Bending stiffness
2-point bending method; bending length and angle depending on sample material
In short — AI-generated
The bending stiffness test measures the resistance of flexible packaging materials against deformation when bent. Using the 2-point bending method according to DIN 53121, a sample strip is clamped at one end and deflected by a defined angle to determine the force required for this movement.
The resulting value indicates the rigidity and mechanical stability of the packaging material. This information is used in practice to ensure that packaging runs smoothly on high-speed filling machines and provides the desired tactile feel or structural integrity for the end product.
