Circular packaging coatings are helping manufacturers improve the functionality of recyclable packaging without relying on traditional plastic-based solutions. Siegwerk’s CIRKIT NOVASEAL portfolio introduces a range of heat-seal lacquers designed for fiber-based and selected flexible packaging applications. The coatings provide reliable sealing performance, strong hot-tack properties, and efficient processing across different packaging formats while supporting circular packaging goals. By offering multiple formulations optimized for varying temperatures, printing methods, and performance requirements, the portfolio gives converters greater flexibility when designing sustainable packaging systems.
The development reflects growing demand for packaging materials that balance environmental goals with operational efficiency. As brands face increasing pressure to reduce packaging waste and improve recyclability, functional coatings are becoming a critical component of product design. For packaging suppliers and converters, advanced coating technologies create opportunities to support circular economy initiatives, meet evolving regulatory expectations, and deliver performance-driven alternatives that help brands transition toward more sustainable packaging formats.
