Crease & Stiffness (Round or 90 degrees) Tester Series

Crease & Stiffness (Round or 90 degrees) Tester Series

To measure uniformity and correctness for paper, carton board, printing, and packaging materials, crease and stiffness testing plays a key role. For better performance of cartons on high speed packaging machines, and when manual folding is required, board stiffness and crease recovery (spring back) is necessary. Moreover, the value of crease stiffness is technically important in the folding of carton blanks during their erection and closure.

Crease recovery can be determined when there is reduction in resistance, which is offered by creased board after it, is folded 90° at the crease measuring the recovery force after 15 seconds. Board Stiffness is determined by bending a 50mm length of board through a 15° angle.

The C0039-M2 model offers added functionality of being able to test for round corner creases. Any corner crease can be tested with the easily changeable Round Corner Jaw.
