Seal Integrity Tester

Seal Integrity Tester (also known as Negative Pressure Seal Tester) is suitable for testing the sealing integrity of flexible packaging containers such as bags, bottles, tubes, cans, and boxes in industries including food, pharmaceuticals, medical devices, daily chemicals, automotive, electronic components, and stationery. The test effectively compares and evaluates the sealing processes and performance of flexible packaging, providing scientific basis for determining relevant technical specifications. It can also assess the sealing integrity of specimens after drop or pressure resistance tests.

This product employs the negative pressure testing principle. By evacuating the vacuum chamber, an internal-external pressure differential is created on the water-immersed sample. The escape of internal gases is observed to determine the sample's seal integrity. Alternatively, by evacuating the vacuum chamber, an internal-external pressure differential is induced on the sample. The sample's expansion and subsequent shape recovery after vacuum release are observed to assess its seal performance.

This instrument complies with multiple national and international standards: GB/T15171, ASTMD3078, GB/T27728, YBB00112002-2015, YBB00122002-2015, YBB00262002-2015, YBB0005-2015, YBB00092002-2015, YBB00392003-2015, YBB00112002-2015.
