Model 79-25 is a user-friendly microprocessor controlled instrument to determine the bending resistance of paper, paperboard, plastic film, medical tubing, and wire. Bending stiffness is a characteristic associated with the rigidity of a material. This property is related to the modulus of elasticity of the material's stiffness. Our Bending Tester was originally developed to produce a more concise, consistent measurement for the paper industry. This property is now used in a variety of industries including personal products, paper, flexible films, packaging and non-wovens.
