In an article published on February 8, 2016 by the news provider Food Production Daily, journalist Jenny Eagle reports on a new bio-based barrier film developed by the Technical Research Centre of Finland (VTT). VTT’s Surface treatment concept (SutCo) pilot coating line provides a 2-layer film that can be used as a ‘bag-in-box’ liner for dry foods such as breakfast cereals. The barrier bags are made from bio-based high-density polyethylene (bio-HPDE) film coated with (2,2,6,6-tetramethylpiperidin-1-yl)oxyl cellulose nanofibrils (TEMPO-CNF). According to VTT, their 2-layer film can decrease the amount of mineral oil migration from packaging into food by 90% as compared to non-coated bio-HDPE or other commercial cereal bag films. VTT’s technology is patent pending and they are looking for industrial partners to commercialize their innovation.
