Certified Home-Compostable HEROPACK shipping mailers in black.
Looks and feels a lot like plastic, but it is not! It is a 100% home-compostable shipping mailer and is made from 70-80% PBAT and 20-30% PLA (fancy for cornstarch!)
In a commercial compostable environment, it will break-down within 90 days. At home, it may take up to 120 days.
