Armonk, N.Y.-based Visant Corp. will close a plant in Pennsauken, N.J., and shift manufacturing operations from there to plants in Milwaukee, Hagerstown, Md., and Rockaway, N.J. About 200 people work at the Pennsauken, N.J. plant. The company is still trying to determine what changes will be made at the Milwaukee plant, which is located at 8111 N. 87th St. and does business as Lehigh Milwaukee, said Visant vice president of finance Paul Carousso. However, he said the plant, which makes overhead transparencies for schools and book covers, will see some "incremental increase" in production, which should result in some increase in employment and the addition of some new equipment. Currently, about 100 people work at the Milwaukee plant. More employees will be added at the larger plant in Hagerstown, he said. No employees will be added to the Rockaway, N.J. plant.
