TESTEX TB523 Gelbo Flex Tester

Gelbo Flex Tester | Composite Film Rubbing Tester (ASTM F392)

This tester is designed to evaluate the rubbing resistance of various flexible, composite, coated, and similar materials. It effectively simulates the wear, folding, and compression films may encounter during production, handling, transportation, and other stages. By analyzing the changes in the number of pinholes or shifts in barrier properties after testing, this instrument provides valuable quantitative data to assess the film’s durability, offering a practical foundation for optimized packaging design and application.
