Padded Mailers 

As an e-commerce business, you have a responsibility to your customers to deliver their orders on time. But you also have a responsibility to the environment. Most of the shipping packaging ends up in the landfills and oceans, and you don’t want your brand to be adding to the rising pollution levels. 

To keep your customers and our environment happy, all you need are HEROBUBBLE compostable padded mailers! 

Biodegradable Padded Mailers 

Our 100% compostable bubble mailers are the ideal solution for shipping more fragile items. With thick outer paper and soft padding, it will ensure the utmost safety of any item inside. 

The padding is made from 70%-80% PBAT – a biodegradable co-polymer, and 20%-30% PLA – biodegradable refined cornstarch. 

HEROBUBBLE padded shipping bags can be easily composted at home. Your customers simply need to cut them up and use them as brown materials in their compost bin. 

In commercial settings, our bubble mailers will break down within 120 days, while they take up to 150 days in home settings. 

Eco-Friendly and Durable 

Our HEROBUBBLE padded shipping bags are biodegradable, yet sturdy and tough. Your items will be well-protected during shipping, keeping their integrity, and staying in excellent shape. 

The padded mailers feature a double adhesive strip, so they’re convenient and easily reusable by your customers. 

Our bubble mailers have a small HEROBUBBLE logo, but you can easily customise the branding to suit your needs. Within 8 to 10 weeks, you’ll get your custom bubble mailers and start wowing your customers and saving the planet! 

Order Your Padded Shipping Bags 

There’s only so much you can learn about our compostable bubble mailers by reading about them. So, order a few samples to see for yourself just how amazing they are. 

Test out different sizes to see which ones suit your products and decide which custom mailer is the best choice for you. 

Contact us and start enjoying all the benefits that our bubble mailers bring.

Please note: The sizing mentioned are external dimensions. The internal width will be approximately 10mm less than the external dimensions. For example, for our Small HEROBUBBLE mailer which is 190mm in width, the internal width is 180mm. Please keep this in mind when purchasing to ensure your products fit.

COVID-19 Update:

Hero Packaging is operating as usual.

Hero Packaging is shipping all orders the next business day as usual.

Delivery delays: Due to high volumes in all postage networks, there may be delivery delays for both Australian and non-Australian orders. Please allow more time for your order to arrive and check your tracking link for the latest information before contacting us. If in doubt, contact the shipping carrier directly to obtain further information. When ordering mailers, it's best to keep additional buffer stock to avoid running out during this time.

Contact us for urgent orders: If you are in urgent need of compostable mailers, we can provide a separate shipping quote (for Australian and non-Australian orders) using other shipping carriers who are delivering faster than our usual carriers. Please contact us if this is an option for you and we can assist. 

Dispatch times:

Hero ships the next-business day! All orders are shipped the next business day once payment has been made. You will receive a shipping confirmation with your tracking details once the order has been shipped.

Delivery times:

Australian orders:

Delivery times: In general, please allow 2-6 business days for delivery once your order has been shipped. Please note that unforseen events such as natural disasters can impact delivery times. Check our website for the most up to date information.

    International orders:

    Delivery times: In general, please allow 5-20 business days for delivery once your order has been shipped. Delivery times vary from country to country and rely on the central postal services in the recipient country. Please note that unforseen events such as natural disasters can impact delivery times. Check our website for the most up to date information.

      Import duties: Orders placed outside of Australia will be classed as an import in the recipient country. As such, you will need to pay the associated import duties and taxes required to clear customs in your country. The shipping carrier assigned to your shipment will contact you using the details on your order when placed. If import duties are not paid by the recipient as required, the shipment will be diverted to commercial composting facilities for disposal and cannot be returned. No refunds will apply in these cases either.

      Pre-Order Information:

      Occasionally, our mailers could be out of stock and move to a pre-order listing. This will be noted when purchasing the mailers and will also be noted in your order confirmation alongside any pre-order items. 

      No Split Shipments: Please note that if pre-order items are purchased together with regular items which are in stock, the entire order will be on hold until the pre-order stock is available for shipping (we cannot partially ship orders). If you wish to place a pre-order as well as purchase available items, it's best to purchase separately to avoid delays in shipping your order.

      You will receive a shipping tracking notification as soon as your order has been dispatched. If you have any questions, please message us for assistance.


      Change of mind: If you have purchased the wrong size, or no longer need your mailers, you may be able to return them for a store credit within 14 days of purchase. Due to the renewable ingredients used and shelf life of our mailers, no change-of-mind returns can be accepted under any circumstances after this period. We have a strict returns process to ensure all returns are received correctly and can be re-sold to other customers. Change of mind returns are also subject to handling and restocking fees and the original shipping cost being deducted from any store credit. If you need to return your mailers, please contact us for further instructions.

      Product issues: Sometimes things don't go to plan. Rest assured we will ensure a fast resolution which can include product replacements, store credits and refunds. If you have any product issues whatsoever, please contact us for further instructions. Generally, we will request photos or a video of any issues to help provide the fastest resolution.

      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 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)

      How does shipping work for HEROPACKs (compared to Australia Post pre-paid mailers)?

      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. If you need any more information, head to our blog post - Check it out here!

      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 a 100% compostable mailer for your customers to home or commercially compost. In order to recycle, find a commercial recycling provider near you. A good option in Australia is visiting to find your nearest deposit location.

      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. 

      Do your compostable mailers have a shelf life?

      Yes. As our compostable mailers are made from 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 when purchasing mailers. We are also working on many mailer design improvements which will see this life expectancy increase in the future.
