Product Description

TMI Crease and Board Stiffness tester is useful to industries of carton board, paper, printing and packaging. The relationship between board stiffness and crease recovery (spring back) is an important factor in the performance of cartons on high speed packaging machines and in manual folding. It is crucial to have the creases in boards correct and uniform. The crease recovery (spring back) can result in forces, which distort the carton or cause stresses to be applied to closures, which reduce their effectiveness.

In TMI Crease and Board Stiffness tester, Board stiffness is determined by bending a 2 in (50mm) length of board through a 15° angle. Crease recovery is determined by holding a formed crease at 90° and measuring the recovery force after 15 seconds. This instrument measures the bending resistance of the board and evaluates commercially formed creases. With interchangeable jaws to test square corner packs and round corner packs. The sample is griped in jaws and rotated through a set angle, the force transmitted through the sample is measured. To assist in accurate cutting of sample specimens, a Crease and Board Stiffness cutter is included.
