ASTM F392 Flex Durability Tester GelboFlex Packaging Flex Film Flex Failure Tester High Quality China Product

The ASTM F392 Flex Durability Tester is a precision-engineered laboratory instrument designed to evaluate the flexural resistance of flexible barrier materials. This high-performance tester simulates repeated strain and mechanical stress to detect potential failure points such as pinholes or material fatigue. Commonly referred to as the GelboFlex Tester, it is a vital tool for manufacturers in the packaging, medical, food, beverage, and pharmaceutical industries seeking to ensure the integrity and durability of flexible films, laminates, and coated materials.

As per the ASTM F392 standard, this tester is crucial for quality assurance processes, especially for flexible packaging used in moisture-sensitive or contamination-sensitive products. It ensures that the material can withstand real-world mechanical stress, such as handling, shipping, and storage conditions.

Key Applications of ASTM F392 Flex Durability Tester

The ASTM F392 Flex Durability Tester is widely used across several industries:

• Food Packaging: Ensures flexible barrier materials resist pinhole formation during transit and handling.

• Medical and Pharmaceutical Packaging: Confirms material integrity for sterile environments.

• Flexible Films and Coatings: Tests multilayer composites for resistance against flexural fatigue.

• Research & Development Labs: Offers data-backed insight into material performance and new material innovations.

• Quality Assurance Departments: Helps maintain compliance with international standards like ASTM F392.

Test Principle of ASTM F392 Flex Durability Tester

The ASTM F392 Flex Durability Tester operates by attaching a sample (280 mm x 200 mm) to the machine’s flexing mandrels. It then subjects the sample to a repetitive combination of twisting and horizontal compression movements. This process mimics the actual mechanical strain flexible packaging undergoes in real-life handling situations.

• The machine applies a twisting motion of 440º within the first 90 mm of the stroke.

• Followed by a horizontal motion with a stroke length of 65 mm.

• The test cycle operates at a speed of 45 cycles per minute.

This dual-action movement simulates accelerated wear, revealing potential pinholes or material fractures, which are critical failure indicators for barrier materials.

Test Method According to ASTM F392 Standard

The ASTM F392 test method involves:

1. Preparing the sample according to the specified dimensions.

2. Mounting it securely to the flexing mandrels.

3. Setting the appropriate test condition (A–E) based on the product application.

4. Running the flex cycles as per defined parameters.

5. Inspecting the sample post-test under light or using dye penetration to detect pinholes.

This method ensures consistent, reliable, and standardized data for quality control teams and R&D departments.
