COMPOSTABLE MAILER BAGS

Compostable mailer bags – a practical alternative to standard packaging

Compostable mailer bags are made from an organic raw material based on lactic acid and starch, with performance characteristics comparable to polyethylene. This material is then processed into a feedstock for the production of eco-friendly films.

As a result, the material retains the key properties required in packaging—flexibility, durability, and moisture resistance.

This solution effectively replaces both standard poly mailers and paper bags without requiring any changes to the packing process. A compostable mailer bag remains lightweight, practical, and quick to use, while also delivering added value where packaging is part of the brand image and the overall customer experience.

Depending on composting conditions, compostable packaging typically takes approximately 3 to 6 months to break down into compost. It also complies with the EN 13432 standard, which defines the requirements for packaging recoverable through composting and biodegradation.
