Paper and Cardboard Crease Stiffness Meter
The Paper and Cardboard Crease Stiffness Meter is used to measure the bending stiffness and folding-related stiffness of low-grammage paper and cardboard, as well as films, plastics, wire, metal sheets, and composite materials. The instrument allows users to adjust the test direction, test spacing, bending angle, angular speed, and bending time according to test requirements. With a measuring range of 0–1000 g (0–10000 mN), it is suitable for packaging and printing companies, research institutions, and quality inspection departments.
