UPM and Felix Schoeller are working on a new generation of fiber-based flexible food packaging. The two manufacturers presented this concept, designed for chocolate and cereal bars in particular, combining paper and barrier properties.
This recyclable flexible packaging (CEPI version 3 and 4evergreen version 2.0) is based on the Finnish group's UPM Solide Lucent paper. German papermaker Felix Schoeller applies functional layers that can be adjusted according to need.
"We always start from our customers' needs. Instead of relying on fixed technologies or standard barrier levels, we design customizable coating solutions that offer the required protection against oxygen, moisture, grease, or for waterproofing and mechanical performance." explains Andreas Bergmeier, head of innovation and technical packaging sales at Felix Schoeller.
This project was launched in response to increased regulatory pressure in Europe. The forthcoming PPWR regulation on packaging and packaging waste requires an increase in recyclability.
According to the two manufacturers, UPM Solide Lucent paper has a dense, smooth surface, enabling coating quantities to be kept to a minimum while retaining the mechanical properties required for high-speed packaging lines. Several grammages will be offered to suit different applications. The two partners also point out that the structure facilitates converting operations, a key point for integration into existing lines.
UPM and Felix Schoeller's solution will be on display at UPM Specialty Materials' stand F29, Hall 8A, at Interpack 2026 in Düsseldorf, Germany, May 7-13.
