The caliper test is used to validate the thickness of a corrugated board. The thickness of the board correlates with the compressive strength of box.
The thickness of the board is one of the most important performance indicators during production and finished goods. An out of specs thickness may become a quality issue because such condition may be doubted as crushed corrugation or having incorrect flute. Hence, the thickness of board is verified during the product realization.
