UPM × Paramelt: introducing a bio-based food packaging concept with strong grease protection

A fibre‑based solution designed for demanding end‑uses 

Brand owners and converters are increasingly seeking fibre‑based alternatives for food packaging, especially for greasy, on‑the‑go foods. These applications typically rely on fossil‑based plastic coatings or laminates to achieve effective grease barriers and seal integrity. 

Through co‑creation, UPM and Paramelt set out to develop a paper‑based food packaging concept that delivers the performance required for demanding applications, while significantly improving end‑of‑life performance. 

Bio-based by design: advanced barrier papers meet bio‑based coating technology 

The co‑created concept pairs UPM Solide™ Lucent or UPM Prego™ barrier base papers, engineered specifically as substrates for barrier coatings, with Paramelt Aquavate™ Bio SB 2383, a water-based coating formulated exclusively from biodegradable components. 

The result is a high‑performance, fibre‑based packaging solution that: 

• Strong grease resistance at low coating weights
• Reliable heat‑sealing suitable for food packaging applications
• Compatibility with existing converting and packaging equipment, including vertical form‑fill‑seal (VFFS) lines
• A recyclable, paper‑based structure with improved end‑of‑life performance

The paper‑based structure is designed to fit existing paper recycling streams, and the individual components have been validated as home compostable. 

Co‑creation driving sustainable innovation 

The UPM × Paramelt collaboration demonstrates how co‑creation helps accelerate the development of fibre‑based packaging solutions that balance performance, scalability and sustainability. 

By combining expertise in advanced barrier papers and bio‑based coating technologies, the partners have created a food packaging concept that supports the transition toward more sustainable packaging.
