Corrugated board strength requirements
1. Side pressure strength: The maximum force that can be withstood by the corrugated board per unit length in the direction of corrugation.
Side pressure strength = integrated base paper ring strength + integrated corrugated paper ring strength * shrinkage
Generally, the calculation of the side pressure is calculated according to the minimum ring pressure of the base paper (safe and reliable), and the actual test value will be appropriately larger than the theoretical calculation value.
2. Breaking strength: The maximum external force that can be evenly increased before the rupture of corrugated cardboard per unit area.
Cardboard burst strength = paper rupture strength + medium rupture strength + bottom paper rupture strength
