Product Details

Description

Discover the powerful combination of sustainability and performance with our ultra-lightweight compostable mailer bags—designed to lower postal costs while supporting a cleaner planet. Made from an eco-friendly blend of 70% PBAT, 5% PLA, and 25% cornstarch, these bags comply with globally recognised compostability standards including ASTM D6400, EN13432, AS4736, and AS5810.

In ideal composting conditions, the bags break down completely within 90 days, turning into nutrient-rich organic fertiliser with zero harmful residue. They are suitable for both home composting (6–12 months) and industrial composting (3–6 months), giving users total flexibility in disposal.

With a 12–18 month shelf life from production, these durable mailing bags offer a premium alternative to plastic mailers. At 60–65 microns, they deliver a strong, high-end feel while remaining moisture-resistant, puncture-proof, and tear-resistant—perfect for eCommerce and retail shipping.

Featuring all-season adhesive strips, the bags seal securely for tamper-evident protection and ensure privacy in transit. If you're looking for packaging that aligns with environmental values without compromising on strength or style, our compostable mailers are the ideal solution.
