HeapsGood supplies fully compostable mailers in Australia made from PLA and PBAT. Designed to break down completely in compost conditions leaving no microplastics behind. Available from low minimum order quantities with consistent local stock.

What Our Compostable Mailers Are Made From

Our mailers are produced using a PLA and PBAT compostable resin blend.

• PLA derived from plant based sources
• PBAT compostable co polymer
• Single permanent heat seal adhesive strip
• Matte finish
• 63 micron construction
• 10 month shelf life when stored dry

The adhesive strip is the only component that contains conventional plastic elements. We intentionally use a single strip rather than a double return seal to minimise non compostable material across the product.

Our compostable material is certified compostable under recognised international standards.

• Fully compostable

Compostable Mailers vs Plastic Mailers

Compostable mailers are designed to fully break down in compost conditions leaving no microplastics behind.

Plastic mailers remain plastic based materials even when made from recycled content. They depend on recycling systems and soft plastic infrastructure which can be inconsistent.

Compostable mailers remove reliance on soft plastic recycling streams and are designed for complete biological breakdown at end of life.

Minimum Orders

Stock compostable mailers are available from 50 units.

Custom compostable mailers are available from 10,000 units.
