This combination of materials is non-toxic and contains no Phthalate or Bisphenol A (BPA). The inputs to our products are also certified free of GMO material


We cannot guarantee the mailers’ performance beyond the shelf life.

In a home compost, the mailer will biodegrade in 3-6 months and can also be commercially composted.

These mailers will be broken down naturally by microbes (biodegradation) in a composting environment. They will NOT create microplastics.
