Designed for a Range of Shipping Needs

Not all shipping requirements are created equal, and that’s exactly why we designed our padded mailer with flexibility and function in mind. Whether you’re a boutique retailer, subscription box service, or a growing e-commerce brand, our padded mailer bags are tailored to fit a wide range of product types and shipping demands.

Each mailer is constructed from durable, recycled paper, with a smart inner wrap that cushions and protects during transit. Unlike plastic bubble mailers, which rely on synthetic air pockets for protection, our padded bag uses layered paper padding that naturally fluffs up as the package moves. This provides shock absorption and surface protection for soft or semi-fragile goods, without the landfill burden.

These biodegradable mailers are especially ideal for shipping:

• Apparel and textiles
• Art prints and flat paper goods
• Jewellery and small accessories
• Personal care items
• Gift packs and soft bundles

Because they’re slim yet protective, our padded mailers help reduce bulk in your shipments, potentially qualifying your packages for Australia Post Large Letter rates. That means lower postage costs, especially on smaller items like t-shirts, greeting cards, and accessories.

And thanks to their flexible shape and self-sealing closure, packing is quick, clean, and frustration-free.

No tape, no plastic, no hassle. Just smart, eco-friendly packaging that protects your products while reinforcing your commitment to sustainable shipping.

Whether you’re sending five packages a week or five hundred, our recycled padded mailers offer the reliability and efficiency you need to scale your business while minimising your environmental impact.

Sustainable Without Sacrifice

Switching to biodegradable packaging shouldn't mean giving up on quality. Our padded mailers perform just as well, if not better, than traditional bubble mailers.

Key Environmental Benefits

• Recycled Content: Sourced almost entirely from post-consumer paper, giving existing materials a new life.
• Compostable Construction: Breaks down naturally in compost bins, no microplastics or residues.
• No Plastic: Unlike standard poly mailers or bubble padded mailers, our padded envelopes contain zero synthetic materials.
• Reusable: Some customers re-use our mailers before disposal, further extending their life cycle.

Your packaging says a lot about your brand. These mailers show that you care about your impact without compromising on presentation.

Padded Envelopes vs Bubble Mailers: What’s the Difference?

If your business is aiming to go plastic-free, our padded bubble mailers (made with paper, not plastic) offer the same protective benefits without environmental downsides.

If you're exploring alternatives to plastic packaging, you’ve likely come across both padded mailers and bubble envelopes. While they may seem similar at a glance, their materials, environmental impact, and overall functionality are quite different. Understanding these differences can help you make the right decision for your business and the planet.

Bubble Mailers: Lined with plastic air pockets (usually polyethylene), a bubble mailer is not recyclable curbside and is often sent to a landfill.

Padded Mailers (HeapsGood): Lined with recycled paper that offers cushioning while being 100% compostable and recyclable.

Material Composition

Bubble mailers are typically constructed from a plastic outer shell with a lining of small air-filled plastic bubbles. This combination makes them water-resistant and protective, but not easily recyclable. Most recycling facilities can't process mixed materials like bubble mailers, and they often end up in landfills.

Padded mailers, like those from HeapsGood, are made entirely from recycled paper, including the inner cushioning. Instead of plastic bubbles, they use a fluffable, layered paper filling that provides shock absorption during transit. This not only reduces waste but also makes the mailers 100% recyclable and compostable, without any disassembly.

Environmental Impact

The biggest difference comes down to end-of-life disposal. Bubble mailers are rarely accepted in curbside recycling, and even when they are, they require special drop-off points. Their plastic content contributes to long-term environmental issues like microplastics and landfill overflow.

In contrast, our biodegradable padded mailers are accepted in most paper recycling streams and compostable at home or commercially. They break down cleanly, without toxins or residues, supporting a closed-loop system that aligns with circular economy principles.

Brand Perception

Using paper-based padded envelopes for your packaging also sends a clear message to your customers. It shows you’re invested in sustainable practices and thoughtful about every aspect of your operation, from product to packaging. For environmentally conscious shoppers, that’s a powerful brand differentiator.

If you're ready to ditch plastic without compromising protection, our padded mailers are the smart, sustainable choice.

A Professional Look Without the Plastic

Packaging is more than just protection. It’s an extension of your brand. At HeapsGood, we believe your shipping materials should look just as good as they perform, all while supporting your commitment to sustainability. That’s exactly what our padded mailers deliver: a clean, high-quality packaging look that customers will appreciate the moment your product arrives.

Our mailers feature a natural kraft paper finish that complements a wide range of brand aesthetics. Whether your business identity leans minimalist, modern, eco-conscious, or artisan, the uncoated, matte surface of our paper mailers makes a striking first impression. Unlike glossy or plastic-based alternatives, which can feel cold or generic, our mailers communicate authenticity and care.

A Surface That Works with Your Brand

The Kraft exterior of our padded envelopes isn’t just attractive. It’s also incredibly functional. The natural tone works beautifully as a neutral canvas, allowing you to:

• Add branded stickers
• Stamp your logo
• Write hand-signed thank-you notes
• Attach printed inserts or a QR code

This versatility makes them ideal for small business owners and independent retailers who want to add a personal, handcrafted feel to their packaging without sacrificing professionalism. For larger brands, the simple look serves as a clean backdrop for bolder messaging or custom printing.

Customisation Options

Want to take your packaging presentation to the next level? We offer custom-printed padded mailers, giving you full control over how your packaging looks. You can showcase your logo, tagline, patterns, or messaging with high-quality print that adheres directly to the recycled kraft surface.

Custom mailers offer several advantages:

• Reinforce your brand identity from the moment the package arrives
• Create a more cohesive and memorable unboxing experience
• Stand out in a crowded marketplace with eco-friendly branding
• Build brand loyalty through attention to detail

With low minimum order quantities and Australian-based printing, custom options are accessible even for small to mid-sized businesses looking to enhance their brand presence.

Reduce Waste Without Reducing Impact

Many businesses assume they need glossy finishes, colored foils, or plastic wrapping to look professional. We’re here to prove that you can achieve that high-end feel with minimal, biodegradable materials. The impact of your packaging doesn’t come from shiny coatings. It comes from thoughtful design, consistency, and the values it reflects.

Consumers are increasingly aware of wasteful packaging and are more likely to support brands that align with their values. Our padded mailer bags send a clear message: your brand prioritises the planet. That’s not just good for the environment, it’s good for business.

Ideal for Direct-to-Consumer Brands

The rise of e-commerce has made packaging one of the most important touchpoints between a brand and its customer. If your business ships directly to consumers, you know that packaging is part of the experience. Our padded mailers provide a tactile, visually pleasing first impression, without relying on plastic or excessive materials.

They’re lightweight, slim, and strong, which makes them easy to stack, store, and ship. Plus, their uniform look adds polish to fulfilment processes, whether you're packing orders yourself or working with a third-party logistics provider.

In short, our mailers prove that sustainability and professionalism don’t have to be at odds. You can skip the plastic and still ship with pride. With HeapsGood padded mailers, your packaging works harder for your brand and does right by the planet.
