Siegwerk to Present New Functional Paper Coatings at Specialty Papers Europe 2024

Siegwerk announced its participation in Specialty Papers Europe 2024, a conference for the specialty paper and packaging industry, taking place on Sept. 3-4, 2024, in Vienna, Austria.

Siegwerk experts will be available for discussions at the conference and provide insights into the company’s ink and functional coating portfolio that supports the realization of high-performing, circular paper packaging, including some new barrier and sealing coatings specially designed for paper mills.

“More and more brand owners and manufacturers are turning to renewable and recyclable materials to sustainably pack their products, especially resulting in a growing demand for paper packaging,” says Oliver Waddington, head of business development, circular economy coatings at Siegwerk.

“This comes with the challenge of functionalizing fiber-based materials like paper in such a way that the barrier and process requirements of the respective packaging application are met, while ensuring smooth disposal in the wastepaper recycling process,” added Waddington.

Here, functional coatings can play a key role in achieving the required functionalities that are crucial for the performance and durability of the paper packaging without compromising its natural recyclability, a topic the company expert will also address in more detail in his presentation “Functionalizing Paper for Packaging Applications” on day two of the conference.

From barrier coatings through heat seal and protection coatings to delamination and deinking primers, Siegwerk offers a wide range of water-based and solvent-based functional coatings under its CIRKIT product portfolio today, covering different applications, substrates, coating processes and performances.

At Specialty Papers Europe 2024, the company will present four new water-based CIRKIT products specially designed for use in paper mills.

“Applicable by using standard coating processes, the new functional coatings support the efficient production of recyclable specialty papers with various barrier and sealing functions,” explains Waddington. “Therefore, they enable the realization of innovative paper packaging solutions without the need for plastic-laminates commonly used to gain similar functionalities.”

As part of its new coating applications for paper mills, Siegwerk now introduces CIRKIT BAR SEAL CT 1420and CIRKIT BAR SEAL CT 1422, two multi-functional coating systems of which the latter is not only suitable for paper and board but also for metallized papers. They both combine good barrier functionality against liquids and water vapor with excellent heat-seal capabilities and thus enable innovative paper solutions without the need for separate plastic lamination.

With CIRKIT BAR CT 2513 the company offers another excellent barrier coating for paper mills that features both effective barrier properties against grease and oil as well as high heat resistance. And with CIRKIT NATUBAR CT 4326, there is now also a paper coating solution available that is based on natural raw materials and not only offers a good barrier functionality against liquids, grease and oil but also complies with the Single-Use Plastics Directive (SUPD).
