UPM Specialty Materials and Paramelt have jointly developed a bio-based and paper-based food packaging concept designed for bakery, fast food and convenience applications. The solution combines UPM's advanced barrier base papers with Paramelt's bio-based heat-seal and barrier technology to deliver grease protection and improved end-of-life performance. The components have been individually validated as home compostable, according to UPM.
The concept pairs UPM Solide Lucent or UPM Prego papers, engineered as a base for barrier coatings, with Paramelt Aquavate Bio SB 2383, a water-based coating formulated exclusively from biodegradable components. The collaboration demonstrates efficient integration on existing packaging lines, including vertical form fill seal operations, with the coating enabling low coat weights while maintaining reliable performance.
Christiane Laine, Senior Researcher at UPM Innovation, stated that achieving the level of grease resistance at such low coat weights is highly challenging even with fossil-based coatings.
Leon Krings, Business Development Manager for Packaging Coatings & Adhesives at Paramelt, noted that the bio-based coating is designed for reliable performance on standard coating processes and existing converting lines, enabling a practical shift toward recyclable and home compostable fiber-based solutions.
