Corrugated board has the advantages of compression and shockproof, suitable for printing, easy to form, light weight and environmental protection. Corrugating has good compressive strength and shockproof performance, and can bear certain pressure, impact and vibration. Corrugated board has different structural characteristics, and common types are as follows:

Type A: usually used for transport packaging, used to manufacture cartons for packing fragile items, as well as bushings, cushions and shock absorption elements for products with high requirements for impact, collision and various loads.

Type B: with high rigidity, it can get better printing effect when printing, and it is easy to cut. The packaging of products with enough rigidity and shock absorption protection is not required, such as can, daily chemical products, small package food processing products. Understand the structure of corrugated board and the packaging of hardware and woodwork.

Type C: it has certain rigidity and good shock absorption performance. Its plane compressive capacity is close to that of type B corrugated, and its shock absorption capacity is close to that of type a corrugated.

Type D: most suitable for packing daily goods, household appliances, all kinds of utensils and complete sets of goods.

Type E: it has good two-way stiffness, reduces the impact of external force and surface bending; when the relative humidity of surrounding medium increases, the strength loss of paperboard is less.
