In today’s e-commerce world, shipping products safely and affordably is very important. One of the most popular packaging options is the poly mailer. These lightweight bags are strong, water-resistant, and easy to use. But not all poly mailers are good for the environment. That’s why more businesses are choosing compostable poly mailers—a greener solution for modern shipping.
In this article, we will explain what poly mailers are, their types, and why compostable versions are better. As a professional manufacturer of compostable poly mailers, we also share how we help brands switch to sustainable packaging.
What Is a Poly Mailer?
A poly mailer is a plastic shipping bag used to deliver soft, non-fragile items. It is made from polyethylene or other plastic materials. Poly mailers are often used by e-commerce sellers, retailers, and warehouses.
Key features:
- Lightweight and cost-effective
- Water-resistant and durable
- Takes up less space than boxes
- Easy to seal and label
Poly mailers are perfect for shipping:
- Clothes
- Books
- Documents
- Accessories
- Small electronics
Many online stores choose poly mailers because they save on shipping costs. The bags are light and slim, which helps reduce delivery fees.
Types of Poly Mailers
Standard Poly Mailers
Basic plastic bags without padding. They are strong enough for soft goods like clothes.
Padded Poly Mailers
Have a bubble layer inside. The padding protects fragile or valuable items like phones or jewelry.
Returnable Poly Mailers
Two adhesive strips. One for sending, and one for returns. Many fashion brands use them.
Custom Printed Poly Mailers
Printed with the brand logo or design. They help promote brand image.
Compostable Poly Mailers
Made from biodegradable materials like PLA and PBAT. They are eco-friendly and break down in compost.
Problem With Traditional Poly Mailers
- Not biodegradable: They take hundreds of years to break down.
- Pollution: They often end up in landfills or oceans.
- Harm to wildlife: Animals can mistake plastic for food.
As environmental laws get stricter, more companies are looking for sustainable shipping options.
Why Choose Compostable Poly Mailers?
Most poly mailers are made from plastic. These are not biodegradable and cause pollution. If your business wants to reduce plastic use, compostable poly mailers are the answer.
- Are made from PLA and PBAT, not plastic

- Are strong, waterproof, and safe to use

Compostable Poly Mailers: A Greener Choice
Compostable poly mailers are a modern solution for eco-conscious businesses. They look and work like plastic mailers, but they are made from plant-based materials. After use, they break down naturally in industrial or home compost.
What are they made of?
- PLA (Polylactic Acid) – from corn starch
- PBAT (Polybutylene Adipate Terephthalate) – a biodegradable polymer
These materials break down into water, carbon dioxide, and organic matter under the right composting conditions.
Key Benefits:
- 100% Compostable
Breaks down in 90–180 days in industrial compost. - Strong and waterproof
As durable as traditional plastic. - Non-toxic
