[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] This utility model provides an embodiment: Please refer to Figures 1-4 A wear-resistant and waterproof corrugated cardboard packaging box includes a box body 1. Reinforcing strips 2 are provided at each of the four corners of the inner cavity of the box body 1. The reinforcing strips 2 can be glued to the box body 1. The top and bottom of the reinforcing strips 2 are flush with the top and bottom of the inner cavity of the box body 1. Through the reinforcement strips 2, during the sealing process, the inner cover of the packaging box can be supported, preventing sagging and ensuring a tight fit between the outer cover and the inner cover, thus guaranteeing a seal between them. Furthermore, the reinforcing strips 2 also support the box body 1, improving its resistance to deformation.

[0019] The reinforcing strip 2 has an inwardly concave arc shape on the side away from the box body 1. This arc-shaped section of the reinforcing strip 2 transitions smoothly with the inner wall of the box body 1, ensuring the smoothness of the inner wall lines and facilitating use. The reinforcing strip 2 has evenly distributed water-permeable micropores and a hollow structure. Its inner cavity is filled with absorbent particles 10. These particles absorb moisture from inside the box during use, reducing the probability of mold growth on the contents. The absorbent particles 10 can be made of absorbent resin, preventing backflow and excessive water absorption. The amount and material of the absorbent particles 10 can be customized as needed and are not limited here.

[0020] A corrugated paper layer is provided in the middle of the cross-section of the packaging box body 1. The corrugated paper layer includes a face paper layer 6, a corrugated paper layer 8, and an inner paper layer 7. Support strips 9 are connected to the inner sides of both the face paper layer 6 and the inner paper layer 7. The support strips 9 can be connected to the face paper layer 6 or the inner paper layer 7 by adhesive. The type of adhesive can be selected according to the requirements and is not limited here. The recesses of the corrugated paper layer 8 are filled by the support strips 9. The support strips 9 improve the compressive strength of the corrugated paper layer and extend its service life. The support strips 9 can be made of rubber.

[0021] A cushioning layer 3 is provided on the outer side of the corrugated paper layer. The corrugated paper layer and the cushioning layer 3 can be bonded together using adhesive. The type of adhesive can be selected according to requirements and is not limited here. Both the face paper layer 6 and the inner paper layer 7 have raised strips 11 on their outer sides. The side of the cushioning layer 3 closest to the corrugated paper layer has a groove that matches the raised strips. Through the setting of the raised strips 11 and the groove, the corrugated paper layer and the cushioning layer 3 can be in a snap-fit ​​state, improving the reliability of the bond between the corrugated paper layer and the cushioning layer 3. The cushioning layer 3 can be made of rubber, so that the cushioning layer 3 has both cushioning and waterproof properties.

[0022] A waterproof layer 4 is provided on the outside of the buffer layer 3. The buffer layer 3 and the waterproof layer 4 can be bonded together with an adhesive. The type of adhesive can be selected according to the requirements and is not limited here. In some embodiments of this application, the waterproof layer 4 includes a paper base layer. The paper base layer is impregnated in a waterproof coating so that the waterproof coating is distributed in the fiber gaps and on its surface. The waterproof layer 4 is formed after the impregnated paper base layer is dried. The type of waterproof coating and the drying time can be set according to the requirements and are not limited here.

[0023] A wear-resistant layer 5 is provided on the outer side of the waterproof layer 4. The waterproof layer 4 and the wear-resistant layer 5 can be bonded together using an adhesive. The type of adhesive can be selected according to requirements and is not limited here. Wear-resistant particles are uniformly distributed on the outer surface of the wear-resistant layer 5. The wear-resistant particles improve the wear resistance of the wear-resistant layer 5. A reflective layer is provided on the inner surface of the wear-resistant layer 5. The reflective layer can reflect external heat and reduce the impact of external ambient temperature on the internal environment of the packaging box. In some embodiments of this application, the wear-resistant layer 5 is made of kraft paper. Those skilled in the art can use an electrostatic sand-coating process to embed wear-resistant particles (such as silicon carbide) into the surface of the kraft paper. The specific operation steps are existing technology and will not be described in detail here. A reflective layer is provided on the inner side of the kraft paper, which can be achieved by hot pressing or adhesive bonding to combine the high-temperature resistant aluminized film with the kraft paper.

[0024] In summary, when using this wear-resistant and waterproof corrugated cardboard packaging box, the reinforcing strip 2 supports the inner flap, preventing it from sagging. This allows the outer flap to fit tightly against the inner flap, ensuring a tight seal between them. The reinforcing strip 2 also improves the box's compressive strength. The wear-resistant layer 5 enhances the box's abrasion resistance, and the reflective layer on the inner side of the wear-resistant layer 5 reflects heat, reducing the impact of external ambient temperature on the internal environment. The waterproof layer 4 and the buffer layer 3 work together to achieve waterproofing, improving the box's waterproof performance. Furthermore, the buffer layer 3 reduces the force applied to the box, improving its compressive strength and lowering the breakage rate of the corrugated cardboard packaging box.
