United Biscuits has announced a £10m investment in its Jacobs Cream Crackers site in Aintree, Liverpool.
The investment comes as part of a wider plan to modernise and boost overall output within the firm’s UK operations.
The 101-year-old factory will be transformed into a centre of excellence for savoury brands.
A representative for United Biscuits said: “The £10m is capital investment that will go towards general repairs and maintenance to the site’s buildings.”
The scheme to update the factory follows a dispute over sick pay and rumours that production would be outsourced last year.
The Aintree plant houses 800 employees and manufacturers products such as Mini Cheddars, Club and Twiglets.
In 2014 the firm was sold to Turkish company Ylidiz for £2bn.
