Viscous Product No Match for New CCI Tech
MicroCurrent HVLD Might Ensure Better Container Closure Integrity for New Product Formulations By Oliver Stauffer, PTI, published in PDA Letter, July/August edition
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 MicroCurrent HVLD can achieve a realiable leak detection limit even all the way down to critical leak sizes.
