C5 Board Mailing Envelope (Kraft Brown)

August 2022 New Style Tear Strip
Our self-sealing board-backed envelopes are 100% recycled, recyclable and plastic free, meaning they are easy to recycle in household recycling.

This envelope is C5 size – measuring approx. 162mm x 236mm (fits A5.) and is suitable for items up to 4mm (perfect for Royal Mail Letter). Opening along the long edge, the self-seal strip has a paper (not plastic) release tape.

Manufactured in the UK from 400g eco board (made from 100% post-consumer waste,) these improved board envelopes now have an easy 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 letter), means these envelopes make great protective postal packaging for a variety of products, including greetings cards/envelopes, art prints, and stationery up to 4mm thick.

However, due to the nature of the easy peel opening strip, these envelopes are not suitable for heavier, bulkier items. For larger items, make sure to check out our larger compostable postal bags and large letter envelopes, plus our new recycled corrugated boxes and 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.

Available in packs of 25 or bulk boxes of 200.
