Navy Blue Shipping Mailers This is our latest certified Home-Compostable HEROPACK shipping mailer in navy blue. Important: Shelf life is 9-12 months. We recommend you buying for a maximum 3 month usage period. It looks and feels a hellavalot like plastic, but it's not. Not even close. It is a 100% home-compostable shipping mailer and is made from 70-80% PBAT (a co-polymer that is completely compostable) and 20-30% PLA (which is a fancy way of saying cornstarch). In a commercial compostable environment, it will break-down within 90 days. At home, it may take up to 120 days. Design features: Small HEROPACK logo on the front Double  adhesive strip so your customers can re-use the bag. Premium matte finish to differentiate our compostable mailers from glossy plastic mailers. You can apply your existing shipping labels or write directly onto the mailer. Waterproof to keep shipments safe from rain. Dimensions of the mailer are now mentioned on the back for ease of re-ordering. Are you looking for customised mailers with your own brand logo?
