Stora Enso Starts-up Rebuilt Consumer Board Machine at Oulu Mill in Finland

The newly converted paper machine at Stora Enso's Oulu mill can now produce folding box board (FBB) and coated unbleached kraft (CUK), with an annual capacity of 750,000 tonnes.

March 19, 2025 - Stora Enso's new consumer packaging board line at its Oulu pulp and paper mill in Finland has started production ramp-up. The first customer deliveries are expected in the second quarter of 2025.

In October of 2022, Stora Enso announced its decision to convert the remaining idled paper machine (PM 6) at the Oulu site into a highly flexible consumer packaging board line for folding box board (FBB) and coated unbleached kraft (CUK), with an annual capacity of 750,000 tonnes. The project is being completed according to the original timeline and budget of approximately EUR 1 billion.

Voith performed the full-line paper machine conversion for Stora Enso.

The new packaging board line is expected to reach EBITDA breakeven by the year-end 2025 and full capacity during 2027, at which point annual sales are anticipated to be approximately EUR 800 million.

Renewable packaging is Stora Enso's largest growth segment. The investment supports the Group's strategy by further strengthening the customer offering in the growing FBB and CUK segments. The targeted segments are frozen, chilled and dry food, as well as beverage multi-packaging, primarily for customers in Europe and North America.

"The new line will be the most modern and cost-efficient in Europe," stated Hans Sohlström, President and CEO of Stora Enso. "Through this investment, our Oulu unit will become Stora Enso's largest production facility, an integrated mega-site, focusing on future packaging board grades and featuring a flexible production setup. This will strengthen profitability and competitiveness for our consumer board and containerboard offerings. It will also enable us to optimise production at our other sites to unlock further profitable growth, for example in liquid packaging board at our Skoghall site in Sweden."

Following this investment and the earlier conversion completed in 2021, the Oulu site will produce unbleached pulp, kraftliner, and consumer board in both reels and sheets.

The Oulu mill employs a total of approximately 650 people.

Wood consumption at the Oulu site will increase by approximately one million cubic metres to approximately 3.5 million cubic metres per year. The site will use local wood supply in production as well as pulp from Stora Enso's Enocell site in Finland and Veracel site in Brazil.

In addition, the announced acquisition of the Junnikkala sawmills would further strengthen cost-efficient, long-term supply of raw materials such as wood chips, pulpwood, and biomass.

Stora Enso is the leading provider of renewable products in packaging, biomaterials, and wooden construction, and one of the largest private forest owners in the world. Stora Enso has approximately 19,000 employees. Sales in 2024 were EUR 9 billion.
