Sustainable barrier coatings: Reducing waste in food packaging material

With increasing demand for more sustainable packaging, brands and manufacturers are seeking to reduce the amount of material used for food packaging and lessen the environmental impact. Yet, especially in food packaging applications, there is a need to preserve the food by protecting it against elements such as light or oxygen that may degrade it. Traditionally film layers such as EVOH have been utilised to provide this barrier. However, these films may negatively impact the recyclability of the packaging. To solve this issue, coatings specialists Siegwerk and Henkel have partnered to develop a sustainable oxygen barrier coating for food packaging. We learn more about the project.
