Exploring Heat-Resistant Biodegradable Packaging: Europe’s BORN Project

Materials & Technology · International Research

For hot-drink cups and hot-food containers, packaging materials need to balance heat resistance, food protection and end-of-life options. Europe’s BORN project is exploring new bio-based, biodegradable materials to expand their use in applications involving higher temperatures.

According to Fraunhofer ITEM’s project overview, the research team is working to improve polymer heat resistance through material formulation and controlled crystallization, targeting temperatures of around 100°C. Potential applications include hot-drink cups, heat-resistant food packaging and microwave-safe containers for ready meals.

Alongside heat resistance, the project will evaluate biodegradation in different environments and carry out safety assessments and practical food-packaging tests. The research aims to balance functionality, sustainability and cost, providing more material options for foodservice packaging.

BORN runs from October 2025 to September 2028 and remains in the research and development phase. Its performance and application targets require further validation.
