جهاز اختبار GFT Gelbo Flex

The Gelbo Flex Tester is an essential instrument for evaluating the flex durability of flexible barrier materials, such as films, composites, and coating films. This device tests a material’s ability to withstand repetitive strain, which is crucial for preventing flex cracks and ensuring the integrity of packaging during distribution. Flex crack resistance is a vital property, as it minimizes the risk of package perforation, ensuring the contents remain intact throughout the packaging’s lifecycle.

Understanding ASTM F392 – Flex Durability of Flexible Barrier Materials

ASTM F392 is a standard specification that outlines the procedure for determining the flex durability of flexible barrier materials. This test method is specifically designed to evaluate the ability of materials like films and coatings to endure repeated bending, twisting, and flexing under stress, simulating real-world conditions during transport and handling.

The test involves subjecting the sample to a series of flexing motions and determining the material’s ability to withstand these stresses without developing holes or cracks. ASTM F392 helps manufacturers and quality control teams assess the reliability and performance of packaging materials, ensuring they meet the standards necessary for effective barrier performance in industries such as food, pharmaceuticals, and medical packaging.

Test Methods in the Gelbo Flex Tester

The Gelbo Flex Tester adheres to the testing procedures outlined in ASTM F392 for flex durability. The process involves mounting a sample measuring 200 mm by 280 mm onto the test mandrels. The sample is then subjected to both twisting and horizontal compression motions, designed to simulate the stresses packaging materials undergo during distribution. Specifically, the system initiates a twisting action that spans 440° within the first 90 mm of the stroke, followed by a horizontal compression of 65 mm.

The test is conducted at a speed of 45 cycles per minute with five pre-programmed test modes:

• Mode A: Full flex for 1 hour (2,700 cycles)
• Mode B: Full flex for 20 minutes (900 cycles)
• Mode C: Full flex for 6 minutes (270 cycles)
• Mode D: Full flex for 20 cycles
• Mode E: Partial flex for 20 cycles

This flexible testing process allows users to simulate various real-world stress scenarios, enabling precise assessments of flex crack resistance.
