Siegwerk, a leading global provider of printing inks and coatings for food and beverage packaging applications and labels, proudly announces the certification of its CIRKIT NATUBAR PR4798 and NATUBAR CT4326 water-based coatings 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 formulated with non-modified natural polymers. These innovative products enhance water and grease resistance in food and beverage packaging applications, primarily used to replace lamination in paper plates. Importantly, these coatings ensure that final packaging complies fully with the European Packaging and Packaging Waste Directive (PPWR) 94/62/EC and the US regulation ‘Model Toxics in Packaging Legislation.’ Additionally, they are exempt from the Single-Use Plastics Directive EU 2019/904.
**Key Highlights:**
• **Environmentally Friendly:** The coatings are 100% biobased carbon, sourced from natural resources.
• **Compostability:** Certified for home composting, these coatings can decompose without harming the environment.
• **Recyclability:** CIRKIT NATUBAR PR4798 and NATUBAR CT4326 are fully repulpable, having been tested according to the PTS method PTS-RH:021/97 cat II and CEPI Lab Test method v2. They achieved a CEPI-scorecard result of 100%.
• **Product Safety:** Formulated using non-modified natural polymers that are approved for direct food contact, these coatings have been certified by independent laboratories for safety.
“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,” says Gilles LeMoigne, Business Unit Head Circular Economy Coatings.
