The US owner of Kettle Chips is set to plough millions of pounds into beefing up its production facility in Norwich.
Diamond Foods plans to invest around $10m (£6.2m) into the facility - - a move it indicated was due to increased demand.
The company bought Kettle Chips in 2009 from its private equity owner, Lion Capital, in a deal worth $615m.
The latest move comes after a new Jalapeno Chilli flavour of Kettle Chips made its debut last month.
