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?

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?

1. Place your order and upload your artwork (optional: use our logo placement template).
2. We email a PDF proof within 2–3 business days.
3. If you ordered a printed sample, it’s dispatched 2–3 business days after you approve the proof.
4. 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.
