Modified Atmosphere Packages are critically dependent on the quality of the seal to ensure the retention of the protective environment.
The adjustment of heat seal temperatures, wrinkles in the film components, contamination in the seal area and variations in the pack materials can all contribute to leaking seals.
A simple, quick, reliable and non-destructive test is essential to ensure that the sealing system is optimised, and that expected shelf lives are achieved.
Many of the systems recommended for testing MAP packages are based on the detection of the special gas mixture escaping from the package.
However, it is often much quicker and less expensive to measure the total gas leakage rate as a means for identifying faulty packs.
The optimum configuration for a test system is highly dependent on the pack volume and shape, as well as the test rate required. Depending on the product and package design, 100% on-line or sample testing may be required to achieve acceptable quality levels.
Technical & Scientific can offer a range of locally developed test systems specifically designed for particular applications ranging from flexible flow wrap or form fill & seal bags to rigid cups and trays as singles or clusters.
