Simplelifeco mailers are made from a blend of cornstarch and biodegradable polymers.

Following our successful certification, our mail bags have met the strict criteria of the EN13432 European Composting Standard and are permitted to be advertised and labelled ‘compostable’ and also include the seedling label.

Simply pop the used mailer in the food waste collection bin and it will be taken to the industrial composting facility.

In order to be suitable for composting, products and materials need to meet the strict criteria of the European EN13432 industrial standard… which ours do!

In the industrial facility, controlled conditions like temperature and humidity encourage bacteria and their enzymes to digest the compostable polymers as a source of nutrition and your mailer will breakdown in just 6-12 weeks!


This process applies to when you see any certified EN13432 product.

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.

We take great pride in providing the best eco friendly postage bags available, with a professional finish that is unchallenged. 

Each pack is quality checked and you can rest assured our mailers are everything you expect; 100% opaque, completely odour-free & a super simple eco friendly swap.

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.
