According to bindery manager Mick Charlton, the company, which is part of the Stephens & George Group, wants to "push further into the trade sector".

He said: "We produce all of the PUR and perfect binding work for Stephens & George, but we are also a trade binder. We haven't advertised very well and I am not sure people are aware of what we are capable of.

"Unless they know us, a lot of people think Stephens & George is one man and his sheepdog out in Wales, but we have 240 staff here."

Merthyr Tydfil-based PPF installed a Sitma 1150 mailing line with an inkjet head in July last year.

PPF accounts for 45 of Stephens & George's staff, while the parent company has a turnover of just under £20m.
