3. Comply with ASTM Standards: Meets the ASTM F392 standard for evaluating flex durability of flexible barrier materials, ensuring international compliance.

4. Reduce Failure Rates: Helps predict and eliminate weak points in material design and processing, saving time and resources in product development.

5. Cross-Industry Applications: Ideal for industries where packaging integrity, product safety, and long shelf life are essential.

Applications of Material Flex Crack Resistance Tester

The Material Flex Crack Resistance Tester is commonly used to test:

• Flexible packaging films for snacks, frozen foods, and pharmaceuticals

• Barrier films and laminates for medical device packaging

• Plastic-coated materials used in beverage and dairy cartons

• Pharmaceutical blister packs requiring sterile barrier performance

• Industrial films and wraps for automotive or electronics protection

This instrument is widely adopted by packaging manufacturers, material suppliers, food and beverage companies, medical product companies, and university research labs that focus on product development, material engineering, and quality assurance.

Working Principle

The working principle of the Material Flex Crack Resistance Tester is based on a combined twisting and horizontal motion that mimics real-world mechanical stress. A rectangular sample (280 mm x 200 mm) is mounted between two mandrels. As the mandrels twist (440°) and move horizontally (65 mm), the material undergoes simultaneous torsional and compressive flexing. This repetitive strain can lead to the formation of microscopic cracks or pinholes, which compromise material integrity.

By monitoring the occurrence of flex failure through pinhole detection or permeability changes, manufacturers can assess a material’s suitability for specific end-use applications.
