UPM Specialty Materials, Michelman, and Bobst have joined forces to develop two validated paper-based packaging concepts for brands navigating the EU packaging rules, such as 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 solutions faster,” says Mika Uusikartano, senior manager, product portfolio management, UPM Specialty Materials.
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.
“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,” says Iulia Mihai, senior scientist at Michelman.
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,” says Luca Nespolo, competence center manager, Bobst.
The collaboration showcases two solution 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 impart good 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 improved oxygen barrier level, such as single pack cookies and chocolate, while enabling lower coat weights and improved material efficiency.
Sample structures of both solutions were shown at Interpack 2026 at UPM Specialty Materials Michelman stands.
IndiFoodBev — authentic, impactful and influential
An English-language food and beverage processing and packaging industry B2B platform in print and web, IndiFoodBev is in its third year of publication. It is said that the Indian food and beverage industries represent approximately US$ 900 billion in revenues which implies more than 20% of the country’s GDP. Eliminating the wastage on the farmside can help to deliver more protein to a higher number of the population apart from generating sizable exports. The savings in soil, seeds, water, fertilizer, energy and ultimately food and nutrition could be the most immense contribution that country is poised to make to the moderation of climate change.
