Flex Durability Testing
The flex durability is the ability of a material to resist flexing or kneading during production and transportation. Permeability test often comes after the flex process to ensure the overall performance of packaging materials.
- ASTM F392 - Standard Test Method for Flex Durability of Flexible Barrier Materials
1364 - Field 'categories_id' doesn't have a default value
insert into prodandcate set products_id='1850', products_name='FDT 02 Flex Durability Tester', products_description='FDT-02 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 would be obtained by measuring the changes in number of pinholes or barrier properties after test, which could provide quantitative basis for package design and practical usage.
