Kapstone Paper & Packaging Corporation

A maker of containerboard, kraft paper, and corrugated packaging for everything from shipping boxes to product wrapping. Formed in 2005 through a management-led buyout of a paper mill, the company grew through purchases of other mills and corrugated box plants, and later became part of WestRock. Its name comes from combining the words "kraft" and "stone," nodding to the kraft paper process behind its products.
