[0002] In the process of modern product circulation, corrugated paper boxes are used more and more widely due to their advantages such as easy folding, good cushioning performance, green environmental protection, low cost, and convenient automated production. In the process of industrial product circulation, there are often high requirements for the strength of paper boxes to protect the products from being damaged.

[0003] Corrugated cardboard boxes occupy an important position in my country's packaging market. At present, the three-layer corrugated cardboards are mainly A, B, C, and E.

The existing corrugated cardboards have the same direction of corrugated core paper bonded, and the bending resistance is weak. In practice, it is rare to practice multiple layers of cardboard with mutually perpendicular corrugation directions, and to combine them to produce vertical corrugated boxes.
