International Paper, located at 4725 Easton Road, is investing $12 million in equipment to increase efficiency and capacity.
The decision follows a review by the company's corporate office which evaluated the facilities in Missouri.
The St. Joseph Metro Chamber worked with Buchanan County, the City of St. Joseph and the state to offer a tax abatement on the new equipment and to secure a loan to train employees.
International Paper has 134 employees in St. Joseph. The company produces corrugated cardboard boxes.
