Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboards, and more specifically to a moisture-proof corrugated paperboard. Background Art

[0002] Corrugated cardboard is a material consisting of a corrugated paper core sandwiched between two layers of flat cardboard. Corrugated cardboard is usually used to make cartons, paper boxes, packaging filling materials, etc. It is widely used in various industries such as electronic products, food and beverages, daily necessities, and medicine.

[0003] The existing corrugated cardboard still has the following problems: the existing corrugated cardboard is a pure paper structure and its moisture-proof performance is not ideal. When used in a relatively humid environment, the carton is very easy to absorb moisture and become damp, which will undoubtedly affect the overall supporting strength of the carton. Moreover, the fire-retardant performance of the existing corrugated cardboard is not ideal. Since the pure paper structure is very flammable during use and lacks certain safety performance, it brings many inconveniences to use.

[0004] In addition, corrugated cardboard is often used as a carton to package, transport and store materials. During transportation and storage, it will be placed in a carriage or on the ground, and the bottom of the corrugated cardboard will come into contact with the ground or the floor inside the carriage. The ground is often very humid, which can easily cause the bottom of the corrugated cardboard to get damp or even moldy. In addition, during transportation and use, the corrugated cardboard lacks certain anti-slip properties, which makes it easy for it to shake and shift during transportation, thereby causing collisions. When collisions occur, it is difficult for the existing corrugated cardboard to achieve good cushioning performance relying solely on a pure paper structure, which brings many troubles to use.

[0005] In view of this, we propose a moisture-proof corrugated cardboard. Utility Model Content
