ASTM F1140

Test Materials: ASTM F1140 specifies the use of flexible packaging materials, including pouches, bags, and seals. The materials should reflect actual products intended for use, ensuring that the test results are relevant and applicable to real-world applications.
Test Process: The testing process involves subjecting the flexible packaging to a vacuum to determine the integrity of the seals. The package is placed in a vacuum chamber, and the pressure changes are monitored to assess any leaks, simulating conditions that the packaging may encounter during storage and transportation.
Test Result Interpretation: Results are interpreted by evaluating the pressure levels maintained within the vacuum chamber. A stable pressure indicates good seal integrity, while significant pressure drops suggest potential leaks. These findings are essential for ensuring product safety and quality in packaging applications.
