Gelbo Test Method Equipment For High Barrier Flexible Packaging Material By ASTM F392

Background

Gelbo Test Method Equipment plays a crucial role in evaluating the flex durability of flexible barrier materials. Flex durability, or Gelboflex resistance, refers to a material's ability to endure repetitive strain without failure. For industries utilizing flexible packaging, strong flex crack resistance is essential to minimize the risk of package perforation during shipping and handling. Maintaining package integrity ensures the contents remain protected and uncontaminated throughout the distribution process.

The GFT-02 Flex Durability Tester, commonly referred to as Gelbo Test Method Equipment, is specifically designed to assess how materials such as films, laminates, and coated films withstand repeated bending and twisting. By simulating real-world strain conditions, this equipment identifies potential weak points in packaging materials, helping manufacturers enhance their product durability standards.

Application

The Gelbo Test Method Equipment is widely used to test the flex durability of materials like plastic films, composites, laminates, and other flexible barrier materials. The equipment measures flex crack resistance by detecting pinholes or failures that may develop in the sample material after undergoing repetitive flexing. This ensures the packaging remains robust and intact, reducing the likelihood of leaks or contamination during transportation and storage.

Industries such as food, pharmaceuticals, textiles, adhesives, and packaging rely on flexible barrier materials to maintain product safety and quality. The GFT-02 Flex Durability Tester ensures these industries can confidently use materials that meet stringent quality standards.

Conformance to ASTM Standards

The Gelbo Test Method Equipment conforms to ASTM F392, which specifies the standard test method for determining the flex durability of flexible barrier materials. Compliance with ASTM F392 provides users with assurance that the testing procedures and outcomes meet globally recognized standards, offering a reliable measure of a material's durability.

Sampling and Motion Mechanics

The Gelbo Test Method Equipment operates by securing a sample measuring 200 by 280 mm onto the mandrels of the tester. The test subject is then exposed to a series of twisting and horizontal compressions, effectively mimicking the mechanical stresses a material may encounter during real-life handling and distribution. The equipment initiates a twisting motion of 440 degrees within the first 90 mm of the stroke, combined with a linear horizontal movement of 65 mm. The testing occurs at a rate of 45 cycles per minute, allowing for comprehensive stress evaluation.

The GFT-02 provides five preset 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

These different modes accommodate a wide range of testing scenarios, enabling users to assess materials under various simulated conditions.
