System detects leaks in modified atmosphere packaging

Engineered for meat, poultry, seafood and prepared foods packaged with tray sealers or thermoforming machines, the Linde MAPAX LD inline leak-detection system achieves 100 percent sampling at speeds up to 120 packages/min. After a small volume of hydrogen is added as an indicator to the modified atmosphere mixture at the package sealing stage, the sealed packages travel into the leak-detection unit. If the system’s sensor detects a package leak, a visual alarm signals so the defective item can be removed from the production line.
