A Novel Test Method For Predicting Crushing Elasticity In Medium Fluting With Higher Relevance Than The Currently Used Methods Like CMT, PaperCon 2016

During the corrugated board making process the board is passing several rollers and belts, which compress the material more or less. This also happens later in the process when corrugated board sheets are printed, scored and die-cut.

As a damage trouble shooting tool, thickness measurements are not sensitive enough to estimate the amount of crushing in these processes. The loss in thickness will be recovered after the crush and not measurable. The board might lose some of it functionality as packaging protecting its content when it is crushed. Of course a converter doesn’t want that.

Adjustment in the converting process might work for minimize permanent damage of the corrugated board. But it is also important to have strong medium with high resistance to crushing.
