A WORSLEY packaging company has found the recipe for success in the food industry.

Mister Blister's Virtuweld range of salad and sandwich boxes have a unique patented locking system.

The packs can be sealed easily and inexpensively, and are presently used by Marks and Spencer.

Now the firm is set to market the system to the wider food industry. Gary Briscoe, managing director of Mister Blister on the Wardley Industrial Estate, said: "The response to the Marks and Spencer packs has been phenomenal.

"We are very excited about the potential applications for Virtuweld within this sector."
