Scholle Packaging’s Materials Science Lab is based in Northlake, IL USA. Our workload is very diverse, but our main function is to work with the Global Packaging Development Group with evaluation of new films, fitments and bag configurations.
The Lab often gets involved with customers when new products are being qualified. For example, we can perform compatibility testing of their product in the exact bag structure they are considering. This expedites the commercialization process by preventing placment of a package in the field and finding out that it doesn’t work due to product migration, seal failures or environmental stress crack failure.
Some products require UN DOT testing. Our lab has drop testing capability, which is one of the tests required to certify a package. We can run this test in order to do initial screening of the package. When certification is required, we can assist the customer with finding labs that can perform the full UN DOT certification testing.
Another area we can help our customers with is transportation testing. We have a vibration table which is very useful when determining if the bag to box fit is correct. If it is not, there will be too much flexing of the bag which causes flex crack holes and leakage in the field.
For a more complete listing of tests we run on a regular basis, please see the chart below.
The Materials Science Lab team is made up of highly-trained and educated people. Collectively, the experience within the group at Scholle totals more than 50+ years. They are a very innovative group and are always coming up with new ways to test development samples, collect data and researching new techniques that can be used in the lab. Together we can solve any problem.

Can you direct me to a method for direct measurement of dissolved oxygen in wine in bag-in-box?
Hi Katarina,
Amy is out on holiday right now, but will respond to your question as soon as possible on this blog page.
If you would like an answer immediately, please feel free to contact us through scholleAP@scholle.com.
Cheers,
Ryan
Katrina, Thank you for your question. We do not have the equipment to measure dissolved oxygen in liquids. What we do, routinely, is measure the oxygen transmission through film and fitments. We also have a small unit which can measure the oxygen in the headspace of a bag filled with a liquid. This would give you an indication of dissolved oxygen in the liquid.
If needed there is equipment you can purchase which will do this for you. Another good resource for you would be the Australia Wine Research Institute (AWRI).
