Teal Shipping Mailers

Finally! Our teal shipping mailers have arrived! This is our latest certified Home-Compostable HEROPACK. 

The teal colour is a mix between green and blue.

It looks and feels 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.

Please note: These mailers are semi-translucent. Please see the translucency image.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 black compostable mailers. 

Design features:

  • Small HEROPACK logo in grey/white on the front
  • 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 Custom Mailer page.
  • Our compostable mailers are tough and durable.

  • Australia: Home Compostable (AS5810) and Commercially Compostable (AS4736)
  • International: Home Compostable (EN13432) and Commercially Compostable (EN13432)

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.

Hero Packaging's HEROPACK teal shipping bags are an innovative, environment-friendly alternative to traditional mailers. The reason? Despite looking and feeling like plastic, they're 100% home-compostable and break down within just 90-120 days. These features alone distinguish them from the dull, wasteful plastic mailers that end up in landfills across Australia.

What Sets Hero Packaging Mailers Apart

The quality of these teal postage bags can't be beaten. They're waterproof, tough, and outfitted with a double adhesive strip that allows them to be reused over and over again. The durability of these mailers comes from their quality materials: a blend of 70-80% PBAT (compostable co-polymer) and 20-30% PLA (cornstarch).
They're also gorgeous to look at and sure to leave a positive impression. Their deep teal colour is a mix between green and blue, and each matte bag is styled with a subtle, grey HEROPACK logo on the front. 

Customise the Size and Quantity of Your Order

We offer our teal shipping mailers in 5 different sizes, all of which are similar to the dimensions used by Australia Post. These include the small (19cmx26cm), the medium 1kg (26.5cmx38cm), and our extra- large 5kg mailers (55cmx55cm). For your convenience, and to get the best value, you can order in quantities of 25, 50, 100, 250, 500, and 1000. With this variety, you shouldn't have any trouble finding a mailer that fits your product.

Can't choose between our multiple sizes? We understand if you'd like to see some samples before committing to a 25+ pack. That's why we offer a HEROPACK sampler containing 1 mailer of each colour and size for a total of 15. This variety pack will help you determine which size and colour mailer is best suited to your product. If you'd like to order in bigger quantities, you're welcome to order your own custom mailers.

Pre-Order Information

COVID-19 Update:

OFFICE: We're operating as usual.

WAREHOUSE: We're shipping orders the next business day as usual.

    AUSTRALIA: Australia Post is currently experiencing some delays in parts of their network due to COVID-19 lockdowns and staff shortages due to COVID-19 positive cases. This is mixed with handling Christmas-peak like parcel volumes nationally. Please order ahead and choose Express Post in checkout if you need products quickly.

    INTERNATIONAL (outside Australia):
    Some delays, depending on COVID-19 outbreaks in destination country.

    There may be delivery delays for 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 non-Australian orders using other shipping carriers who may be delivering faster than our usual carriers. Please contact us if this is an option for you and we can assist.

    Dispatch times:

    Hero ships orders the next business day! You will receive a shipping confirmation with your tracking details once the order has been shipped. Our order system is highly automated, which means we cannot amend or change orders once placed under any circumstances. However, if you need to return mailers, please review our returns information below.
    Please note that unforeseen events such as natural disasters can impact dispatch times. Check our website for the most up to date information.

    Delivery times:

    Australian orders:

    Delivery times: In general, please allow 2-8 business days for delivery once your order has been shipped. Please note that unforeseen 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 unforeseen 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.


        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.

        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.

        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 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. 

        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.
