A consultation is underway into the proposed closure of DS Smith’s Wansbrough paper mill in Somerset.
The packaging company announced the move to the mill’s employees on 26 August following a review of the long-term economic outlook.
The firm said it will consult union and employee representatives “to ensure the best possible outcome for all parties”.
A DS Smith spokesperson said: “The process will take into account all possible options for the future of the site. This announcement in no way reflects the commitment and efforts of our employees who continue to support our business.
Founded by William Wood in the 1750s, Wansbrough Mill in Watchet is the largest UK manufacturer of coreboard.
The mill also produces Liner 3, as well as recycled envelope and bag papers.
The total annual production capacity of the mill, acquired by DS Smith in 1986, is around 180,000 tonnes on two machines.
