Flexible films and coated materials are exposed to repeated mechanical stress every day. Continuous bending, torsion and compression can cause microcracks and pinholes — increasing the risk of product loss and reduced shelf life.

With the Rycolab Flex Testers, you can assess flex durability in a targeted, reproducible way, fully compliant with international standards.

Rycolab Gelbo Flex Durability Tester (RL-GF-A)
This system automates the ASTM F392 “Gelbo” flex test, combining 440° torsion and 65 mm compression at 45 cycles per minute. It enables fast and reliable detection of pinholes and cracks in barrier films and coatings.

• Flexible barrier films (PE, PP, PET, EVOH)
• Coated films
• Medical and industrial packaging

Rycolab Crumple Flex Tester (RL-CF-A)
Designed to simulate repeated bending and crumpling of coated fabrics through controlled 90° torsion and axial compression. Ideal for quality control and product development, with a focus on coating durability and water resistance.
