Cardboard Mailer


Sealable - Home Compostable - FSC Paper - Printed with Soy-Based Inks

Offer your customers a low impact shipping solution with our cardboard mailers. Made from unbleached FSC paper, the paper mailer can be added to the home compost or the paper waste recycling stream. Our paper-based alternative to petrochemical plastic mailers have been thoughtfully designed to be sturdy during freight, offering a reliable and regenerative shipping solution. 

Why use a cardboard mailer?

  • Paper mailers last; bioplastic mailers don't. Unlike paper mailers, bioplastic mailers become brittle after 12-15 months and need to be carefully stored. 
  • Recyclable 
  • Reusable
  • Home or commercially compostable

Salt of the Earth cardboard mailers also have a sticky strip to allow the sealing of your packaged products with ease. Please note the backing strip needs to be added to soft plastics recycling or general waste. We are working on this.
