Ready to ditch plastic mailers for something greener? You’re not alone. More brands are switching to compostable mailers and other eco-friendly packaging to cut waste, reduce costs, and show customers they care about the planet. Before you make the switch, it’s important to understand what compostable really means, and how to use biodegradable shipping packaging the right way.
Here’s everything you need to know.
1. What Are Compostable Mailers Made Of?
Compostable mailers are usually made from:
-
PLA (a corn-based bioplastic) – a plant-based plastic made from corn or sugarcane, adding flexibility
-
PBAT (a biodegradable polymer) – a biodegradable polymer that increases strength and durability
-
Kraft paper or other plant-based fibers – providing a natural, recyclable look and feel
These materials break down into water, CO₂, and organic matter, leaving behind no harmful microplastics.
✅ Bonus: Some compostable mailers are even home-compostable, making them easy for customers to dispose of responsibly.
2.What’s the Difference between Compostable vs. Biodegradable
Many people think compostable and biodegradable are the same, but they’re not.
-
Biodegradable mailers will eventually break down, but it might take years and often leave behind plastic residue.
-
Compostable mailers are designed to decompose much faster, with no toxic waste — usually within 90 to 180 days in a proper compost environment.
Always look for certifications like BPI, TÜV Austria, or EN 13432. See the EPA’s guide on compostable plastics.
3. How Durable Are Compostable Mailers?
Stronger than they look! Compostable mailers are:
-
Water-resistant
-
Tear-resistant
-
Lightweight and flexible
They’re perfect for shipping clothing, accessories, and other soft goods. For example, many apparel brands now use durable compostable packaging to replace plastic poly mailers. If you’re shipping sharp or fragile products, you may need extra padding or choose a sturdier eco-friendly option.
4. How Should Customers Dispose of Them?
This is where clear communication matters.
Home compostable mailers can go in backyard compost bins.
Industrial compostable mailers need to go to a commercial composting facility.
Be sure to label your packaging clearly and educate customers on how to dispose of it properly. Adding a simple disposal icon or QR code on your package can make a big difference.
5. Why Your Brand Should Care
Today’s customers are looking beyond the product — they care about how it’s packaged. Switching to biodegradable shipping packaging:
-
Reduces your brand’s environmental impact
-
Improves your customer experience
-
Sets you apart from plastic-heavy competitors
And let’s be real — nobody wants to unwrap a sustainable product wrapped in plastic.

FAQs

2. How long do compostable mailers take to break down?
Most certified compostable mailers decompose within 90 to 180 days in a commercial composting facility. Home-compostable mailers may take a bit longer depending on temperature and conditions.
3. Can compostable mailers handle heavy or fragile items?
Compostable mailers are strong, water-resistant, and tear-resistant, making them perfect for clothing, accessories, and other soft goods. For fragile or sharp items, you may need added protective packaging.
4. Do compostable mailers cost more than plastic mailers?
While they may have a slightly higher upfront cost, compostable mailers can lower costs long term by improving customer loyalty, meeting compliance standards, and reducing waste management fees.
5. How should customers dispose of compostable mailers?
If the mailer is certified home-compostable, it can go in a backyard compost bin. Industrial-compostable mailers should be sent to a commercial composting facility. Clear labeling on the mailer helps customers know exactly what to do.
