Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper, in particular to a corrugated paperboard with a three-corrugated paper core. Background Art

[0002] Corrugated paper is a board-shaped material made by gluing noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into two categories: single corrugated paperboard and double corrugated paperboard. According to the size of the corrugation, it is divided into five types: A, B, C, E, and F. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used.

[0003] Although the existing corrugated paper has the advantages of light weight, easy processing, convenient storage and transportation, it is essentially made of "paper" as the basic raw material. Therefore, the corrugated paperboard is not only easy to be punctured by external sharp objects or when the objects stored inside are relatively sharp, the corrugated paperboard is also easy to be punctured; in addition, the corrugated paperboard does not have good fireproof and flame retardant properties. Once affected by external open flames, the corrugated paperboard is easy to burn. In summary, the existing corrugated paperboard still has the following problems:

[0004] 1. Corrugated cardboard is easily pierced by sharp objects; 2. Corrugated cardboard has poor fire resistance and flame retardancy and is easily affected by external open flames. Utility Model Content

[0005] The main purpose of the utility model is to provide a corrugated paperboard with a three-corrugated paper core, which can effectively solve the problems in the background technology.
