Our 100% Compostable Polymailers offer eco-friendly shipping protection, certified for both home and industrial composting. Available in stock sizes and fully customizable.
Stock Options (70 µm):
10 x 13" – Case Size: 1,000 Units (900 units - White)
Our 100% Compostable Polymailers provide an eco-conscious packaging solution ideal for industries like apparel, cosmetics, healthcare, bedding, art supplies, and more. These mailers are crafted from D42 film—a blend of organic materials (cassava root and cornstarch) combined with compostable polymers, ensuring biodegradability without plastics or microplastics. Certified by TUV and ABA, they decompose fully in 180 days in home composting conditions and 90 days in industrial facilities.
Custom options include fully adjustable sizes, two-sided, full-bleed printing (up to 8 colors), tear strips, and thicknesses between 30-110μm. The mailers’ 1-year shelf life maintains their integrity for extended storage, and we offer Kraft paper alternatives that are recyclable and compostable, suitable for higher-volume needs.
Designed for brands seeking sustainability messaging, these mailers also provide water resistance and durability to protect products in transit. Sample kits are available for orders of 5,000+ units to let you experience the quality and eco-friendliness firsthand.

Is compostable packaging good for the environment?
Our perspective on compostable packaging evolves with ongoing research and new findings. One thing remains clear: we can't continue to depend solely on paper and LDPE (plastic) for future packaging solutions. Innovation in materials is essential, which is why we currently offer compostable options. While our present offerings may not be "perfect," the absence of investment from companies like ours would hinder progress toward the ideal compostable material. There are challenges, such as incomplete composting infrastructure and the lack of a strong alternative to fossil-based PBAT, a common binder in many bags. However, without exploring these options and supporting R&D in material science, legislative changes and the development of new materials will stall. For this reason, we see compostable technologies as a crucial investment in the future.
Do your bags contain microplastics?
No, they don’t. Many “biodegradable” plastics are often oxo-degradable plastics. These are produced from conventional non-biodegradable plastics, enhanced with additives that simulate biodegradation to promote material fragmentation. These plastics disintegrate into tiny fragments that persist in the environment. Our bags are completely different — there is no polyethylene structure in the bags. Instead, when they break down, they dissolve into water, organic biomass, and C02.
What are the certifications?
The bags are certified by all three industry certifiers; Vincotte, BPI and Dincerto,
meeting American, European, International and Australian standards – including
certifications for your domestic home compost. To gain these certifications, the
product must break down within 90 days in commercial compost and 180 days in
home compost conditions, including wormfarm compost. After degradation, they
must leave no harmful residues behind. In fact, the only residue left behind is a soil
enhancer which is returned to the earth as plant food.
What is the shelf life?
This is very important. To ensure maximum longevity, EcoPackables mailers should
be stored in a dark, dry place. If stored correctly, they will be strong enough to send
parcels around the world for at least 9-12 months, if not, their strength will be
compromised. This is why we recommend ordering in 6-month intervals.

Solid Mailers
I absolutely love these mailers. The compostable mailers really help our company stand out with our branding and help use live up to our mission a socially responsible organization which customers appreciate. Mailers are very durable and color completely stands out compared to other ones I've used in the past. Highly recommend!
Their D42 Compostable Film is the only one I've found that adheres well to lables, is durable enough to carry the books that I ship, and also have exceptional print quality. I go through a very good amount of these each month, and they never let me down. Would highly recommend these to any business shipping flexibles
As I started selling more, I felt more guilty and more guilty about the amount of plastic I felt I was putting into the ocean. These mailers are such an awesome concept and the fact that they only cost a tiny bit more than the plastic ones is wonderful!
Being closeby in California, we've developed several custom projects with EcoPackables. Our custom side-gusset pouches and recycled kraft mailers were made by them, and I'm very happy with how they turned out. The team of people there are really nice and great to work with. Super on top of the small things and have an incredible passion for sustainability
I have been working with EcoPackables now for over 2 years, and I truly love their products. Their compostable coffee pouches are perfect and have a high enough barrier to keep my products fresh. I now pair these with their compostable labels and bubble mailers for a fully eco solution!
Exactly what I was looking for to ship my clothing in. I sell my old clothes on Depop and this envelope is worth the price! You can write on it and on top of that it’s Biodegradable 💕 you don’t even have to worry about the rain ruining it because of the bubble lining. Will buy again!
They hold up great and are easy to use! Only compostable in industrial facilities but at least they'll break down faster in the landfill. I'll keep ordering them!
Inside dimensions are excellent. No need for extra tape to secure the closing. Some reviews mentioned the words getting in the way of the addresses.... but if you turn it over the front side is completely blank so I'm not sure what is up with those reviews? Overall I'm very happy with these
