[0020] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] Reference Figure 1 , Figure 2 and Figure 3The utility model embodiment is a high-strength anti-seepage composite corrugated paperboard, which includes a buffer layer 1. The buffer layer 1 is foam. The buffer layer 1 is made of high-quality foam material and has good buffering and shock-absorbing performance. In the corrugated paperboard, it is mainly used to absorb and disperse external impact forces to protect the items inside the package from damage. The upper paper layer 2 and the lower paper layer 3 are respectively arranged on both sides of the buffer layer 1. The structure of the lower paper layer 3 is the same as that of the upper paper layer 2. The two structures are the same and symmetrical to each other, and together constitute the main part of the paperboard. The upper paper layer 2 includes two paperboard layers 5, a corrugated core layer 7 disposed between the two paperboard layers 5, a plurality of connection grooves 6 and a plurality of support paperboards 8. The plurality of connection grooves 6 are equidistantly disposed inside the two paperboard layers 5 on the opposite side. In order to enhance the connection strength between the paperboard layer 5 and the corrugated core layer 7, the corrugated core layer 7 is bonded to the connection grooves 6. The plurality of support paperboards 8 are equidistantly fixedly connected to the opposite side of the two paperboard layers 5. In order to further enhance the overall strength of the paperboard, the ends of the plurality of support paperboards 8 opposite to the corresponding paperboard layer 5 are in contact with the corresponding end points of the corrugated core layer 7, forming a stable support structure.

[0022] A reinforcing layer 4 is bonded between the paperboard layer 5 near the buffer layer 1 and the buffer layer 1. The reinforcing layer 4 is made of high-strength kraft paper, and has excellent folding resistance, pressure resistance and water resistance, which not only improves the overall strength of the paperboard, but also enhances the anti-seepage ability of the paperboard. The outer surface of the other paperboard layer 5 is provided with a waterproof coating 9, which is a tetrafluoroethylene film. The waterproof coating 9 is made of a tetrafluoroethylene film material and has excellent waterproof performance. It can effectively prevent moisture from penetrating into the inside of the paperboard and protect the internal items from moisture and mildew.

[0023] Working principle: By setting the buffer layer 1 as the base layer of the paperboard, it has good buffering and shock-absorbing performance. In the corrugated paperboard, it is mainly used to absorb and disperse the external impact force to protect the items inside the package from damage; and setting the connection groove 6 inside the paperboard layer 5 to bond with the corrugated core layer 7 can increase the connection area between the paperboard layer 5 and the corrugated core layer 7, thereby enhancing the connection strength between the paperboard layer 5 and the corrugated core layer 7; and setting the supporting paperboard 8 and the corrugated core layer 7 to form a stable supporting structure can further improve the overall strength of the paperboard;

[0024] A reinforcing layer 4 with excellent folding resistance, pressure resistance and water resistance is arranged between the paperboard layer 5 and the buffer layer 1, which not only improves the overall strength of the paperboard, but also enhances the anti-seepage ability of the paperboard. At the same time, a waterproof coating 9 is arranged on the outermost side to effectively prevent moisture from penetrating into the inside of the paperboard, protecting the internal items from moisture and mildew.

[0025] The overall strength and anti-seepage performance are both improved. It can not only effectively protect the internal items from external impact and vibration, but also prevent moisture penetration. It is a packaging material with excellent performance and strong practicality.

[0026] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
