Damage to the flute during production is difficult to determine. Loss of box strength due to crushingoccurs in nearly all box plant operations.

Impacts on corrugated board during manufacturing and converting also contribute to loss of box strength.This useful method provides a means to measure the degree of damage allowing box makers to determine the sourceand cause of excessive corrugated board crush.
