Weyerhaeuser has sold its container-board packaging and recycling unit to International Paper for $6-billion.

The sale includes nine mills, 72 packaging locations, ten specialty-packaging plants, four kraft bag locations and 19 recycling plants.

Four locations in Kentucky are affected, a container-board mill in Henderson, packaging locations in Bowling Green and Louisville and a specialty packaging plant in Richwood.

Weyerhaeuser said it plans to use a good part of the sale's proceeds to pay down debt as it focuses on its timber, wood products and real estate operations.
