ecoflex® (PBAT): The original since 1998 – certified compostable biopolymer

ecoflex® is the first biodegradable and certified compostable plastic by BASF on a fossil basis. The biopolymer is on the market for more than two decades. It supports a circular economy by enabling products that are certified compostable and thus advances organic recycling.



ecoflex® is:

  • the ideal blend component for bioplastics
  • certified compostable and biodegradable
  • elastic as well as water and tear resistant
  • processable on conventional blown film machines for polyethylene
  • printable and weldable
  • suitable for food contact

The certified compostability of the bioplastic ecoflex®

Thanks to its special chemical structure, ecoflex® can be biodegraded by microorganisms and their corresponding enzymes. Under the circumstances in an industrial composting plant, the ecoflex® molecules are biodegraded within a few weeks. In special certification procedures, independent institutes test the suitability of bioplastics in terms of biodegradability, compostability, compost quality, and plant compatibility.

ecoflex® offers various product grades that meet international and national standards for industrial composting:

ecoflex® standards
ecoflex® tested quality

High quality: ecologically tested and toxicologically safe

Scientifically recognized tests (e.g. plant growth test, Daphnia test, toxicological tests according to OECD directives) have proven in practice that ecoflex® has no negative consequences for nature or the environment. Furthermore, ecoflex® is in its composition one of the few compostable polymers complying with the requirements of the European food contact regulation (Commission Regulation No. 10/2011 of January 14, 2011) as well as the requirements of the US Food Contact Substance Notification No. 907 of FDA.

ecoflex®  is the optimal compound partner

ecoflex® is an ideal blend component for the production of plastics from renewable raw materials like polylactic acid (PLA), making many applications actually possible in the first place. Thus, ecoflex® provides the bio-based and certified compostable BASF biopolymer ecovio® with special material properties such as flexibility and toughness.

Next to PLA, other compound partners such as starch can be used to achieve a specific profile for the application. A high ecoflex® content is particularly suited for the production of flexible film products for packaging. Mechanical characteristics such as stiffness or puncture resistance can be varied and specifically adjusted.
