Corrugated paper is a board-like object formed by bonding hanging surface paper and corrugated paper formed by processing corrugated sticks. It is generally divided into single corrugated board and double corrugated board. According to the size of corrugated board, 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 environment-friendly and widely used.


Corrugated board is formed by bonding face paper, inner paper, core paper and corrugated paper processed into corrugated waves. According to the requirements of commodity packaging, corrugated cardboard can be processed into single-sided corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer and eleven-layer corrugated cardboard (as shown in Figures 1, 2 and 3). Single-sided corrugated cardboard is generally used as a lining protection layer for commodity packaging or as a light card or backing plate to protect commodities from shock or collision during storage and transportation. Three-layer and five-layer corrugated cardboard are commonly used in making corrugated boxes. The packaging of many commodities is simple and exquisite through three or five layers of corrugated cardboard. Beautiful and colorful figures and pictures are printed on the surface of corrugated cardboard boxes or corrugated cardboard boxes, which not only protect the internal commodities, but also publicize and beautify the internal commodities. Many corrugated boxes or boxes made of three-layer or five-layer corrugated cardboard have been openly and directly put on the sales counter and become sales packages. The seven-layer or eleven-layer corrugated cardboard is mainly used to make packing boxes for electromechanical, flue-cured tobacco, furniture, motorcycles, large household appliances, etc. In specific commodities, the corrugated cardboard can be combined to form inner and outer case, which is convenient to manufacture and to store, store and transport commodities. With the need of environmental protection and the requirements of relevant national policies, the packaging of such corrugated cardboard products has a tendency to gradually replace wooden cases.
