ASTM F1140

Application Materials

ASTM F1140 is applied to flexible packaging materials used in various industries, including food, medical, pharmaceutical, and consumer goods. These materials are tested to determine their burst strength and integrity.

Test Process

  1. Preparation: Select the appropriate packaging material sample.
  2. Conditioning: Condition the sample to the required temperature and humidity levels.
  3. Setup: Place the sample in the burst tester. Seal the sample edges securely.
  4. Pressurization: Gradually apply pressure to the sample until it bursts.
  5. Recording: Record the pressure at which the sample bursts.

Test Result Interpretation

The burst strength is the pressure at which the sample fails. Results are typically expressed in psi (pounds per square inch) or kPa (kilopascals). Higher burst strength indicates better durability and integrity of the packaging material.

Test Significance

The burst strength test helps in evaluating the ability of packaging materials to withstand internal pressures during handling, storage, and transportation. It ensures that the packaging will protect the product effectively and maintain its integrity under stress.
