[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0019] The instant soup bag is a composite of PET, aluminum foil, PA, CPP, PE and other materials, with the characteristics of high temperature resistance, high barrier, strong heat sealing, etc. It is commonly used in three-edge sealing bags, self-standing bags, and suction nozzle bags, etc. It has the functions of easy tearing, display, information marking, etc. in design, and is specially used for packaging instant soup, soup food, etc. It can guarantee the quality and safety of the soup during storage and transportation, and is convenient for consumers to use.

[0020] Based on the technical defects of the prior art that the product is damaged due to continuous friction and collision with the carton when stacked in the carton, please refer to Figs. 1-2The bottom sticking part 4 and the top sticking part 8 are adhered to the inner wall of the carton after unfolding, effectively avoiding the friction and collision between the packaging bag and the carton, and significantly reducing the risk of damage. The packaging bag comprises an upper side edge 1, a side connecting edge 2, a lower side edge 3, a bottom sticking part 4, a cross support bar 5, a connecting support part 6, a top end folding edge 7, a top sticking part 8, and a bottom edge 9. The side connecting edge 2, the lower side edge 3, the bottom edge 9, the bottom sticking part 4, and the connecting support part 6, and the upper side edge 1, the side connecting edge 2, the connecting support part 6, and the top end folding edge 7 all form a cavity structure. The bottom edge 9 is connected between the bottoms of the two lower side edges 3, and the bottom sticking part 4 is connected between the two bottom edges 9. The bottom edge 9 and the bottom sticking part 4 jointly form the bottom structure of the packaging bag. The cross support bar 5 is located in the cavity structure formed by the side connecting edge 2, the lower side edge 3, the bottom edge 9, the bottom sticking part 4, and the connecting support part 6. One end of the cross support bar 5 is fixedly connected with the lower side edge 3, and the other end is fixedly connected with the bottom edge 9. The side connecting edge 2 is in a "V" shape and is connected between the upper side edge 1, the connecting support part 6, and the lower side edge 3. The side connecting edge 2 can be folded or unfolded with the movement of the top end folding edge 7. The upper side edge 1, the side connecting edge 2, and the lower side edge 3 jointly form the side structure of the packaging bag. The top end folding edge 7 is connected with the top of the upper side edge 1 and the connecting support part 6. The top sticking part 8 is fixedly arranged on the surface of the top end folding edge 7. The top end folding edge 7 can be folded inward or unfolded outward relative to the upper side edge 1. The top end folding edge 7 forms the top structure of the packaging bag. In the initial state, the cross support bar 5 is arranged at a small angle and is substantially horizontal. The side connecting edge 2 is in an unfolded state. When the material extrudes the cross support bar 5, the oppositely arranged cross support bars 5 pull the bottom sticking part 4 to be in close contact with each other. When the left and right lower side edges 3 are extruded, the cross support bar 5 is extruded and transmits the extrusion force to the bottom edge 9. Under the combined action of the cross support bar 5, the material extrusion, and the lifting of the bottom edge 9, the bottom sticking part 4 is unfolded. At the same time, when the packaging bag is extruded, the internal air pressure of the packaging bag rises, the connecting support part 6 is lifted upward and makes the top end folding edge 7 unfold, so that the top sticking part 8 is unfolded. Under the action of the bottom sticking part 4 and the top sticking part 8, the packaging bag can be adhered to the inner wall of the carton. At the same time, the top end folding edge 7 can drive the side connecting edge 2 to fold to reduce the overall height of the packaging bag.

[0021] Further, the bottom sticking part 4 and the top sticking part 8 are both two oppositely arranged sheet structures. The two oppositely arranged sheet structures increase the contact area with the inner bottom wall and the inner top wall of the carton, improve the firmness after sticking, ensure that the fixed relationship between the packaging bag and the carton is more stable during transportation, and reduce the relative displacement.

[0022] The existing packaging bag lacks an active fixing mechanism with the carton, and only relies on stacking pressure to maintain position, which is prone to friction and collision during transportation, resulting in damage. Some pasting structures require manual operation to fix, increasing the complexity of the packaging process. To solve this problem, the bottom pasting part 4 and the top pasting part 8 can be pasted with the inner bottom wall and the inner top wall of the carton after being torn open and form a fixed structure. The bottom pasting part 4 and the top pasting part 8 are passively torn open and can be directly pasted with the inner wall of the carton to form a fixed structure, without the need for additional operations to rigidly fix the packaging bag with the carton, thereby fundamentally reducing friction and collision during transportation and reducing the risk of damage. The fixing process is automated, simplifying the packaging process.

[0023] Further, the cross support bars 5 are oppositely arranged and have multiple groups, and the initial angle of the cross support bars 5 is 10°-15°. This can uniformly disperse the material and external pressure, enhance the load-bearing capacity of the bottom structure, ensure that the bottom pasting part 4 is always in stable contact with the bottom of the carton, and improve the support reliability.

[0024] Further, the initial state of the side connecting edge 2 is unfolded, which can be folded by the outer folding of the top folding edge 7 when multiple groups of packaging bags are pressed, so as to reduce the overall height of the packaging bag. The initial unfolded state ensures the capacity of the cavity, and when pressed, it is folded synchronously with the outer folding of the top folding edge 7, actively reducing the overall height, avoiding the problem that the height of the packaging bag is increased when multiple groups of packaging bags are stacked, affecting the sealing of the carton.

[0025] Further, the connecting support part 6 is in the shape of an inverted "V". When multiple groups of packaging bags are pressed against each other, the connecting support part 6 at the top of the packaging bag will be pushed upwards after being pressed, thereby unfolding the top folding edge 7 and facilitating the exposure of the top pasting part 8.

[0026] The existing packaging bag material lacks temperature resistance and oil resistance, and is prone to swelling and leakage when filling soup or containing high-fat content, affecting the safety and service life of the packaging. To solve this problem, the bag body is made of a temperature-resistant and oil-resistant composite film material. The temperature-resistant and oil-resistant composite film material can withstand high-temperature filling processes, resist grease erosion, avoid swelling or leakage of the packaging bag, prolong the service life of the packaging bag, and meet the storage and transportation needs of instant soup.

[0027] It should be noted that the terms "include", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0028] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
