  • Leak testing of modifi ed atmosphere packages

    In leak testing, a distinction should generally be made between random sampling and integrated testing. Testing random samples to identify leaks is a low-cost method, but limited to individual packages instead of an entire batch. If a significant number of units are sampled, reasonably reliable conclusions can be drawn about the status of the
