WAUSAU, WIS. - Wausau Paper Corp. said Friday it's seeking to sell its mill in Brainerd, Minn., as well as two others in Wisconsin.

The Wisconsin mills up for sale are in Mosinee and Rhinelander. The three mills make paper used for packaging, the food industry, linings and masking tape.

Wausau Paper, based in Mosinee, said the company will begin looking for potential buyers of those mills and cannot comment on timing or terms of any transaction.

The Milwaukee Journal Sentinel reported the company will switch its focus solely to making tissues and paper towels, which are produced at its mills in Kentucky and Ohio. Wausau is investing $220 million at its Harrodsburg, Ky., mill.

Last year, Wausau closed its oldest mill in Brokaw, Wis., which made paper for printing and writing. That move eliminated 450 jobs.
