Linerboard and Medium

We sell rolls of Boise linerboard or medium to companies that manufacture their own corrugated.  We make unbleached virgin kraft linerboard and semi-chemical medium.  Our container plants consume about three-fourths of our containerboard production, but the remainder is sold on the open domestic and export markets.
