Even if the same quality of face paper and lining paper is used, the performance of the corrugated cardboard is also different due to the difference in corrugated shape. Their technical indicators and requirements are shown in Table 1. The corrugated board made of A-type corrugated has better buffering properties and a certain degree of elasticity, and C-type corrugated is second than A-type corrugated. However, the stiffness and impact resistance are better than A-type corrugated; B-type corrugated cardboard has a large arrangement density, and the corrugated board has a flat surface and high bearing pressure, which is suitable for printing; E-type corrugated is thin and dense, showing its rigidity. strength.
