Siegwerk announces the launch of Cirkit Novaseal, a new dedicated portfolio of heat seal lacquers (HSL) within its Cirkit coatings brand. The new product family delivers reliable and consistent sealing performance for fibre-based and selected flexible packaging solutions, supporting brand owners and converters in the transition to more sustainable packaging.
It brings together its circular economy strategy and proven heat-sealing expertise, integrating the know-how and technologies gained through the Allinova acquisition into one coherent and clearly positioned product family.
Its heat-sealing lacquers are designed to enable consistent sealing, good hot-tack performance and robust bond strength across a wide range of packaging applications. The portfolio covers multiple product characteristics and performance profiles, offering solutions optimised for gravure and flexographic printing, as well as different sealing temperature requirements.
The product range includes variants with: Low seal initiation temperatures for efficient processing; Excellent hot-tack performance for high-speed packaging lines; High bond strength at low coating weights, supporting converting processes such as flexo or gravure. This structured portfolio approach allows converters to select the right lacquer based on application method, performance needs and end-use requirements.
As part of its Cirkit brand, Novaseal solutions are developed with circularity in mind. The portfolio is tailored for paper-based packaging and selected flexible applications, enabling functional performance while supporting recyclability-driven packaging designs.
Gilles Le Moigne, head of circular economy coatings at Siegwerk, said, “Cirkit Novaseal is a key milestone in strengthening our coatings offering for sustainable packaging. By unifying our heat-sealing expertise under one strong product brand, we make it easier for customers to navigate performance requirements while aligning with circular economy goals.”
