. A sealing element is detachably provided on the opening 110.

[0031] Specifically, by setting up a buffer cavity 300 for vacuum compression, the volume of the buffer component can be reduced, making the packaging bag smaller during transportation, facilitating transportation, reducing transportation costs, and at the same time, the buffer component can play the roles of cushioning, shock absorption, and shatter prevention.

[0032] Furthermore, the compression of the buffer chamber 300 can be achieved in two ways. The first method occurs during production, before the outer bag 100 is sealed. At this stage, the packaging bag is compressed by the machine to expel excess gas from the buffer chamber 300. Then, the tail of the outer bag 100 is heat-sealed while the opening 110 is sealed with a sealing element, thus compressing the buffer chamber 300. This compression reduces the volume of the buffer element, allowing for more bags to be transported and lowering transportation costs. Once the packaging bag arrives at the manufacturer's location, the seal is simply opened, air enters the buffer chamber 300, and the buffer element regains its elasticity. After the product is packaged in the inner bag 200, the buffer element within the buffer chamber 300 provides shock absorption and shatterproof protection. The second method involves using a vacuum pump connected to the opening 110 to evacuate air. After creating a vacuum, the opening 110 is sealed with a sealing element, allowing for repeated compression and reuse. It is understandable that the buffer element can be compressed and then rebound.

[0033] In another embodiment of this utility model, according to Figure 2 and 3 As shown, the cushioning element includes several sponge layers 400; these sponge layers 400 are used to protect the inner bag 200. There are two sponge layers 400, which are respectively located on opposite sides within the cushioning cavity 300. Specifically, when using the packaging bag to transport products, it can better protect the products inside the inner bag 200.

[0034] Specifically, the cushioning element is a sponge that can be compressed and rebounded after compression. After rebounding, it has a shock-absorbing and cushioning effect, protecting the product in the inner bag 200.

[0035] In another embodiment of this utility model, according to Figure 2 and 3As shown, a pressure-sealing device is provided at the opening 210 to seal the inner bag 200. The pressure-sealing device includes a convex sealing strip on one side wall of the inner bag 200 and a concave sealing strip 220 on the opposite side wall; the convex sealing strip and the concave sealing strip 220 engage and press together to seal. Specifically, the pressure seal between the convex sealing strip and the concave sealing strip 220 allows for repeated opening and closing, and provides good sealing performance.

[0036] In another embodiment of this utility model, according to Figure 1 As shown, one side of the opening 210 is provided with an extension edge 230, and an adhesive part 240 is provided on the extension edge 230. The extension edge 230 can be folded and fixed to the outer wall of the other side of the opening 210 through the adhesive part 240 to achieve a secondary seal. Specifically, the secondary seal is mainly to prevent the pressure sealing device in the inner bag 200 from accidentally opening during product transportation and the risk of the product falling out of the packaging bag.

[0037] In another embodiment of this utility model, according to Figure 1 As shown, the outer bag 100 comprises an outer layer of vacuum-metallized polyester film and an inner layer of polyethylene film. The inner bag 200 is made of polyethylene film. The vacuum-metallized polyester film has advantages such as high gloss, good oxygen / water vapor barrier properties, and is lighter, more flexible, and less expensive than aluminum foil, while also providing good thermal insulation. The polyethylene film, as the inner layer, provides flexibility, moisture resistance, and a sealing effect.

[0038] In another embodiment of this utility model, such as Figure 1 As shown, the sealing element includes a sealing patch 500; the sealing patch 500 is used to seal or open the buffer cavity 300. When the buffer cavity 300 is in a vacuum compression state, the sealing patch 500 seals the opening 110, allowing the packaging bag to remain compressed. When the sealing patch 500 is opened, air enters the buffer cavity 300, and the buffer element elastically recovers, allowing products to be placed in the inner bag 200 for transportation. The buffer element can play a role in shock absorption, cushioning, and shatter prevention, protecting the products in the inner bag 200 from damage during transportation.

[0039] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
