ASTM F392

ASTM F392 is a standardized testing method designed to assess the durability and barrier integrity of flexible packaging materials under repeated flexing conditions. This test is essential for industries that rely on high-performance flexible packaging, such as food, pharmaceuticals, and medical devices.

ASTM F392 - Gelbo Flex Test Method

De Gelbo Flex Test is the primary technique used in ASTM F392. It involves repeatedly twisting and compressing the flexible material to simulate real-world mechanical stress. This test helps manufacturers evaluate how well a material maintains its mechanical strength and barrier properties after prolonged flexing.

Test Procedure

  1. Specimen Preparation: The material is cut into 200 mm × 280 mm sheets.
  2. Mounting on the Flex Durability Tester: The sample is attached to two rotating mandrels.
  3. Flexing Process: The specimen undergoes a series of twisting and crushing motions at a rate of 45 cycles per minute.
  4. Evaluation: The material is tested for flex-induced pinholes, barrier degradation, and structural failures.

Testing Conditions and Classifications

The ASTM F392 test is performed under standardized atmospheric conditions (23 ± 2°C and 50 ± 5% relative humidity) and offers different conditioning levels:

  • Condition A: 1 hour (2700 cycles)

  • Condition B: 20 minutes (900 cycles)

  • Condition C: 6 minutes (270 cycles)

  • Condition D: 20 cycles

  • Condition E: 20 cycles (partial flexing)

Conditioning levels A, B, and C assess flex resistance, while D and E evaluate barrier performance under minimal flexing.

This test provides crucial data on:

  • Pinhole formation and flex failure

  • Barrier integrity for moisture and gas transmission

  • Suitability of flexible packaging for high-stress environments

By incorporating ASTM F392 testing, manufacturers can ensure their packaging materials meet industry standards for durability and performance, reducing the risk of product contamination or failure.
