What exactly are they made from?
HEROPACKS are made from home-compostable materials, mainly corn starch and PBAT (a compostable ingredient which bonds the renewable ingredients together).
How do we compost them?
To compost them at home, it’s best to remove any labels, cut them up and place in your compost bin as “brown” materials. These will completely break down within 90-120 days in a home-compostable environment - sometimes even sooner!
These can also be sent to composting facilities to be properly broken down and composted. If you are in Australia, please CLICK HERE to find a composter near you. You can also ask your local council if they can provide a composting green bin for you. Another great option is to visit www.sharewaste.com to find a local home-composting enthusiast near you!
What happens if they end up in landfill?
The best part is that they still break down in landfill. Unfortunately, due to the nature of the landfill process, this will still add to methane production. That's why it's important to help your customers compost our products to take full advantage of the environmental benefits. Our products take about 2 years rather than 90 days to break down in landfill. In contrast, traditional plastic shipping mailers take 400 years or more to break down, and still release deadly methane gas into the atmosphere.
How do your mailers compare to Australia Post (Auspost) mailer sizes?
Australia Post has the following sized mailers:
500g - 220x355mm
1kg - 265x385mm
3kg - 310x405mm
5kg - 435x510mm
The closest mailers we have are as follows:
500g - Use our Small-Medium mailer (220x340mm)
1kg - Use our Medium mailer (265x380mm)
3kg - Use our Medium (265x380mm) or Large (360x480mm)
5kg - Use our X Large (550x550mm)
When you purchase HEROPACKs, you are purchasing the mailers only (not the shipping). To pay for shipping, you will need to go to an Australia Post shop and get labels printed or if you use e-Parcel or Sendle, you can print and pay for labels at home.

What happens in water?
They are water resistant but if they are placed in water for a long time, they will break down there too. It takes much longer to break down in water because of the cooler temperatures.
How can I tell my customers about the compostable packaging?
If you place an order with us, you will receive a link to our Retailer Media Pack, including images and information sheets to send to your customers and/or display on your website.
Are the white strips covering the adhesive also compostable?
The white strips are not currently compostable so should be commercially recycled. However, once your customers receive the mailers, the white strips covering the adhesive have already been removed, leaving the compostable mailer for your customers to home or commercially compost. In order to recycle, find a commercial recycling provider near you.
What's the difference between compostable and biodegradable?
In short, a biodegradable product simply breaks down into smaller micro-plastics which still contaminate the environment. Certified home-compostable products break down as if they were never there, and can also be safely eaten by worms. Therefore, a compostable product is always more preferable over a biodegradable product.
