One of three UK Field First sites (the others in Bristol and Newcastle produce labels and cartons respectively), it produces packaging for food and household products.
The company says it will consult its customers and, if this proposal is implemented, other Field Group sites will support Oldbury's current customer requirements.
The proposed closure would take place over the next six months and it is anticipated there may be up to 190 redundancies. However, Field says it is expected that this action "may create opportunities at other Field Group factories and it is hoped that some employees may wish to consider these".
Field says it undertook a review of its manufacturing capacity following significant recent investment across its UK carton operations. It says this investment, supported by employee training, "has created world-class manufacturing operations that have the capacity to serve the needs of key market sectors".
