A microscopically small leak in a vacuum package is hard to trace. In some cases micro leaks can only be detected by queezing the package 24 to 48 hours after packaging. Then they feel soft. But Oxipack provides a quick alternative solution!How it used to go (and sometimes still does)
To eliminate possible leaks in the vacuum packaging, rows of pallets of packaged products often were stored temporarily one or two days and nights. After which a selection was checked manually to feel if there were any soft bags.
This postponed testing represents a substantial production risks. If the person who verifies finds too many leaky packages the consequence might be that all packaging produced in the meantime has 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 packaging. 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.Features
- The Vacuum Leak Tester has been operating for years now in the coffee industry without any problems.
- For random sample testing.
- Testing of vacuum packaging that contains a slight amount of air or inert gas in between the product, for example ground coffee.
- The measuring chamber and the membrane can be made to precisely fit the packaging that needs to be tested.
- Within thirty seconds a pressure difference of 700 mbar is created. By doing this it is possible to detect leaks right down to less than > 10 µm.
- Simple to operate: a green light indicates if the packaging is sound and a red light indicates a leak.
