Stiffness

The crease stiffness test is carried out in the paper and packaging industries to measure the board stiffness and crease recovery of materials like paperboard and printed cartons.

Specialised instruments like the CBT1 Crease and Board Stiffness Tester help board manufacturers and printing and packing companies determine the force required to bend a sample at specific angles. They also help predict the ‘runability’ of a sample board or finished carton, ensuring optimum packaging line speeds and quality control.
