Jul 03, 2008. /Lesprom.com/. Sonoco announced that it will permanently close its Montreal, Quebec, Canada, uncoated recycled paperboard mill, effective August 27, 2008, according to James Harrell, division vice president and general manager, Paper North America. The mill, located at 50, rue des Seigneurs in Montreal, has the capacity to produce 48 thousand tons annually of primarily heavy-weight coreboard that has been principally used for the Company’s internal converting operations. The plant closure will impact 53 employees. The Company will offer severance benefits and outplacement assistance to employees. “The Montreal mill has had a good operating history with excellent employees, and we regret that this decision is necessary. However, a significant downturn in the Canadian paper industry has resulted in a decline in demand for cores and subsequently in coreboard,” Harrell said. “In addition, escalating energy, transportation and chemical costs have further impacted the profitability of the mill making it unpractical to run the mill at less than full capacity. As a result, we have no other choice than to close down operations.” Following the closure, Sonoco will operate 23 paper mills and 33 paper machines globally.
