Substrate provider UPM Specialty Papers says it will invest more than US$11 million in the modernization of its UPM Tervasaari mill in Valkeakoski, Finland. The investment will allow UPM Specialty Papers to boost capacity and improve production stability in its highly specialized products, such as glassines and flexible-packaging paper substrates.

“UPM Specialty Papers has over 40 years of experience producing highly demanding specialty papers. This investment underscores our commitment to serving customers in the label, tape and industrial value chains as well as packaging,” says Tomi Lonka, senior vp-Global Specialty Papers, UPM Specialty Papers.

The modernization project includes the paper-machine drying section rebuild and related steam system upgrade. The project is expected to be completed at the end of 2026. In recent years UPM has also invested approximately US$22 million in boosting the energy efficiency of UPM Tervasaari mill. For example, in 2023, a new electric boiler was installed.

UPM Specialty Papers offers a comprehensive portfolio of high-quality glassine papers and packaging papers, typically used in labels, double-sided tapes and other industrial end-uses. For flexible packaging, UPM offers fibre-based, recyclable papers, including barrier, barrier base, and C1S (coated one side) packaging papers.
