ICSM, working alongside several organisations including insolvency practitioner Moore Stevens, launched Safety Net last month.

The initiative uses various industry experts to create a package of financial help that includes an initial £15m pot for receivables finance.

Louise Ricketts, chief financial officer at Mainline Flatpacks, said: "We approached ICSM as a direct result of the credit crunch and are now covered against losses of more than £1,000.

"Knowing that gives us the confidence to trade freely. A couple of years ago we had a customer go who owed us a lot of money and it was quite a hard hit. We didn't want that happening again, especially not in today's climate."

Mainline Flatpacks, which turns over around £5.5m, was founded in April 1983 by the Lill family and two other partners, in a bid to fill a gap in the envelope market.

Huntingdon-based Mainline operates from a 4645sqm factory, employs 50 staff and produces 1.6m printed peel and seal envelopes a week.

ICSM managing director Ian Carrotte says: "It is fantastic news that Mainline Flatpacks has chosen Safety Net to help run its business from a much more assured standpoint.

"Now it can continue to seek new business secure in the knowledge there is support in place should anything unexpected occur."
