Abstract

Folding performance is very important in box manufacturing process using paperboard. To evaluate the folding performance of various paperboards, we measured the folding moment and folding behavior at the different folding angle and rate conditions. When linerboard with grammage of $300\;g/m^2$ was folded up to $90^{\circ}$, the compression break and delamination of sheet were observed. The maximum folding moment was little affected by folding angle, but it was increased logarithmically with folding rate. And the effect of paperboard thickness was significant. The maximum folding moment of MD sample was higher than one of CD sample by 40%.
