In-line testing of modified atmosphere packaging


Witt-Gasetechnik has a reliable inline CO2 leak detector (Leak-Master® MAPMAX) that is capable of operating up to 15 cycles per minute. The equipment is designed to operate in conjunction with thermoforming and tray-sealing packaging equipment.

All data is stored and can be made available for further evaluation or as a quality log.

This is a significant improvement over previous methods where random testing was performed, either by hand in water baths or in complicated procedures using tracer gasses. Carbon Dioxide is a natural choice for a detector gas as it is safe to handle and it is present as it is generated by many foodstuffs.
