Spanish company Vidrala has bought the former Quinn Glass business for €408.6m.
The business includes manufacturing plants in Derrylin in Co Fermanagh and Elton in Cheshire, England and is currently named Encirc.
It is being sold by Aventas Manufacturing Group, which has managed a number of companies in the former Quinn Group since bondholders moved to take control of the company over debts owed by Seán Quinn.
The sale of the glass business has been met by local opposition, with many fearing it would impact employment and investment in the area.
Paul O’Brien, Aventas CEO said they were “pleased” to have completed the sale and Vidrala would have the “ability and expertise to continue to invest in Encirc” in the years ahead.
