Vacuum Seal Performance Tester Leakage TesterLT-02PComplies with standards such as GB/T 15171 Test Method for Seal Performance of Flexible Packaging and ASTM D3078-02 Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission. Suitable for seal testing of packaging bags, bottles, tubes, cans, boxes, etc., in industries including food, pharmaceuticals, medical devices, daily chemicals, automotive, electronic components, stationery, etc. It can also perform seal performance testing on specimens after drop and pressure resistance tests.

Vacuum Seal Performance Tester Leakage Tester

Testing Principle: By evacuating the vacuum chamber, a pressure difference is created between the inside and outside of the specimen immersed in water. The escape of gas from the specimen is observed to determine its sealing performance. Alternatively, by evacuating the vacuum chamber to create a pressure difference, the expansion of the specimen and its recovery after vacuum release are observed to assess sealing performance.
