UPM Specialty Materials and Paramelt have jointly developed a bio-based, paper-based food packaging concept designed to deliver grease resistance and improved end-of-life performance. The solution targets applications including bakery, fast food and convenience packaging, where grease barrier and sealing performance remain critical requirements.
The concept combines UPM Specialty Materials’ barrier base papers with Paramelt’s bio-based heat-seal and barrier coating technology, forming a recyclable paper-based structure suitable for food contact uses. Both components have been individually validated as home compostable under specified conditions.
According to Christiane Laine, Senior Researcher at UPM Innovation, the development focuses on achieving high grease resistance at low coating weights while maintaining runnability on packaging lines. She stated that combining UPM’s barrier paper properties with Paramelt’s coating technology enables performance levels typically associated with fossil-based coatings.
The solution pairs UPM Solide Lucent or UPM Prego papers, engineered for barrier coating applications, with Paramelt Aquavate Bio SB 2383, a water-based coating formulated from biodegradable materials. The combination is designed for a range of food products, including dry and greasy goods in grab-and-go and bakery segments.
The companies indicated that the coating integrates with existing converting and packaging systems, including vertical form fill seal lines, supporting implementation without significant process changes. Low coat weight application also contributes to material efficiency while maintaining required barrier functionality.
Leon Krings, Business Development Manager, Packaging Coatings and Adhesives at Paramelt, said converters and brand owners are seeking technologies that can be integrated into current production environments. He noted that the coating is designed for compatibility with standard coating processes and existing converting lines.
Samples of the packaging concept will be presented at Interpack 2026, with both companies exhibiting their respective materials and technologies at the event. The development reflects ongoing efforts toward fibre-based packaging alternatives across industry.
