Oxipack leak detection BV

With our new (100%) fully automatic in-line leak detection unit, it is now possible to test up to 120 packages per minute for leakage and airtightness. Due to the modular construction, you can choose between speeds of 20, 40, 60, 80, 100 or 120 packages per minute. We guarantee accuracy down to 10 microns (one hundredth of a millimeter). Due to its compact size and construction, The Rotary can be placed in both new packaging lines and existing packaging lines.

Our principle, of the Stationary Leak Tester, is now implemented in a fully automatic in-line solution. The Rotary can measure, just like the Stationary Leak Tester, down to 10 microns. Due to its compact size, The Rotary can be placed in new production lines as well as existing production lines.

The Stationary Leak Tester has been specially developed for off-line sample testing of flexible packages. Using this equipment, you can manually test packages that have small amounts of air in it or packages that contain inert gas. For example, modified atmosphere packages (MAP) with a protective atmosphere. Examples of MAP-packages are: sachets of grated cheese, nuts, part-cooked bread, coffee pods or pet food.

By carrying out systematic tests for leaks, you minimise the percentage of leaking packages, prevent complaints about poorly sealed packages and reduce food waste.

How do you test airtight rigid packages for leaks? Packages with a solid form cannot be tested with the Stationary Leak Tester, the membranes would not fit properly. For this type of rigid packages that contain air or an inert gas, we have developed a different kind of leak tester. This leak tester creates as little space as possible between the measure chamber and the package.

With our Can Leak Test solution we are able to non-destructively test cans with an accuracy down to 10 microns. The solution can be used as a sample tester, the packages should be placed manually in the leak tester and the tester needs to be operated manually. This Oxipack solution, can perform non-destructive leak tests that are more accurate than the classic water bath test. The operator needs to, manually, place the cans into the machine in their normal position.

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.
