Paper bending stiffness tester,also known as folding resistance tester, MIT stiffness test machine,used to measure paper with a thickness less than 0.25mm, tensile strength greater than 1.33kN/m, and paperboard and other sheet materials with a thickness of (0.25~1.40)mm. Folding fatigue strength, assessing the flexibility and elongation characteristics of the material.Paper Bending stiffness tester is suitable for the determination of folding resistance of various paper and paperboard. It is an ideal test equipment for industries and departments such as papermaking, packaging, scientific research and product quality supervision and inspection.
