Ready to ditch plastic mailers for something greener? You’re not alone. More brands are turning to compostable mailers as a low-waste, high-impact swap that looks good and feels even better.
But 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)
-
PBAT (a biodegradable polymer)
-
Kraft paper or other plant-based fibers
These materials break down into water, CO₂, and organic matter — leaving behind no harmful microplastics.
✅ Bonus: Some compostable mailers are even home-compostable.
2. Compostable vs. Biodegradable — What’s the Difference?
Many people think they’re the same, but they’re not.
-
Biodegradable means it will break down eventually — but it might take years and leave behind plastic residue.
-
Compostable means it breaks down 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.
3. How Durable Are Compostable Mailers?
Stronger than they look! Compostable mailers are:
-
Water-resistant
-
Tear-resistant
-
Lightweight and flexible
They work great for clothing, accessories, soft goods, and non-breakable items. But if you’re shipping sharp or fragile products, you may need extra padding or choose a sturdier eco 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.
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.
Final Thoughts
Switching to compostable mailers is a simple but powerful move for any business. It shows your brand walks the talk when it comes to sustainability — and that you’re thinking about the planet with every shipment.
