 681M Flex Durability Tester

---

 

It is professionally applicable to the determination of flexural durability of flexible films, composite films and coating films. The instrument can simulate the kneading and folding behaviors of films during production, processing, and transportation.

 

Flex durability can be obtained by measuring changes in pore number or barrier properties after testing, which can provide a quantitative basis for package design and practical use.
