Linde LLC introduced the high-speed, inline MAPAX LD (leak detection) system, ideal for meat, poultry, seafood and prepared foods packaged with tray sealers or thermoforming machines. The MAPAX LD tests packages inline and can achieve 100% sampling at speeds up to 120 packages per minute. It works by adding a small volume of hydrogen as an indicator to the modified atmosphere mixture at the package sealing stage. The MAPAX LD sensor detects for the gas after the sealed packages travel into the leak detection unit. Because testing is inline, if a package leak exists due to a pinhole, tear or defect in the seal, a visual alarm signals, so issues can be immediately resolved or investigated. A defective item can be removed from the production line with minimal interruption to the process flow. MAPAX LD also identifies faulty settings on a machine if, for example, several leaks are found consecutively.
