Jul 24, 2012. /Lesprom Network/. U.S. total printing-writing paper shipments decreased 8% in June compared to June 2011. Shipments for coated free sheet and uncoated mechanical grades posted double-digit year-over-year decreases compared to last June. U.S. purchases (shipments + imports – exports) of printing-writing papers also decreased 8% in June, as the American Forest & Paper Association said in the press release received by Lesprom Network. Total printing-writing paper inventory levels decreased 4% from last month, primarily due to double-digit decreases among the mechanical grade papers. The American Forest & Paper Association is the national trade association of the forest products industry, representing pulp, paper, packaging and wood products manufacturers, and forest landowners.
