Corrugated board is a composite board used to make corrugated boxes, which is made of box board and corrugated base paper glued together by a pit machine.

Common for single corrugated board and double corrugated board.

Corrugated board A corrugated board made of two layers of cardboard and a layer of corrugated base paper bonded together. Double corrugated board is made of two layers of box board, two layers of corrugated base paper and one layer of corrugated core paper.

In corrugated paper, the outermost layer of paper is called face paper, the innermost layer of paper is called inside paper, and the uneven corrugated paper in the middle is called pit paper. The paper between the two layers of corrugated paper is called the septum paper.

Corrugated usually has U shape, V shape, UV shape.The top of the U-shaped corrugated is round, good elasticity and good viscosity, but the amount of paper and adhesive is large, the flat pressure elasticity is low, and the recovery function can only be found within the elastic limit, and the excessive pressure can not be restored. V-shaped corrugated is similar to triangular stiffness, poor reduction ability, less paper and adhesive amount, poor bonding ability. UV corrugated has the advantages of the first two, high compressive strength, so this corrugated shape has been widely used.
