YORK (AP) – Paper products maker P.H. Glatfelter has announced the $360 million sale of its specialty paper business unit, which includes a location in York County. Glatfelter says the sale to investment firm Lindsay Goldberg includes facilities in Pennsylvania and Ohio and wood yard operations in Maryland, Ohio, and West Virginia. The York County-based company founded during the Civil War said earlier this year that it plans to focus on growing its engineered materials businesses, which produces such diverse items as food packaging, air filters, and feminine hygiene products. The specialty papers unit employs about 1,800 people and has plants in Spring Grove, York County, and two in Ohio. There were no plans to close the local mill, the top employer in Spring Grove.
