The installation of a new headbox on paper machine 6 at Gruvön mill will enhance strength, quality consistency, and sustainability of Billerud Flute®.
Dec. 10, 2025 - Billerud is making a targeted investment at its Gruvön mill in Sweden that will enhance strength, quality consistency, and sustainability for the company's flagship product, Billerud Flute®
The investment involves the installation of a new headbox on one of the mill's paper machines.
"The new headbox will be installed on Gruvön paper machine 6 (PM6)," company spokesman Johan Wredberg told PaperAge.
"The production capacity of the machine is about 275 000 tonnes of fluting annually," Wredberg added.
According to Billerud, the upgrade will improve fiber orientation, sheet uniformity and enable higher strength properties for Billerud Flute — all key benefits for converters and brand owners in demanding logistics and climate conditions.
Johan Wallin, Acting VP Business area Paperboard at Billerud, stated, "Billerud Flute is already recognized for its world-class performance and reliability. This investment ensures we continue to lead the industry in fresh fiber fluting, delivering measurable performance and sustainability improvements for our customers.
"This is another step in our long-term strategy to deliver high-performing, renewable packaging materials that enable lower total cost of ownership and reduce environmental impact," he concluded.
The rebuild is planned for April 2026.
Launch of the next level Billerud Flute is scheduled for second half of 2026.
The Gruvön mill in Sweden produces fluting, liners, and liquid packaging board, and has the capacity to produce 870,000 tonnes per year. The mill also houses a development center with expertise in packaging optimization.
Billerud is a global leader in paper and packaging materials made from cellulose fibers. Based in Solna, Sweden, the company serves customers in more than 100 countries through nine production units in Sweden, USA, and Finland and has around 5,800 employees in 19 countries.
