NORTHBROOK, Ill. -- KapStone Paper and Packaging Corporation announced on Thursday the completion of a $29 million investment at the company's North Charleston, SC, paper mill.

The primary project in this investment was the replacement of the press section on No. 3 Paper Machine which improves the capability and efficiency of producing Ultra High Performance (UPL) lightweight linerboard grades. The new press section was supplied by PMT Italia. The investment also included projects in the fiber and utilities areas to support production of these strategically important grades.

The installation and startup of the new press and the supporting projects were completed on schedule in early February.
