What's the difference between poly mailers and paper mailers?

Poly mailers are lighter, lower-carbon and cheaper per unit, including under weight-based EPR fee schemes, and are recyclable through soft-plastics collection. Paper mailers are FSC-certified, kerbside recyclable, rigid and water-resistant, with a premium tactile finish. Poly protects better against moisture; paper offers the easiest end-of-life story for customers. Many brands run both, matched to product type and market.
