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 
  (we have this to make sure your customers know you're using compostable mailers, and also working with the best supplier in town! But if you prefer to just have your own branding, simply cover the logo with your shipping labels :-)
• 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 now mentioned on the back for ease of re-ordering.
• Are you looking for customised mailers with your own brand logo? Check out our page.
• Our compostable mailers are tough, durable and amazing!

• Please note: Shelf life is 9-12 months. We recommend you buying for a 6 month usage period.

Please note: If you're shipping any products which have sharp corners or edges (such as shoe boxes), it's best to trial a couple of shipments with our mailers to ensure everything performs as expected. In order to remain certified home-compostable, our mailers can't be too thick like evil plastic mailers, so sharp corners could sometimes cause damage. Other than that, HEROPACK mailers have a high weight load rating and can withstand all the hard knocks during the shipping process.

Product shelf life: as our compostable mailers are made using renewable ingredients, they have a shelf life of approximately 9-12 months when kept in cool and dry conditions, out of direct sunlight. This should be considered when ordering mailers in bulk. We recommend ordering for a 3-6 month period of shipments.

Please note: These mailers are translucent. We highly recommend packaging your products in a bag or wrapping that is opaque so the products can't be seen through the packaging. 

The translucency of the HEROPACK material is due to the nature of the renewable ingredients used. There are strict rules to be in compliance with the Australian home-compostable certification from ABA, and this is the most important factor for us. If you are looking for no transparency, we recommend our
