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.
The material is based on nature-inspired polymers – “safe and sustainable by design” – and a novel, patentable crystal nucleating agent. This additive 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.
