[0032] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will combine the specific embodiment of the application, and refer to the drawings, clearly and completely describe the technical scheme of the utility model.

[0033] As shown in Figure 1 and Figure 3 A graphene composite packaging bag, comprising: a packaging bag body 1, the upper part of the packaging bag body 1 is provided with a concave-convex buckle 2 and a pulling part 4.

[0034] The packaging bag body 1 is sequentially arranged from outside to inside: an outer layer 101, an intermediate layer 102 and an inner layer 103, and an adhesive layer 104 is arranged between adjacent film layers and is hot-pressed and bonded.

[0035] The outer layer 101 is sequentially arranged from outside to inside: a polyethylene film 1011 and a polytetrafluoroethylene film 1012.

[0036] The inner layer 103 is sequentially arranged from outside to inside: a graphene reinforcing layer 1031 and a graphene antibacterial layer 1032, and the inner side surface of the graphene antibacterial layer 1032 is provided with a wave-shaped anti-sticking pattern 1033.

[0037] The polyethylene film 1011 of the outer layer of the graphene composite packaging bag has good flexibility and elasticity, can adapt to the packaging of articles of different shapes and sizes, and the high-density polyethylene film 1011 can effectively prevent scratches on the outer surface of the packaging bag, causing damage; the graphene antibacterial layer 1032 of the inner layer has good antibacterial performance and can inhibit the growth and reproduction of bacteria, fungi and other microorganisms. When packaging food, medicine and other articles susceptible to microbial contamination, the graphene antibacterial layer can effectively prevent the growth of microorganisms and maintain the quality and safety of the contents. The wave-shaped anti-sticking pattern 1033 increases the roughness of the inner side surface of the graphene antibacterial layer 1032, thereby effectively preventing the contents from adhering to the inner wall of the packaging bag; and the anti-sticking pattern 1033 increases the surface area of the graphene antibacterial layer 1032, which can effectively improve its antibacterial ability.

[0038] In one specific embodiment, the graphene reinforcing layer 1031 is made of graphene oxide, and the graphene antibacterial layer 1032 is made of multilayer graphene.

[0039] like Figure 3 As shown, the intermediate layer 102 consists of, from the outside to the inside, a polyester film 1021 and an elastic layer 1022.

[0040] In one specific embodiment, the interior of the elastic layer 1022 is filled with elastic particles.

[0041] Polyester film 1021 possesses high tensile strength and modulus, along with good stiffness. This allows the packaging bags to maintain their shape well during daily use, resisting deformation and ensuring their appearance quality and stability. The elastic layer's elasticity allows the packaging bags to better adapt to items of different shapes and sizes. When packaging irregularly shaped items, the elastic layer can deform to conform to the item's surface, providing a tighter wrap and protection.

[0042] As shown in the figure, the buckle 2 is disposed between two adjacent side walls of the inner cavity of the packaging bag body 1, and is used to seal the upper opening of the packaging bag body 1.

[0043] like Figure 2 As shown, each of the adjacent sidewalls of the main body 1 of the packaging bag is provided with an extension 3 above the buckle 2, and the extension 3 is fixedly connected to the lower part of the lifting part 4.

[0044] An extension 3 located on the upper part of the buckle 2 on the adjacent sidewall of the main body 1 of the packaging bag is fixedly connected to the lower part of the lifting part 4. The extension 3 serves as a transition and reinforces the connection. It increases the connection area and strength between the lifting part 4 and the main body 1 of the packaging bag, allowing the force to be more evenly distributed on the sidewall of the main body 1 of the packaging bag when the lifting part 4 bears weight. This reduces stress concentration at the connection between the lifting part 4 and the main body 1 of the packaging bag, lowers the risk of tearing or damage at the connection, and thus improves the stability and durability of the entire packaging bag structure.

[0045] like Figures 1-2 As shown, a rivet 5 is provided between the extension 3 and the corresponding lifting part 4.

[0046] The rivets 5 provided between the extension 3 and the corresponding lifting part 4 further strengthen the connection between them. The rivet 5 connection has high reliability and stability, and can withstand large tensile and shear forces, ensuring that the lifting part 4 will not separate from the extension 3 during frequent use, thereby improving the service life and safety of the packaging bag, and is especially suitable for situations that require repeated lifting and handling of heavy items.

[0047] like Figures 1-2As shown, the middle part of the pulling part 4 is provided with a hand holding cavity 401. The hand holding cavity 401 provided in the middle part of the pulling part 4 is ergonomically designed, which is convenient for the user to put fingers into it and provides a comfortable holding space, so that the action of pulling the packaging bag is more natural and easy, the fatigue of the hand is reduced, and the comfort of use is improved.

[0048] As shown in the drawings, Figures 1-2 As shown, the upper part of the hand holding cavity 401 is provided with a flexible pad 402, and the flexible pad 402 is fixedly connected with the pulling part 4. The flexible pad 402 provided in the upper part of the hand holding cavity 401 is fixedly connected with the pulling part 4, and the flexible pad 402 has the characteristics of softness and elasticity. When the user pulls the packaging bag, the flexible pad 402 can buffer the pressure between the hand and the pulling part 4, avoid the hand from being painful or having a pressure mark due to long-time contact with the hard material of the pulling part 4, and further improve the comfort of use, especially when carrying heavy objects, the buffering effect of the flexible pad 402 is more obvious.

[0049] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the art, without departing from the creative concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
