Boise said its packaging segment’s EBITDA for the quarter was $46.9m, posting an increase of 22% from 2010. For the full year it went up to $159.3m, growing 54% year-on-year.

Paper segment sales for the quarter surged marginally by 2% at $359.7m, and full year sales went up by 3%, driven by higher sales volumes of uncoated freesheet.
