What exactly are they made from?
HEROPACKS are made from biodegradable materials, mainly corn starch and cassava roots.
How do we compost them?
Ideally, these should 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.
To compost them at home, it’s best to cut them up and place in your compost bin (as “brown” materials). These will completely break down within 90 days in a compostable environment.
What happens if they end up in landfill?
The best part is that they still break down (with no waste and no methane production) in landfill. It takes about 2 years rather than 90 days. In contrast, traditional plastic shipping mailers take 400 years or more to break down, and 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)
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 longer to break down in water because of the cooler temperatures.
How can I tell my customers about the biodegradable packaging?
If you place an order with us, we will send you our e-HERO Media Kit, 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 certified compostable so should be discarded. However, once your customers receive the mailers, the white strips covering the adhesive have already been removed, leaving a 100% compostable mailer for your customers to home or commercially compost.
