Its Virtuweld packaging is used by the likes of Marks & Spencer for sandwiches and salads. It is also used for DIY products, mobile phone accessories and sports and leisure equipment.
Virtuweld has the look and feel of a welded pack, using a locking system which clamps the front and back securely.
It can be produced more cost effectively than traditional welded packaging, as it does not require glue, staples or other bonding materials.
The product was launched four years ago and is manufactured under licence in the United States and Ireland, as well as at Mister Blister's 4.5-acre site on the Wardley Industrial Estate, Worsley. The company has also granted manufacturing licences to Northern Foods and Adams Pork Farms.
As Virtuweld addresses tamper and freshness issues, demand for it is increasing, with packs distributed in France, Spain, Ireland and the UK.
Now the company, which turns over £3m and employs 50 staff, is looking to increase production and has secured funding from the Royal Bank of Scotland.
Managing director Gary Briscoe, who bought Mister Blister 21 years ago, said: "Since we launched Virtuweld, the demand for it has been overwhelming and this has made it essential for us to increase capacity and develop our facilities.
"The funding we have secured will enable us to continue our strategy of upgrading the factory to compete for larger volume business."
Ed Clivery, business development manager at RBS Commercial Banking, said: "Mister Blister is a good example of a strong local business that has grown to be a leading player in its market.
"We are pleased to have agreed a deal to support its growth plans."
