Paper-based packaging concept with bio-based coating to meet EU's SUPD rules

UPM Specialty Materials, Michelman, and BOBST have joined forces to develop the two concepts, each combining:

• UPM's fiber-based packaging papers

• Michelman's bio-based coating technologies

• BOBST's application and processing expertise

Both concepts 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," says Mika Uusikartano, senior manager, Product Portfolio Management, UPM Specialty Materials.

The EU's Single-Use Plastics Directive (SUPD) requires that certain packaging categories, including single-use packets and wrappers for food, move away from single-use plastic. The rules are in force, and brands are actively looking for alternatives.

• The concept is designed for dry food applications that fall under the scope of SUPD.

• It is based on UPM Prego with Michelman's bio-based Nuvita Life coatings, applied by BOBST. Both are independently certified as SUPD compliant according to PTS.

• The structure is heat-sealable across a wide sealing window, supporting more stable production with less waste and fewer rejects.

• The concept is recyclable according to Cepi/4evergreen v2.

"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.

The second concept also uses a bio-based coating, extended further on barrier performance.

• It is designed for products that tend to go stale when exposed to oxygen, such as chocolate and single-packed biscuits.

• The concept achieves an oxygen transmission rate (OTR) of 140 cc/m²*day, measured at 23°C and 50% relative humidity, helping safeguard shelf life.

• It is built on UPM Asendo barrier paper, with the same bio-based Nuvita Life coatings from Michelman, applied by BOBST.

UPM, Michelman, and BOBST each contribute a distinct area of expertise: fiber-based packaging papers, bio-based coating chemistry, and application and process technology. The three elements were developed and validated together from the start, rather than combined afterward. UPM ensures the paper structure and performance base, Michelman optimizes the coating chemistry, and BOBST aligns the application parameters and process conditions.

Because the combination is engineered jointly, converters do not need to work out how to combine the paper, coating, and machine settings themselves. The three elements are already designed to function as one system, supporting smoother implementation, stable performance, and efficient 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.
