MicroCurrent HVLD Might Ensure Better Container Closure Integrity for New Product Formulations

New product types and packaging configurations, such as highly viscous formulations, pose a significant threat to traditional leak-testing methods, challenging current practices for container closure integrity testing (CCI). In light of this, a series of feasibility studies was conducted to challenge traditional leak-testing methods. Using real-world positive control methods conducted to detect defects occurring in the manufacturing process, MicroCurrent High Voltage Leak Detection (HVLD) proved a significantly better test for highly viscous low conductivity products. The studies showed that Micro- Current HVLD can achieve a reliable leak detection limit even all the way down to critical leak sizes.
