[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper interlayer (commonly known as "corrugated sheet", "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and a layer of cardboard (also known as "box board", "box board"). It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.

[0003] In order to improve its strength, multiple layers of corrugated core paper are generally used, and strip additives such as cotton strips, strip paper tubes and the like are added to the concave parts of the corrugated core paper. Although the strength is improved, adding additives to the concave parts of the corrugated core paper may easily affect the cushioning performance, resulting in a decrease in the cushioning effect.
