Scale-up testing of nanotechnology to enhance barrier properties of packaging materials

Cynthia Riddle (PI), Conestoga Food Research & Innovation Lab

Nfinite Nano developed nanotechnology to enhance barrier properties of packaging materials with a reduced environmental impact compared to traditional options. They sought technical assistance for scaling up their processes, conducting shelf-life and shelf-life extension testing, and optimizing packaging performance. CFRIL supported Nfinite by focusing on scale-up testing. 

Three separate trials were conducted, comparing test films with control films. Testing frequency was determined by product type and occurred bi-weekly. The study involved creating bar-sealed pouches from flat film material to fill with products for comparison against control films without the Nfinite barrier. Additionally, sealing and performance tests were performed using Conestoga College’s pilot plant equipment, including the vertical PFM form-fill-seal equipment and the Multivac tray sealer for lidding film evaluation. Shelf-life testing parameters included texture, oxidation, sensory attributes, moisture content, water activity, and headspace composition. The results provided valuable data on food product performance with and without the Nfinite barrier system.
