MeadWestvaco, the paper and packaging giant, said today it is shutting down its envelope manufacturing plant in Enfield, a move that will cost 134 people their jobs.

The plant, which makes and distributes envelopes for billing, financial and direct mail companies, will cease operations within the next two months, the Virginia-based company said in a statement today.

The company, which had already cut jobs at the plant in 2008, had said earlier this month it planned to cut costs through an "accelerated strategic cost management plan" to lower its expenses. As part of the plan, it is also streamlining envelope operations at its Atlanta, Ga.-based facility and restructuring its sales arm in Springfield, Mass., for a total of 190 jobs affected.

Full-time employees laid off will be eligible for severance packages.

Union officials will negotiate the separation benefits for hourly employees, the company said.

Production and equipment at the Enfield plant will be transferred to the company's other facilities.

"The company's capacity to service customers and supply products will not be affected," the statement said.
