Circular Economy Coatings
Rethinking packaging with functional coating technologies for protection, performance and circularity.
Our Circular Economy Coatings are designed to help packaging move towards greater recyclability, reduced plastic use and improved material efficiency while maintaining the protection and performance required for modern packaging applications.
The portfolio combines barrier coatings, barrier inks, heat sealing lacquers, protection solutions and functional additives to support fiber-based, flexible and mono-material packaging concepts. Each solution is developed to address specific functional needs, from product protection and heat resistance to sealing performance, process stability and surface optimization.
By reducing material complexity and enabling more circular packaging structures, our coatings help converters and brand owners improve packaging sustainability without compromising runnability, compliance, shelf life or market performance.
