UPM, Michelman and Bobst partner

UPM Specialty Materials, Michelman and Bobst have collaborated to develop two validated paper-based packaging concepts for brands navigating EU packaging rules, including the Single-Use Plastics Directive (SUPD).

By combining fiber-based materials, bio-based coatings and coating line expertise, the three companies have built ready-to-implement structures that deliver strong barrier performance and heat sealability over a wide sealing window.

'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 options faster,' said Mika Uusikartano, senior manager, product portfolio management, UPM Specialty Materials.

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

'There is a growing market demand for SUPD-compliant packaging products. At the same time, barrier performance must remain equivalent to that of existing products, and the proposed materials must be fully compatible with current packaging lines, without requiring major equipment modifications,' said Iulia Mihai, senior scientist at Michelman.
 
From an implementation perspective, the collaboration accounts for process requirements and runnability to support efficient industrial production.

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

The collaboration showcases two concepts. The first concept supports SUPD‑compliant paper packaging for applications such as tea bags, oatmeal and sugar stick‑packs, incorporating bio‑based coatings that provide effective moisture and mineral oil barriers, along with good heat sealability. Packets and wrappers are among the product categories in the 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 enhanced oxygen barrier, such as single-pack cookies and chocolate, while enabling lower coat weights and improved material efficiency.
