Siegwerk, a global provider of printing inks and coatings, has announced the introduction of its new heat-seal lacquer portfolio, branded as Cirkit Novaseal. Available to the market starting in May 2026, this product line targets fiber-based and selected flexible packaging applications. For industry executives overseeing rigorous quality controls in sensitive sectors, where reliable structural integrity is paramount, the release supports the broader transition toward high-performance, recyclable packaging designs.
The Cirkit Novaseal range unifies various heat-sealing technologies under a single product identity. According to Siegwerk, these specialized formulations were developed partially through the company’s strategic acquisition of Allinova. This consolidated heat-seal lacquer portfolio is engineered to provide consistent sealing, reliable hot-tack performance, and durable bond strength across a variety of demanding flexible packaging environments.
Optimized for both flexographic and gravure printing processes, the Cirkit Novaseal formulations accommodate a wide spectrum of sealing temperature requirements. The technical parameters of the heat-seal lacquer portfolio are critical for high-speed production environments where structural reliability cannot be compromised. Key operational profiles include:
- Low seal initiation temperatures for streamlined operations.
- High hot-tack performance tailored for rapid packaging lines.
- Exceptional bond strength maintained even at low coating weights.
These variants ensure that flexible packaging maintains functional safety while aligning with modern circularity principles. As a core component of the broader Cirkit brand, the solutions focus on maintaining rigorous performance standards while enabling structural updates to recyclable packaging formats.
Gilles Le Moigne, head of circular economy coatings at Siegwerk, noted that the unified product brand simplifies the navigation of performance requirements for converters and brands. “Cirkit Novaseal is a key milestone in strengthening our coatings offering for sustainable packaging,” stated Le Moigne. He emphasized that combining their expertise in heat-sealing technologies under one structured umbrella helps customers meet circular economy targets with enhanced transparency.
Siegwerk confirmed that the current Cirkit Novaseal lineup is fully accessible to manufacturers, supported by the organization’s dedicated technical service and application teams to facilitate smooth operational integration.
