Encirc, which makes bottles for a range of suppliers including Diageo and Britvic, traded as Quinn Glass until owner Sean Quinn lost control of the firm in 2011 when it went into receivership.
The consortium of banks and investors that bought it have been selling off parts of the group – the packaging business went to the Quinn Business Retention Organisation, while the radiators business went to Irish industrialists.
Spanish bottle manufacturer Vidrala has now emerged as the preferred bidder for the Encirc bottle and jar making business that employs 1,100 people in Cheshire and Northern Ireland.
Encirc said the preferred bidder had “said in the strongest possible terms that it is of the utmost importance to them to integrate with the local communities and keep employment in the relevant regions”.
Jimmy Kelly from union Unite said: “We welcome the announcement that the preferred bidder will retain the factory’s local management team.
“Such an investment provides considerable surety as to the long-term commitment of the bidder to the plant.”
