C681M Flex Durability Tester

C681M Flex Durability Tester is professionally applicable to the determination of flex durability of flexible films, composite films and coating films. The instrument can simulate the kneading and creasing behaviors of films happened during production, processing and transportation. The flex durability can be obtained by measuring the changes in number of pinholes or barrier properties after test, which can provide quantitative basis for package design and practical usage.

Basic Applications Flexible Films, Composite Films and Coating Films
Including plastic films, sheets and composite films e.g. composite films, aluminized films, aluminum plastic composite films, nylon films and coating films for food or drug packages
Paper Materials
Test the flex durability of paper materials
