The Newark-based envelope manufacturer can now demonstrate that the path taken by raw materials used in its envelopes is compliant with FSC guidelines.

The company now offers the environmentally-friendly stock through its FSC Pure, FSC Mixed and FSC Recycled board and paper envelopes.

Board Envelopes managing director John Fuchs said the certification means "our customers can be confident that not only will they continue to get first class products but that they are also doing their bit for the environment".

He added: "It's important to encourage our customers to play an important role in helping to promote stewardship of the world's forests."
