Frequently Asked Questions About Custom Compostable Poly Mailers
Everything about cost, certifications, and how compostable film behaves in the real world.
Are Custom Compostable Poly Mailers Certified?
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 Are Custom Compostable Poly Mailers Made From?
All EcoPackables Compostable Mailers are made from D42 Film. This bio-based film offers excellent strength, printability, and water resistance while remaining 100% compostable and plastic-free.
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.
How Much Do Custom Compostable Poly Mailers Cost?
Our minimum order for custom packaging starts at $2,500. Pricing per unit varies based on the product specifics, including size, print method, and any added features. Custom compostable polymailers typically starts around $0.08 per unit, but we’ll provide a tailored quote once we understand your project needs.
What Is the Shelf Life of Compostable Poly Mailers?
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.
How Can I Customize My Compostable Poly Mailers?
Absolutely. We offer custom sizes, colors, and thicknesses (from 30–110 μm), along with two-sided or full-bleed printing using eco-friendly vegetable-based inks. You can also add tear strips, double adhesive closures, and custom color options to match your brand’s look.
What Are the Minimum Order Quantities?
Yes. The minimum custom order is 5,000 units, with a daily production capacity of up to 35,000 units. We also offer sample kits so you can test the material and print quality before placing a bulk order.
Are Compostable Poly Mailers as Durable as Regular Plastic Mailers?
Yes, within their intended use, compostable mailers are strong, flexible, and water-resistant. They provide excellent protection for apparel, cosmetics, and other soft goods. However, because they’re designed to decompose, we recommend using them within one year for optimal performance.
How Should Compostable Poly Mailers Be Disposed Of?
These mailers should be placed in a home or industrial composting facility where available. They will fully break down within 90–180 days depending on conditions. Avoid putting them in regular recycling bins, as compostable materials are not compatible with traditional plastic recycling streams.
D42 is an opaque compostable film, made from cornstarch and PBAT, a bio-based polymer. Fully sealable and printable, it is offered in thicknesses from 30–110μm with customizable colors. It is ideal for use in shipping mailers.
