Black Compostable HEROBUBBLE Mailer - From Packs of 25
per unit
Product Description
Black HEROBUBBLEs
Need your products to be protected during the shipping process, but still want that compostable goodness? Then you're in the right place! Our black HEROBUBBLEs are our padded mailers that replace plastic bubble mailers. They have an inner compostable layer of padding and an outer compostable layer.
These mailers are thick and will ensure that your products are nice and snug during shipping!
Home Compostable Padded Mailers
Our compostable black bubble mailers are the ideal solution for shipping more fragile items.
The padding is made from 70%-80% PBAT – a biodegradable co-polymer, and 20%-30% PLA – biodegradable refined cornstarch.
Our 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.
Reusable
A feature that we have added to our padded mailers is a double adhesive strip. This means that, unlike other mailers, your customers can reuse the bag by cutting along flap and then using the second sealable strip to package their products.
Our black bubble mailers have a small HEROBUBBLE logo, but if you want custom branding, then we have you covered! Click to customise the branding.

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.
HEROBUBBLE Padded Mailer FAQs
What is a HEROBUBBLE mailer?
HEROBUBBLE is our compostable alternative to plastic bubble mailers. It has an outer layer of FSC recycled paper and an inner layer of compostable bubble padding, so products stay snug and protected in transit.
What is the padding made from?
The padding is 70–80% PBAT, a compostable co-polymer, and 20–30% PLA, made from refined cornstarch. The outer layer is FSC recycled paper.
Are HEROBUBBLEs certified compostable?
Yes. HEROBUBBLE mailers are TÜV certified for commercial composting. They break down in a commercial composting facility, not a home compost bin.
How long do they take to break down?
Within 120 days in a commercial composting facility.
How should my customers dispose of them?
Remove any labels, then tear the paper outer away from the padded inner. The padding goes to a commercial composting facility (check your council’s organics options); the paper layer can be recycled. Don’t put the whole mailer in the recycling bin. Disposal instructions are printed on the back of every mailer.
What sizes are available?
| Size | External dimensions | Colours |
|---|---|---|
| Small | 19 x 26cm | White, Pink, Black |
| Medium | 26.5 x 38cm | White, Pink, Black |
| Large | 36 x 48cm | White |
Large is our biggest padded mailer.
Will my product fit?
Sizes are external dimensions. Allow about 10mm less on the internal width — for example, a Small HEROBUBBLE (190mm wide) is about 180mm wide inside.
Are HEROBUBBLEs suitable for fragile items?
They give more protection than a non-padded mailer, but fragile items still need an extra protective layer inside, such as HERO Hex Wrap. For very fragile items, use a box instead.
Can I get HEROBUBBLEs printed with my logo?
Yes, white and pink HEROBUBBLEs can be custom printed in full colour (logos or photos) from just 25 mailers. Select “YES – ADD MY LOGO” and upload your artwork. Black HEROBUBBLEs are sold plain.
How does custom printing work and how long does it take?
- Place your order and upload your artwork (optional: use our logo placement template).
- We email a PDF proof within 2–3 business days.
- If you ordered a printed sample, it’s dispatched 2–3 business days after you approve the proof.
- We print your full order after approval: 25–100 units in 3–4 business days, 250–500 in 5–6, and 1,000+ in 7–10.
Have an event or deadline? Contact us before ordering and we’ll let you know what’s possible.
Can my customers reuse the mailer?
Yes. HEROBUBBLEs have a double adhesive strip, so they can be resealed for returns.
Can I write on it or use my own shipping labels?
Yes, you can write directly on the paper outer or apply any shipping label. Our paper HEROTAPE EXPRESS also works on HEROBUBBLEs. A small HEROBUBBLE logo sits on the front; cover it with your label if you prefer.
Do HEROBUBBLEs have a shelf life?
Yes, about 12–18 months when stored cool and dry, out of direct sunlight.
Can I get a sample?
Yes. The Padded Mailers option in our Sample Packs includes one HEROBUBBLE in each colour (white, pink and black). Single sample units are also available on white and pink.
Do you make custom padded mailers in bigger quantities?
Yes. Fully custom compostable padded mailers start from 5,000 units — see CUSTOM Compostable Padded Mailers.
