One of the nation’s major manufacturers of corrugated packaging, paperboard, and containerboard has been bought out by one of its competitors.

Creve-Coeur based Smurfit-Stone Container Corporation has been sold for $3.5 billion in stock and cash. It’s been sold to Rock Tenn Company about seven months after coming out of bankruptcy reorganization. 

Smurfit-Stone has about 800 employees in the St. Louis area, and almost 18,000 in all of its facilities.
