C4 Board Mailing Envelope (Kraft Brown)

Our self-sealing board-backed envelopes are 100% recycled, recyclable and plastic free, meaning they are easy to recycle in household recycling.

Manufactured in the UK from 400g eco board (made from 100% post-consumer waste,) these envelopes have a convenient peel & seal strip, without the little red strip of plastic commonly found in this style of envelope, making it plastic free and easily recycled. 

The rigidity of the board, plus their convenient size (RM large letter), means these envelopes make great protective postal packaging for a wide variety of products, including greetings cards/envelopes, art prints, stationery, and books – Make sure to check out our compostable display bags and recycled grey-board for more packaging ideas!

These board envelopes are unbranded, ready for your branding using stickers, tape, or a stamp. We have a range of printed postal stickers, to convey your eco-friendly ethos to your customer. Use with our recycled L4 labels which are compatible with Click & Drop. 

This envelope is C4 size – measuring approx. 334mm x 234mm (fits A4.) Opening along the long edge, plus pre-folded depth creases, with an expanding gusset up to 23mm (perfect for Royal Mail Large Letter.)

Available in packs of 25 or bulk boxes of 150.
