How the Gelbo Flex Test Ensures Wraps Packaging Durability

Wraps Packaging and the Importance of Durability Testing

In industries like food, pharmaceuticals, and medical devices, wraps packaging plays a critical role in product protection and contamination prevention. The durability of flexible packaging materials—particularly under repeated bending and twisting—is essential to maintain barrier performance and integrity throughout the supply chain. To evaluate this durability, the Gelbo Flex Test is a trusted method, especially when conducted according to the rigorous procedures defined in แอสทาม F392.

Understanding the Gelbo Flex Test, Flex Durability Tester, and ASTM F392

การ Gelbo Flex Test, described in แอสทาม F392, simulates the stresses that flexible materials undergo during handling, transportation, and storage. The test involves a specific mechanical action that combines twisting and compressing motions, placing the material under cyclical strain.

This test is performed using a เครื่องทดสอบความทนทานของความยืดหยุ่น, an instrument specifically designed to mimic real-world mechanical flexing. In ASTM F392, two main test procedures are defined:

• Procedure A: Used to evaluate the potential for particle generation in sterile or clean environments.

• Procedure B: Measures the material’s resistance to pinhole formation after repeated flexing, especially for barrier films.

For wraps packaging, Procedure B is most commonly applied, as pinholes or cracks can compromise product sterility or shelf life.

Why Wraps Packaging Needs the Gelbo Flex Test

Flexible wraps in medical, food, and consumer packaging are often exposed to dynamic movements. Transportation vibration, mechanical loading, and manual handling can cause micro-damage. The Gelbo Flex Test identifies materials prone to barrier failure—a critical concern for manufacturers ensuring product safety and regulatory compliance.

By simulating real-world flexing, this test provides actionable data on the performance of materials. Packaging engineers and quality control teams can use this information to choose more reliable materials, improve process control, or validate new packaging designs.
