Siegwerk has announced the certification of its CIRKIT NATUBAR PR4798 and NATUBAR CT4326 water-based coating for home compostability in compliance with EN 13432, issued by TÜV Austria.
The CIRKIT NATUBAR PR4798 and CIRKIT NATUBAR CT4326 are revolutionary water-based coatings that enhance water and grease resistance in packaging applications. Formulated with non-modified natural polymers, they primarily replace lamination in paper plates. Additionally, these innovative coatings not only allow the final packaging to be in full compliance with the European Packaging and Packaging Waste Directive (PPWR) 94/62/EC and the US regulation «Model Toxics in Packaging Legislation», but are also exempt from the Single-Use Plastics Directive EU 2019/904.
Key Highlights:
- Environmentally Friendly: The coatings contain 100 percent biobased carbon and derive from natural resources.
- Compostability: TÜV Austria has certified these coatings for home composting, ensuring they decompose safely without harming the environment.
- Recyclability: CIRKIT NATUBAR PR4798 and NATUBAR CT4326 have achieved full repulpability, passing tests under the PTS method PTS-RH:021/97 cat II and CEPI Lab Test method v2, with a 100 percent CEPI-scorecard result.
- Product Safety: Formulated using non-modified natural polymers approved for use in food, the coating is safe for direct food contact and has been certified by independent laboratories.
“Achieving TÜV Austria certification for home compostability is a key milestone in our circular economy efforts. It shows we’re meeting future packaging regulations with high performance and environmental responsibility.”
