6 reasons to choose eco-friendly custom mailer boxes for your brand in 2025

Switching to sustainable packaging isn’t just an eco-conscious decision; it’s a smart way to connect with your audience, reflect your company’s values, and even save costs over time. Let’s explore why eco-friendly custom mailers are the perfect fit for your brand and how they can create Unboxing Moments® that resonate with your customers.

Sustainable packaging has shifted from being a niche choice to a mainstream expectation. Brands like Amazon and Innocent Drinks are setting benchmarks with innovative packaging practices, using recyclable, recycled, or biodegradable materials to reduce waste and minimize environmental impact.

​​In the apparel sector, brands like Patagonia and Reformation have also embraced sustainable packaging. Patagonia focuses on minimising its environmental impact by using recycled materials in both its products and packaging. Whereas, Reformation uses 100% recycled LDPE mailers and polybags. This approach not only reduces waste but also aligns with their broader sustainability goals, promoting recycling and environmental consciousness among their consumers.

Eco-friendly mailer boxes crafted from materials like recycled cardboard or kraft paper, embody this trend with their minimalistic designs, eco-friendly inks, and biodegradable coatings. These thoughtful touches make them ideal for brands prioritising sustainability, especially in industries like beauty, fashion, and organic products.

Adding QR codes, messages, or labels to your mailer boxes highlights your sustainability efforts, creating a memorable experience that builds trust and loyalty.

Did you know 74% of consumers are willing to pay a premium for sustainable packaging? Investing in eco-friendly designs doesn’t just align with customer values, it enhances their perception of your brand.

4. Cost-efficiency through sustainability

Think sustainable packaging has to cost more? Think again. While it’s true that some eco-friendly materials come at a premium, switching to custom mailer boxes made from recycled content often doesn’t increase your costs.  In fact, sustainable packaging can lead to long-term savings.

In the UK, policies like Extended Producer Responsibility (EPR) encourage businesses to choose recyclable materials, with paper-based packaging typically taxed less than plastics. These incentives make eco-friendly packaging choices both affordable and forward-thinking in the long run.

5. Help us move towards a more circular economy

Eco-friendly packaging plays a vital role in the shift to a circular economy, where materials are reused, recycled, and repurposed. Recyclable mailer boxes fit seamlessly into this model, helping reduce waste and promote responsible consumer habits.

Leading brands like H&M and Unilever have embraced circular principles with programs like recycling textiles and refillable packaging. By adopting these practices, your brand can align with forward-thinking values and meet the expectations of eco-conscious customers.

By choosing custom mailer boxes that fit within a sustainable, circular model, your brand aligns with future-focused values, appealing to consumers who expect eco-responsibility from the brands they support. If you choose custom mailing boxes that work within this sustainable system, you’re building a brand that’s ready for the future.

6. Customise your packaging to showcase your brand's commitment to sustainability

Custom eco-friendly mailer boxes are the perfect canvas for your brand’s identity. From striking designs and logos to biodegradable inks and compostable inserts, every element can reflect your commitment to the planet.

For example, we partnered with London-based fashion brand L’Estrange to design recyclable premium mailer boxes. Featuring QR codes for hassle-free returns, these boxes not only reduce printed materials but also enhance the customer experience.

Whether it’s adding embossed patterns, soy-based ink designs, or plant-based adhesives, your custom packaging can be both beautiful and responsible.

Thoughtful customisation also makes it easier for customers to responsibly recycle or reuse your packaging, showing them that you care about their experience and the planet.
