Crease and Stiffness Tester C0039

To measure correctness and uniformity of carton board, printing, paper, and packaging materials, crease and stiffness testing plays a key role. To determine the performance of cartons on high speed packaging machines and manual folding, board stiffness and crease recovery (spring back) is important.

Furthermore, the value of crease stiffness is technically important in the folding of carton blanks during their erection and closure. The crease recovery (spring back) can result in forces, which distort the erected carton or cause stresses to be applied to closures, which reduce their effectiveness.

Crease recovery can be determined by the decrease in resistance 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.
