As long as plastics are used as packaging materials, barrier films will continue to be an integral part of the application portfolios of packagers under various conditions. The initial focus is usually on an oxygen barrier as well as a barrier against inert gases such as CO2. Although these requirements are still relevant, they are far from sufficient for today's food protection. A modern barrier film must prevent the transfer of many more substances in much smaller amounts to the food such as MOSH (Mineral Oil Saturated Hydrocarbons) and MOAH (Mineral Oil Aromatic Hydrocarbons). In the near future, it will be crucial for every branded goods manufacturer to have a solution. This can be implemented through the use of very thin barrier films. As the presentation shows, EXTENDO® BOPP high barrier films deliver excellent protection, in particular against MOSH and MOAH. The EXTENDO films demonstrably meet the MOAH limit of 0.5 mg/kg in food. The films also meet industry challenges that include avoiding the loss of flavor and preventing odors from entering the packaging. Further, mono-material related systems based on EXTENDO high barrier films offer a far more sustainable, cost-effective solution, as the material can be reused through recycling. The presentation uses modern examples to illustrate how food can be better protected.
