UPM Specialty Materials and Paramelt have developed a biobased, paper-based food packaging concept that combines strong grease resistance with improved end-of-life options. The solution targets applications such as bakery, fast food and convenience packaging, where fibre-based alternatives to plastic are in high demand.

High-Performance Barrier With Less Material

The concept combines UPM’s barrier base papers, including UPM Solide Lucent and UPM Prego, with Paramelt’s Aquavate Bio SB 2383. This water-based coating is made entirely from biodegradable components, with 90% derived from biobased sources such as PHA.

The key innovation is its ability to deliver strong grease resistance at very low coating weights. This is difficult to achieve, even with fossil-based coatings. The result is a material-efficient solution that still meets the functional needs of food packaging, including sealing and product protection.

Designed For Circular End-Of-Life

The materials support multiple end-of-life pathways. The combined solution is certified as recyclable according to Cepi/4evergreen standards. At the same time, the individual components are home compostable. This flexibility helps designers respond to different regional waste systems. It also supports broader goals such as reducing plastic use and improving fibre recovery.

Compatible With Existing Production

The solution works with existing packaging and converting lines, including vertical form-fill-seal (VFFS) systems. Manufacturers can adopt it without major changes to their production setup.

Paramelt designed the coating to perform reliably in standard industrial processes. This makes the transition to biobased materials more practical and scalable.

Relevance For Designers

For packaging and product designers, this development shows the growing potential of fibre-based materials with advanced coatings. These materials can now match the performance of plastics while offering better environmental outcomes. As sustainability requirements continue to evolve, such innovations enable designers to create packaging that is both functional and circular by design.
