May 05, 2009. /Lesprom Network/. St. Marys Paper in Sault Ste. Marie, Ontario, has idled two of its three paper machines for inventory-related downtime and temporarily laid off about 60 workers. The production curtailment is expected to last one month, as The Pulp And Paper Canada informed Lesprom Network. The mill produces supercalendered paper for use in catalogs, magazines, and advertising inserts. Mill production will be handled by paper machine, which can produce about 60% of the mill’s 240 thousand tonne annual output.
