Siegwerk said Cirkit Novaseal brings together its circular economy approach and its experience in heat sealing, drawing on experience and technologies obtained through the Allinova acquisition within a single product line.<\/p>\n

The heat-seal lacquers are made for sealing consistency, hot-tack results and bond strength across different packaging uses.<\/p>\n

The range includes products with varying characteristics and performance profiles, including options suited to gravure and flexographic printing and to different sealing temperature needs.<\/p>\n

According to the company, the line includes versions with low seal initiation temperatures for processing efficiency, strong hot tack for high-speed packaging operations, and bond strength at low coating weights to support converting methods such as flexo and gravure.<\/p>\n

The structure of the range is meant to help converters choose lacquer products according to application method, performance requirements and end-use needs.<\/p>\n

Within Siegwerk\u2019s Cirkit brand, the Novaseal line has been developed with circularity in mind.<\/p>\n

The range is aimed at paper-based packaging and selected flexible applications, combining functional use with packaging designs intended to support recyclability.<\/p>\n

Cirkit Novaseal products are already on the market and are backed by Siegwerk\u2019s technical service and application support.<\/p>\n

Siegwerk circular economy coatings head Gilles Le Moigne said: \u201cCirkit Novaseal is a key milestone in strengthening our coatings offering for sustainable packaging.<\/p>\n

\u201cBy unifying our heat\u2011sealing expertise under one strong product brand, we make it easier for customers to navigate performance requirements while aligning with circular economy goals.\u201d<\/p>\n

In March, Siegwerk received RecyClass Technology Approval<\/a> for its nitrocellulose-free flexo ink system, UR 62, and gravure ink system, UR 74.<\/p>\n
