Classification of corrugated cardboard

Corrugated cardboard is made by bonding paper, paper, core paper and corrugated paper processed into corrugated corrugations.

According to the demand for product packaging, corrugated board can be processed into single-sided corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, and eleven-layer corrugated cardboard.

Different corrugated corrugated shapes and bonded corrugated cardboard have different functions.

Even if the same quality of facial paper and paper is used, the performance of the corrugated paperboard formed has a certain difference due to the difference in shape.

At present, there are four commonly used corrugated shapes in the world. They are type A, type C, type B, and type E. Their technical specifications and requirements are shown in Table 1.

The corrugated paperboard made of A-type crucibles has good cushioning properties and is full of certain elasticity. C-type crucibles are inferior to A-type crucibles. However, the stiffness and impact resistance are better than that of the A-type crucible; the arrangement density of the B-type crucible is large, and the corrugated paperboard made of a flat surface has a high bearing pressure and is suitable for printing; the E-type crucible is thin and dense, but also presents its rigidity. strength.
