Product Overview

About Biodegradable Poly Mailers

Ditch the plastic. Our custom biodegradable poly mailers are made from compostable cornstarch-based PBAT and PLA resins. Waterproof, tear-resistant, and featuring a self-seal adhesive strip. Low 500 MOQ.

Align your e-commerce shipping with zero-waste goals using custom biodegradable poly mailers. Made from a blend of cornstarch-based PLA (polylactic acid) and PBAT (polybutylene adipate terephthalate) resins, these shipping bags perform exactly like traditional plastic mailers — offering high tear-resistance and waterproof protection. Key fact: These mailers are fully certified compostable, breaking down completely inside home and commercial compost piles without leaving toxic residue. Featuring a self-sealing adhesive strip, they print beautifully with soy-based inks starting at a low 500-unit minimum.

  • Self-Sealing Adhesive flap: Features a peel-and-seal strip for fast, secure shipping assembly.
  • Organic Soy-Based Inks: Printed using non-toxic inks, preserving compostability and soil safety.

Common Questions

Frequently Asked Questions

Everything you need to know about Biodegradable Poly Mailers. Can't find the answer you're looking for? Chat with our AI consultant.

Our mailers are made from a blend of PBAT (polybutylene adipate terephthalate, a fully compostable synthetic polymer) and PLA (polylactic acid, a plant-based plastic made from cornstarch).

In a home compost pile, they decompose fully within 180 days. In a commercial composting facility, they break down in about 90 days. They leave zero toxic residues or microplastics.

Yes! They offer the exact same tensile strength, puncture-resistance, and waterproof protection as traditional LDPE plastic mailers, keeping your garments dry. Every custom biodegradable poly mailers order at Cubit Packaging is built to your exact specifications with PLA/PBAT Compostable Film (2.5mil), Heavy-Duty PLA/PBAT (3.0mil), Recycled Post-Consumer Poly, Paper Mailer Alternative, free CAD dielines, a digital 3D proof, and DDP doorstep delivery.

Because they are made from biodegradable plant resins, they begin to lose strength after 12 months. Keep them in a dark, dry, cool storage zone before use.

Yes! If you select our "Dual Adhesive Strip" option, the bag features two self-seal strips. Customers tear open the first seal and can use the second seal for return shipping.

Our minimum order quantity (MOQ) for custom biodegradable poly mailers starts at 500 units (with baseline pricing from $0.28/unit depending on size, material, and print specs). Digital printing supports low-minimum runs with zero plate fees, while offset, flexographic, and rotogravure production unlock steep volume discounts at 1,000, 5,000, 10,000, and 25,000+ units.
