WestRock Company announced plans to build a new corrugated box plant in Longview, Washington, to meet the growing demand from WestRock's regional customers in the Pacific Northwest. The new plant will serve all industry segments and markets in the Pacific Northwest. When completed, this new plant will replace the company's existing corrugated operations in Longview.

The new plant will be co-located with the Longview paper mill operations and will increase the integration of the mill's containerboard.
