Gelbo Flex Durability Tester Compliance with ASTM F392

“The Gelbo Flex Durability Tester is an essential instrument used to evaluate the flex resistance and integrity of flexible films, laminates, and barrier materials. Compliance with ASTM F392, a widely recognized test method, ensures accurate and standardized testing results.”

What is Gelbo Flex Durability Tester?

The tester is designed to simulate real-world mechanical stresses that flexible packaging materials encounter during handling, transportation, and storage. The instrument performs repetitive twisting and compression cycles on test samples to determine their resistance to flex fatigue and potential pinhole formation. By identifying material weaknesses early, manufacturers can optimize packaging performance and improve product shelf life.

ASTM F392 – Standard for Flexible Packaging Durability Testing

ASTM F392 is the standard test method that defines procedures for evaluating the flex durability of flexible barrier materials. This method specifies key parameters such as:

• Test Conditions: Number of flex cycles, frequency, and amplitude
• Sample Preparation: Size and mounting requirements
• Evaluation Criteria: Presence of pinholes, cracks, or material degradation
  By following ASTM F392, manufacturers ensure consistency in test results and compliance with industry standards.

Why Use a Gelbo Flex Durability Tester?

The Gelbo Flex Durability Tester is widely adopted due to its advantages in packaging quality control, including:

• Accurate Material Evaluation: Detects weak points in flexible films before mass production.
• Regulatory Compliance: Ensures packaging meets ASTM F392 and industry standards.
• Cost Reduction: Helps prevent product failures, reducing material waste and recalls.
• Versatile Applications: Suitable for food packaging, pharmaceuticals, medical devices, and more.

How to Perform a Gelbo Flex Test?

1. Sample Preparation: Cut a specified size of the flexible film and mount it on the tester.
2. Test Setup: Adjust the tester settings according to ASTM F392 requirements.
3. Flex Testing: The instrument applies repeated twisting and compression movements.
4. Inspection: Examine the sample for pinholes, cracks, or loss of barrier properties.
5. Data Recording: Analyze the test results to assess material performance.
