Sustainable Materials

Sustainable products do not deplete or degrade the environment. We can rely on using these products into the future, at the same time reducing our environmental impact and ecological footprint.  All our padded envelopes are sourced with FSC (Forest Stewardship Council) Certification.  This is a global certification system that lets the user identify materials from well managed forests and ensures a standard from timber and pulp up through the process chain, whilst offering full traceability.


Our paper and cardboard-based products are recyclable and accepted as household recycling.  Our polythene and other plastic products are also recyclable. If they are not accepted as household recycling, they can be dropped at recycling centres.  Mixed products like padded envelopes are recyclable once the paper is separated from the plastic.  Recyclable products can be made into something else, reducing landfill waste and saving on raw materials, all helping the environment.


All our book wraps, all board and board-backed envelopes, integrated labels and postal tubes are biodegradable.

Biodegradable packing is free from toxins and allergens, it is lightweight and recyclable so will not need to end up in landfill.  We can also source compostable products, which offer even greater environmental attributes.
