A worldwide producer of high-quality foods called Oxipack, they were looking for help with micro-leak problems. They had issues with their container-packed tofu trays filled with water: there were micro leaks during the packaging process. These leaks were not always found in time, resulting in a wet cardboard outer box within a day after packaging. Or worse: broken and dirty packaging sometimes arrived at the supermarkets and restaurants.
The producer wanted to be sure of leak-tight packaging and perform a non-destructive leak detection test immediately after filling and sealing the packaging. Adding a product temperature of over 50 degrees Celsius and a humid environment in the factory, the Oxipack Centre or Expertise gladly accepted the challenge.
Process and result
When the question was received by our leak detection advisors, the Centre of Expertise team immediately started working on different possibilities for testing this packaging. To get a good idea of what the final packaging looks like and how the containers are filled and sealed, Oxipack received sample packaging. During testing, Oxipack saw opportunities to test this type of packaging non-destructively for leaks and airtightness.
A prototype set-up was built to ensure the packaging could be properly tested. The sample container packages were scanned with a 3d scanner and Oxipack created a specific mould in which the product fit perfectly. By making the space around the product as small as possible, it became possible to detect micro leaks as well as larger leaks. After creating the mould with the negative of the product, samples were tested in our smallest leak tester: the Stationary Leak Tester XS.
After excellent testing process and sending over some testing videos, the customer rented the Stationary Leak Tester XS. They experienced in-house during production what it was like to work with a fast, reliable, accurate and non-destructive leak tester. Questions & software updates were quickly arranged together with the Oxipack Support Team to ensure perfect functionality. The added value of the Leak Tester was recognized, and the leak tester was purchased and is now located next to the production line. The Oxipack Centre of Expertise has helped the customer save time and money as well as increase the product quality and reduce waste.
