MATTHEWS, NC– Exopack Advanced Coatings has doubled its production workforce within the first year of relocating operations from South Hadley, MA, to Matthews, NC. Exopack believes the move will eventually give it the ability to develop new product lines. Three core lines from the South Hadley plant already have been integrated, including phototools; conductive products that cover medical, whiteboard and battery current collector material, as well as all microfilm products.
