UPM, Michelman, and BOBST develop bio-based coatings for paper packaging

Last update on May 12, 2026

Formulators and packaging material developers evaluating SUPD-compliant structures can now assess two validated paper-based packaging concepts developed through a collaboration between UPM Specialty Materials, Michelman, and BOBST. The concepts are designed for brands navigating EU packaging rules, including the Single-Use Plastics Directive (SUPD), and combine fiber-based materials, bio-based coatings, and coating line expertise to deliver barrier performance and heat sealability over a wide sealing window.

Meeting growing market demand for SUPD-compliant solutions

The concepts combine UPM's packaging papers with Michelman's bio-based coating solutions and BOBST application know-how to deliver functional performance while supporting recyclability and, where relevant, compostability across selected applications.


"Fulfilling strict expectations demands scalable solutions. Our base papers are developed to support co-creation and reduce unnecessary complexity. Combining them with the right chemistry enables partners to arrive at fit-for-purpose packaging solutions faster," said Mika Uusikartano, senior manager, Product Portfolio Management, UPM Specialty Materials.


"There is a growing market demand for SUPD-compliant packaging solutions. At the same time, barrier performance must remain equivalent to existing market solutions, and proposed materials must be fully compatible with current packaging lines, without the need for major equipment modifications," said Iulia Mihai, senior scientist, Michelman.

Imparts heat sealability, moisture and mineral oil barriers

From an implementation perspective, the collaboration takes into account process requirements and runnability to support efficient industrial production.


"When materials and application parameters are developed together, packaging converters can implement new solutions more easily while achieving stable performance and production efficiency," said Luca Nespolo, competence center manager, BOBST.


The collaboration covers two solution concepts. The first supports SUPD-compliant paper packaging for applications such as tea bags, oatmeal, and sugar stick-packs, incorporating bio-based coatings that impart moisture and mineral oil barriers along with heat sealability. Packets and wrappers are among the product categories in scope of the EU's SUPD, which aims to reduce the environmental impact of certain plastic products that are used once and discarded.


The second concept is designed for applications requiring an improved oxygen barrier level, such as singlepack cookies and chocolate, while enabling lower coat weights and improved material efficiency.

Sample structures of both concepts were displayed at Interpack 2026 at UPM Specialty Materials' stand in Hall 8A, Stand F29 and Michelman's stand in Hall 8A, Stand B25.


The partners also shared insights in a joint presentation, 'Simplifying Adoption of Sustainable Packaging for Brands', on May 11, on the SPOTLIGHT Forum stage in Entrance North B.
