BIOPOLYESTERS

logo NaturePlast

Biopolyesters are a range of biodegradable and compostable thermoplastic polyesters which can be partially produced using annually renewable biomass like sugarcane. They will be 100% biobased in a few years

Properties

  • Up to 50% biobased
  • Biodegradable in different environments and industrially compostable
  • Flexible
  • Translucent
