Packing foods in a modified atmosphere means that the pack integrity has to be well maintained. Any hole or leak in the pack can have an undesirable effect on the quality and safety of the pack contents. The pack seals need to be checked at the same frequency as other quality checks.
The testing could be a simple visual check or possibly a “squeeze” type test next to the sealing machine. Additional testing procedures could be undertaken by off-line laboratory integrity checks using the same packs as used for gas analysis.
There is more specialized non-destructive testing equipment available which is capable of testing for specific gas leakage such as CO
2. This testing can be undertaken in batches off-line or on a continuous basis on-line.
