Fraunhofer Institute for Toxicology and Experimental MedicineThe EU project BORN is developing a novel, bio-based and biodegradable polymer that, for the first time, can withstand high temperatures of up to 100 °C. This closes a key gap in the field of sustainable packaging materials, as conventional bio-based polymers typically resist only about 50–55 °C.
BORN material is produced via “safe and sustainable by design”, using nature inspired polymers and additives. A novel, patentable crystal nucleating agent enables controlled crystallization during industrial processing and gives the polymer its exceptional temperature stability.
Wide range of applications
Thanks to its properties, BORN is suitable for a broad spectrum of applications, including:
- heat-resistant, compostable food packaging
- microwave-safe containers for ready meals
- cost-effective cups for hot beverages
- agricultural products such as mulch films
- reusable consumer goods and other applications requiring high temperature resistance
Sustainable across the entire life cycle
BORN follows a holistic approach: from the development of sustainable additives and material design to the production of laboratory samples and practical testing as food packaging.
The material is intended to be circular, bio-based, biodegradable, compostable, food-safe, recyclable, and cost-effective – a combination that does not yet exist on the market. The project evaluates its biodegradability in various real and extreme environments, complemented by a comprehensive safety assessment at the end of its life cycle.
