Valmet will modernize a paper machine (PM10) at the Kruger paper mill in Trois-Rivières, Que., as part of a project to convert the newsprint machine to produce containerboard.
PM10 will be rebuilt using advanced containerboard manufacturing and automation technology to produce 360,000 tonnes per year of 100 per cent recycled lightweight and high-strength linerboard. The rebuilt production line will start up in 2017.
The value of the order has not been disclosed. Valmet notes that the value of paper machine rebuilds depends on the scope of the delivery, and this kind of rebuild is typically valued around EUR 30 million.
“Kruger selected Valmet based on its innovative technology and track record of successful rebuilds, as well as their knowledge of North American recycled linerboard requirements,” explains Christian Lemay, project manager, Kruger Packaging L.P.
The modernization project is expected to generate significant growth opportunities for Kruger.
PM 10 is approximately 8.4 metres wide. It will be fully modernized from headbox to winder to produce linerboard with industry-leading high strength-to-basis weight properties, and with sheet formation and surface characteristics suitable for high-quality graphic printing for corrugated box plants.
In addition to the machinery improvements, the delivery will include a Valmet DNA automation system with remote servicing capabilities for machine and process control as well as MD/CD controls. Valmet will deliver also a Valmet IQ Dilution Profiler that contributes to improved sheet quality and minimized variability. A Valmet Pulp Analyzer will provide fast and precise online updates of key fiber and papermaking furnish properties.
“To be able to reach the targets, grade conversion modernizations require thorough expertise. Valmet is one of the few suppliers who can design, manage and deliver this kind of vast grade conversion projects.
Additionally, Valmet’s pilot plant played a substantial role since we could demonstrate the technologies to the customer in real life conditions,” says Mike Gray, Valmet’s area vice-president in North America.
Kruger Packaging L.P. is a Canadian manufacturer of containerboard and packaging products made from recycled fibers. The company currently operates one containerboard mill in Montreal, as well as two packaging plants in LaSalle, Que., and Brampton, Ont.
