Paper Stiffness Tester

The stiffness tester measures a material's resistance to bending by applying a bending force, and is used to detect the rigidity of materials such as paper and film. During operation, the sample is clamped and a moment is applied, with the bending angle or force value recorded to reflect the material's stiffness. It is applied in quality control in the papermaking and packaging industries.
Selection
When selecting a stiffness tester, it is essential to consider a measurement range that matches the sample thickness, fixtures that are compatible with different materials, and accuracy that meets the testing standard requirements. Additionally, attention should be paid to the ease of instrument calibration and data output formats to ensure user-friendliness in operation and maintenance costs that align with laboratory conditions.
