Please also note the design of our mailers has changed slightly as follows:

  • Smaller HEROPACK logo on the front (our Heroes can now cover our branding with their own if needed). New photos coming soon!
  • Premium matte finish compared to the previous version which was glossy. This is to differentiate our compostable mailers from glossy plastic mailers.
  • Our compostable mailers are still just as tough, durable and amazing as always!

This is our classic HeroPack shipping mailer in Black. 

It looks and feels a hellavalot like plastic, but it's not. Not even close. It is a 100% biodegradable, home-compostable shipping satchel and is made from 70-80% PBAT (a co-polymer that is completely biodegradable) 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.

We offer custom packaging options with minimum order quantities starting from 10,000 pieces. Samples take 1-2 weeks. Production takes 2-5 weeks depending on order volume. Shipping takes 2-3 weeks. Overall, the custom mailer process from start to finish takes 5-10 weeks and this time frame varies from order to order due to the different requirements of our heroes (clients). Prices start from $0.22 per mailer. Setup and sample costs apply.

Please email us at with your requirements.

We have a price-beat guarantee (conditions apply), so whatever your custom requirements are and whatever deadlines you're working with, get in touch and we're confident we can assist!


About Us

Open tab

We are Anaita and Vik, a superhuman team of elite composters. Well, part of that is true. In real speak, we are a husband and wife duo who are committed to removing plastic from packaging and shipping in Australia. We knew there had to be another way to package items without plastic, so we looked for an Australian eco-friendly shipping solution. And we looked. And we looked. And we looked. And we came up empty-handed. 

So, we began our mission to create shipping mailers that fulfilled our requirements. We worked hard to find supply chain partners who not only use completely renewable materials, but also have environmentally ethical practices and processes. 

We have learnt along the way that recycling is not enough. 90% of plastics and food scraps end up in landfill, and in that environment, they turn into methane which is a deadly enemy of our Planet. So, we decided to specialise in mailers that were 100% home compostable, but also made from such materials that if they ended up in landfill, they would still break down with no waste.

We would love you to join to our League of Heroes on our mission to save the Earth. Even if you’re not ready to buy, but would like to have a chat about how it all works, please email us anytime at
