About the material

Simplelifeco Board Backed Envelopes are made from sustainably sourced paper and card from well managed forests.

Following our successful certification, our envelopes have met the strict criteria of the FSC® Chain of Custody and are permitted to be advertised and labelled with the tick tree logo.

How to dispose

Paper and card are widely recycled, so you can put your used envelopes in with your kerbside recycling. Or if you have green fingers, you can shred them to add to your compost heap!

Not only does paper and card help to soak up any excess liquid in the compost, but it can provide an excellent source of carbon. A healthy compost thrives on a ratio of 25 parts carbon to 1 part nitrogen. Since paper and card are almost entirely carbon, they can help to balance a compost that has a little too much nitrogenous matter like fruit and veg scraps.


We provide same day dispatch on all orders before 2pm Monday - Friday. It's a next day service and also FREE for all UK mainland orders.

As a proud-to-be-green business, we ship all of our orders in our very own eco friendly, zero-waste packaging and for larger orders, we reuse pre loved boxes and use water activated paper tape.

Why Simplelifeco?

We’re on a mission to provide a greener future for our planet, and over the last year we’ve helped support the planting of 5,000+ trees. Since launching our website, we’ve partnered with Ecologi and continue to plant a tree for every order we get. It really is “buy one, get one tree” here!

Working closely with all of our manufacturers, we’re always striving to reduce the amount of waste that reaches landfill, and in 2021 we pledged to become net zero by 2030 through the SME Climate Hub.
