[0002] Corrugated cardboard is a plate-like material made of noodle paper and corrugated rollers. Generally, corrugated rollers are used to form corrugated paper in a wavy shape. The core paper interlayer of the corrugated cardboard has good stability and deformation resistance, which can ensure that the corrugated cardboard has greater mechanical strength. Corrugated cardboard usually has three, five or seven layers, which makes the corrugated cardboard have good stability and deformation resistance.

[0003] The prior art discloses a corrugated cardboard with patent announcement number CN214529961U, which comprises at least one layer of face paper and at least one layer of corrugated core paper. One or more stress-bearing belts are arranged inside the corrugated cardboard, and the direction of the stress-bearing belts is perpendicular to the flute direction of the corrugated cardboard. The stress-bearing belts of the utility model are arranged inside the corrugated cardboard and produced together with the cardboard, which can reduce the production process and equipment cost. In addition, one or more stress-bearing belts are arranged as needed, which can effectively improve the strength of the corrugated cardboard and reduce the damage of the cardboard. However, the following deficiencies still exist in actual use: from a practical point of view, the existing corrugated cardboard has a fixed size. When in use, since the surrounding sides are exposed to the outside, the external humid air can easily enter the inside of the corrugated cardboard through the surrounding sides, affecting the service life of the corrugated cardboard.

[0004] Therefore, a corrugated paperboard structure with moisture-proof function is needed to solve the problem in the prior art that the corrugated paper is exposed on all sides, and the external humid air can easily enter the inside of the corrugated paper through the sides, thus affecting the service life of the corrugated paper.
