May 28, 2025

UPM Specialty Papers has come up with an investment plan of more than EUR 10 million to modernize its Tervasaari mill in Valkeakoski, Finland. The upgrade aims to enhance production efficiency and boost capacity for specialty products such as glassine & flexible packaging papers.
The project involves a rebuild of the paper machine’s drying section and improvements to the steam system. The project is expected to be completed by late 2026.
Watch: In Pursuit of Lesser Water Footprint
Currently, the Tervasaari facility produces approximately 300,000 TPA of glassine and packaging papers and employs around 310 staff. Glassine is widely used in industrial applications like labels and double-sided tapes. UPM’s flexible packaging portfolio includes recyclable papers, barrier solutions, and coated one-side (C1S) grades.
UPM Specialty Papers is part of the UPM group, which operates two mills in Finland, and one each in Germany and China, having total production capacity of around 2 million TPA.
