Weyerhaeuser Co., Federal Way, Wash., agreed to sell its liquid packaging board business to Nippon Paper Industries Co. Ltd., Japan, for $285 million in cash.

The transaction includes one mill located in Longview, Wash., with an annual capacity of 280,000 tons.

This announcement concludes a portion of the strategic review of the company's cellulose fibers business, which was initiated in November 2015. Weyerhaeuser announced the planned sale of its pulp mills in May. The company's review of its printing papers joint venture is ongoing.

"This transaction creates significant value for Weyerhaeuser shareholders, and enhances the focus of our portfolio, as we work to be the world's premier timber, land and forest products company," says Doyle Simons, president and CEO of Weyerhaeuser. "The employees of our liquid packaging board business have much to contribute to the future success of Nippon Paper Industries. I want to thank our team for continuing to operate safely, and for delivering an exceptional customer experience throughout the strategic review process. Our liquid packaging board products and people are celebrated across the industry for their quality."

The transaction is subject to customary closing conditions, and is expected to close in the third quarter 2016. The Weyerhaeuser liquid packaging board mill and Nippon Paper Industries will continue to operate separately until the transaction closes.
