Testing vacuum packed food for leaks
A microscopically small leak in a vacuum package is hard to trace. In some cases, micro leaks can only be detected by squeezing the package 24 to 48 hours after being packed. If the package is leak, it will feel soft. However, Oxipack provides a quick alternative solution!
How it used to go (and sometimes still does):
To eliminate possible leaks in the vacuum packages, packed products often were stored temporarily one or two days and nights. After which, a selection was checked, manually, by feeling if there were any soft bags.
This 'postponed testing' represents substantial production risks. If the person who verifies, finds too many leaky packages the consequence might be that all packages produced in the meantime have to be rejected. In many cases, these will then have to be cut open and repacked again if possible, or be discarded as waste.
Immediately after sealing:
At the time we developed our leak detection method for the famous Dutch coffee roaster Douwe Egberts. This invention made it possible to determine whether a package leaks or not – shortly after the vacuuming and sealing. Which is long before anyone might observe this by squeezing the packages.
This method is further developed by Oxipack, resulting in the very reliably operating Vacuum Leak Tester. Now, you can test samples for leaks regularly with this device, right after packing. As a result, the temporary storage can be greatly reduced or even become superfluous. This contributes to a tight Lean Six Sigma supply chain management.
