Custom Compostable Mailers
Custom Compostable Mailers — Zero-Waste E-Commerce Shipping
For brands committed to zero-waste logistics, our compostable mailers break down completely in home or industrial composting within 90-180 days. Made from plant-based PBAT and cornstarch materials, they provide the same water-resistant protection as poly mailers without leaving any microplastics behind.
Environmental Certifications
- TUV OK Compost HOME — certified for home composting
- ASTM D6400 — compliant with US composting standards
- EN 13432 — approved under European composting standards
- Printed with water-based soy inks — fully compostable together with the mailer
Performance
Despite being compostable, our mailers deliver equivalent water resistance, tear strength, and seal integrity to conventional poly mailers. Self-seal adhesive strip for fast fulfilment, with double adhesive strip for easy customer returns.
Branding
Custom printing via water-based soy inks in up to 4 colours. Popular designs include brand logo with sustainability messaging and composting instructions — turning the packaging into an educational brand touchpoint.
For other eco-friendly options, explore our sustainable packaging range, eco kraft boxes, recycled rigid boxes, and honeycomb kraft mailers. For corrugated alternatives, see our custom mailer boxes.
