Key takeaways
- Start with a clear audit of your current packaging — sizes, volumes, failure modes, and what you are claiming to customers.
- Replacement packaging must solve the same fulfilment job before it can add environmental benefit — protection, sealing, carrier compatibility.
- Phasing the transition reduces risk and allows operational problems to surface before they affect large volumes.
- Custom branded compostable mailers are the most direct replacement for conventional plastic poly mailers in most soft-goods categories.
- Running down existing plastic stock before switching avoids waste and simplifies the changeover.
How to reduce plastic packaging in ecommerce: eight steps
Reducing plastic packaging in ecommerce is a manageable transition when approached in a defined sequence. The eight steps below take you from understanding your current situation to communicating the change to customers — with the right decision points at each stage.
- Audit your current packaging — document every format, size, monthly volume, failure mode, and any carrier or 3PL constraint. This baseline defines what the replacement must do.
- Identify failure points — note what is going wrong with current packaging (seal failures, moisture damage, wrong sizes) and ensure any replacement solves those problems before adding environmental benefit.
- Compare alternatives — evaluate recycled plastic, paper/kraft, and certified compostable film against your product type, customer markets, claims requirements, and budget. For a detailed comparison, see the [Compostable Mailers vs Recycled Plastic guide](/articles/compostable-mailers-vs-recycled-plastic-mailers/).
- Test samples — request samples from shortlisted suppliers and test against your actual products, pack speeds, and courier conditions before committing to production.
- Confirm certification — for compostable packaging, confirm the specific standard (AS5810, EN 13432, ASTM D6400), certifying body, certificate number, and whether it is home or industrial compostable.
- Run down existing stock — place the new custom order to arrive as existing plastic stock runs low, with a small overlap. Disposing of usable packaging early is wasteful and adds cost.
- Launch the new packaging — switch as existing stock depletes. Time the switch to align with a product launch, seasonal reset, or rebrand moment where possible, to maximise the brand communication opportunity.
- Communicate clearly to customers — tell them what changed, why, and exactly what to do with the new packaging. For compostable, name the certification and give specific disposal instructions on the mailer itself.
Understanding the alternatives to conventional plastic
The main alternatives to conventional plastic poly mailers for ecommerce brands are recycled plastic, paper or kraft, and compostable film. Each has a different environmental profile, different performance characteristics, and different implications for what you can claim.
Recycled plastic reduces virgin plastic use and is lower cost — but remains plastic at end of life, with limited kerbside recycling available in most markets. It is a meaningful transitional step for brands where budget is the primary constraint. Paper mailers suit dry, flat, non-fragile products and markets with strong paper recycling — but their moisture resistance is limited and some paper packaging includes plastic coatings that make it non-recyclable.
Certified compostable mailers are made from plant-based materials and designed to break down in composting conditions. When certified and correctly disposed of, they offer a different end-of-life pathway from any form of plastic. They are typically priced above recycled alternatives. For brands wanting a specific, defensible, customer-communicable environmental claim, compostable is the strongest available option for most soft-goods categories. For detail on evaluating eco friendly claims, see the Eco Friendly Mailers guide.
What not to do when replacing plastic packaging
The transition from plastic packaging is straightforward when approached correctly — and predictably problematic when approached carelessly. These are the most common mistakes.
- Do not switch material and size at the same time. Changing dimensions and material simultaneously multiplies the specification risk. Get the dimensions right first, then switch material.
- Do not commit to a full production run without testing samples. A compostable mailer that performs differently from conventional plastic in your packing workflow — different feel, different seal timing, different courier compatibility — is far better discovered on a sample than on arrival of 5,000 units.
- Do not make environmental claims before certification is confirmed. Saying 'we now use eco-friendly packaging' before you have confirmed the certification type, certifying body, and specific standard exposes you to greenwashing risk.
- Do not use vague disposal instructions. 'Compostable' without specifying home or industrial, without naming the certification, and without a specific disposal instruction is not useful guidance for customers — and is increasingly scrutinised by regulators.
- Do not dispose of existing plastic stock early. Running down current stock is the right approach — waste is waste, regardless of what material it is.
- Do not skip the supplier question process. Asking for the certificate number, expiry date, and certifying body is the minimum basis for a claim you can stand behind.
How to communicate the switch to customers
Customers in fashion, beauty, lifestyle, and wellness categories notice packaging changes and comment on them — positively when the change is clearly explained, critically when it is not. Getting the communication right turns a packaging switch into a brand moment.
The core message should be specific: what changed, why, and what customers should do with the new packaging. For certified compostable mailers: the material is plant-based, certified to AS5810 (or EN 13432, as applicable), and customers should place it in their home compost bin (or organics collection, as applicable). Include the certification mark on the packaging itself where space allows.
Avoid overclaiming. 'We have switched to certified home compostable packaging to reduce our reliance on conventional plastic' is accurate and credible. 'Our packaging is now zero waste' is not. Specific and honest claims build more trust than aspirational ones that cannot be substantiated. When you are ready to begin, start with the custom compostable mailers enquiry page.
