JLM Global Foods has taken up 23,000 sq ft of additional space at the park as customers around the world embrace healthier living.
The firm is Europe's leading manufacturer and supplier of popped snacks - selling its products to well-known brands and international supermarket groups.
Paul Huggins, chief executive, said: “We are an expanding business and needed more space close to our HQ in Darlington and Lingfield Point provided the ideal location.
“The logistics here, being so close to road, rail and sea links, are ideal for a company like JLM Global Foods as we have to move stock fast and efficiently.
“We’ve been very impressed with the space and the facilities here – it is extremely secure and yet very accessible which is the perfect combination for us.
“And our staff are delighted there is an on-site canteen – even though we’re never short of a snack or two!”
Julian Brooke, of Lingfield Warehousing and Logistics, added: “We are really delighted to welcome JLM to Lingfield Point.
"They join a growing number of national and international firms choosing to base themselves with us.
“Our continuing success is due to our ideal location, great infrastructure, flexibility in terms of both space and leases and the unrivalled security we offer - from CCTV, to 24-hour security and gated entrances.”
