Our compostable mailers have been certified by the main industry bodies to break down within 90 days in a commercial composting environment, and 180 days in a home/community composting environment.
Because our mailers are made out of corn starch and PBAT, a bio-based polymer, they do not leave behind any of the damaging residues that plastics do when they break down. In short, it leaves the earth exactly as you found it!
For disposal, all you need to do is remove any adhesive labels or stickers (unless they are compostable noissue stickers), then simply place your mailer in the compost and allow nature to do its work! If you live in an urban area and don't have a home compost, be sure to check with your local governing body on whether or not they accept certified compostable packaging materials at their facility.
