Allied Bakeries has confirmed it will close its distribution centre in Saltney.
The bakery giant - which makes well-known brands like Kingsmill, Burgen and Allinson - announced last month it was consulting on plans to close its Chester Road depot - putting 53 jobs at risk.
Now they have confirmed that the proposal has been accepted and the closure will take place in November.
A spokesman said: “We can confirm that following a detailed review and consultation with our employees and their Union representatives, our proposal to close our depot on the Chester Road has been accepted.
“The closure will take place on 19th November 2016 as part of a programme to improve the efficiency of our bread distribution network.
“We have informed all 53 affected employees and their Union representatives.
“We understand that this will be a difficult and unsettling time for our employees and their families and are doing everything we can to offer them support during this period.
“We are ensuring that every effort is made to help those people affected secure alternative employment, either within other parts of Allied Bakeries operations, including at our bakery in Stockport and a new local distribution operation, or externally in the local area, including the wider network of businesses owned by Associated British Foods.
“Our decision to close the depot in no way reflects the commitment and efforts of those affected.”
Alyn and Deeside MP Mark Tami said: “My thoughts are with all the employees during this unsettling time.
“I must commend the representatives of Allied Bakeries for all their efforts to keep the site open, unfortunately it is a very competitive market and now we must focus on offering the employees who will be affected by this the necessary support – something I’m sure they will receive from Allied Bakeries and the relevant bodies.”
Allied have partnered with Coultons to open a new depot in Caernarfon in Novermber, creating 20 jobs.
