5000 Series

The Natur-Tec®  5000 series is a platform of high-performance, biobased, and compostable polymer resin compounds designed specifically for sheet extrusion used in thermoforming applications, and profile extrusion applications such as compostable plastic straws.  Natur-Tec® resins are certified fully compostable to the stringent requirements of international standards for compostable plastics, including ASTM D6400, EN 13432, and ISO 17088, and provide an environmentally friendly alternative to conventional plastics.

Natur-Tec® 5000 series resins are engineered for high-performance and can be easily processed on standard extrusion equipment.
