FSC Certified Board Back Envelopes

Board backed envelopes, made to keep important items flat.

Protect documents, prints and other bend-sensitive products in the post with our FSC-certified board backed envelopes. Combining a sturdy board backing with a paper outer, they add rigidity where it matters while keeping your postal packaging simple and professional.

Available in C5 and C4 sizes, they’re a practical choice for sending documents, certificates, photographs, artwork and prints. The C4 size is particularly useful for A4 items, giving you room to pack them without folding.

Ideal for ecommerce businesses, artists, photographers, designers and offices looking for dependable postal packaging that helps contents arrive flat, protected and presentable.

Keep your prints, documents and creative work protected in transit. These board backed envelopes combine a durable manilla paper front with a sturdy cardboard back to help prevent bending and keep your contents looking their best.

They're practical, professional and easy to use — a simple way to add extra protection without relying on plastic packaging.

Ideal for art prints, photographs, documents, stationery, cards and other flat items that need extra protection from bending during shipping.

A great choice for artists, photographers, makers, online retailers and small businesses sending products that need to arrive flat and presentable.

Available in two sizes:

A5: 148 × 210mm
A4: 210 × 297mm

The sturdy cardboard backing helps keep your contents flat and protected during transit.

Please check your product dimensions before ordering to make sure you've got enough room for your item.

Made from paper and cardboard, these envelopes provide a sturdy, paper-based alternative to plastic-backed mailing options.

They're FSC certified, supporting responsible forestry and sustainable sourcing through the paper supply chain.

The envelopes are also recyclable, making them easier to deal with responsibly once they've reached the end of their useful life.

Recycle your board backed envelope with your paper and card recycling once you've finished with it.

Remove any non-paper materials before recycling and keep the envelope clean and dry.

Please check your local recycling collection if you're unsure whether board backed envelopes are accepted in your area.
