Der Knautschflex-Tester is a precision testing instrument designed to evaluate the crumple resistance and flexural strength of materials. Used primarily in industries like packaging, textiles, and paper production, this tester simulates the mechanical stresses that materials face during handling, transportation, or packaging processes. By applying consistent flexing and crumpling forces, it provides a clear indication of a material’s durability and its ability to withstand deformation.

The Crumple Flex Tester is compliant with ISO 7854, a global standard that outlines the procedures for testing the crumple resistance of materials, ensuring reliability, repeatability, and industry compliance.
