Holmen’s Braviken PM52 rebuilt by a shoe blade gap former

Holmen Board and Paper has made a bold entry into the packaging market with a fresh fiber-based lightweight containerboard that sets new standards in sustainability and performance. To support this innovation, Holmen invested in a major rebuild of Paper Machine 52 (PM52) at the Braviken Mill, aiming to boost production capacity and further improve product quality.

The rebuild, executed by ANDRITZ, introduced the patented PrimeForm TW shoe blade gapforming technology, enabling optimal MD/CD strength ratios, superior formation, and efficient dewatering. With this technology unique strength characteristics for containerboard - specifically for SCT improvement - have been achieved . The new PrimeFlow AT headbox enhances jet quality and fiber orientation, while the upgraded press section improves dryness, energy efficiency, and runnability.

With the launch of Holmen Elevate—the lightest kraftliner on the market—Holmen now offers a product range available in 72, 82, and 92 gsm that combines excellent printability, food contact certification, and one of the industry’s lowest CO₂ footprints. This new product line reflects Holmen’s continued commitment to smarter, more sustainable packaging.

Supported by ANDRITZ’s comprehensive engineering and start-up services, the PM52 rebuild has not only delivered strong operational results but also enabled Holmen to redefine lightweight kraftliner. This presentation will share updated performance data, customer feedback, and insights into how Holmen Elevate is shaping the future of fiber-based packaging.
