Nanocellulose-based coating for sustainable packaging solutions
A bio-based nanocellulose coating offering exceptional oxygen and grease barrier properties for packaging materials like cardboard. Validated through certified tests, this coating enhances sustainability by using degradable polymers.
Overview
The Fraunhofer Institute for Applied Polymer Research presents an innovative nanocellulose-based coating designed for sustainable packaging applications. This bio-based coating provides exceptional barrier properties, including low oxygen permeability and excellent grease resistance, making it ideal for use with packaging materials such as cardboard. Validated by the Nestle Purina test and other certified methods, this solution addresses the growing demand for environmentally friendly packaging options.
Technical specifications
- Bio-based polymers: Utilizes microfibrillated cellulose (MFC) and commercially available polysaccharide derivatives.
- Barrier properties: Offers very low oxygen permeability and acts as an effective grease barrier.
- Degradability: The coating is formulated to be environmentally friendly and degradable.
- Validation tests: Includes oxygen barrier, dynamic water vapour sorption, degradability, and redispersibility assessments.
- Application scale: Can be applied to packaging materials in a laboratory setting, with potential for larger scale production upon request.
Technology readiness level
This coating technology is at TRL 5, indicating that it has been validated in a relevant environment and is ready for further development and scaling.
