The name “Biopolyesters” refers to a range of biodegradable and compostable thermoplastic polyesters that can be partially produced from annually renewable biomass such as sugarcane.
The plan is for them to be 100% biobased within a few years.
They offer a combination of mechanical properties and biodegradability, suitable for applications such as flexible and rigid packaging or agriculture.
Properties
- Up to 50% biobased
- Biodegradable and compostable in various environments
- Flexible
- Food contact
- Opaque to translucent
