Designed for dry-filled pre-made and FFS pouches, stick packs, sachets and flexible packaging, the PTI VeriPac 425/LP automatic online inspection system includes vacuum decay leak testing technology that provides non-destructive package testing and reliable leak detection as small as 10 microns. Using a conveyor infeed, pouches are automatically fed into the test chamber. After the test cycle is completed, defective packages are rejected, and good packages are placed back into the production line. The system provides a qualitative result (PASS or FAIL) as well as quantitative data that correlates to leak rate and leak size.
