Citing strong demand for packaging products in “a growing U.S. economy and a booming ecommerce market,” WestRock is adding to its holdings. The packaging supplier announced an agreement to buy KapStone Paper and Packaging Corp. for about $3.5 billion.
 
Last year, WestRock purchased Multi Packaging Solutions International Ltd and sold its division that makes soap dispensers and perfume sprayers to focus on its core paper and packaging businesses.
