Pfas-free graphene oxide coating for sustainable paper packaging
A novel, environmentally friendly coating derived from graphene oxide offers a non-toxic, water- and oil-resistant alternative to traditional plastics and PFAS in food packaging. Developed by Northwestern University, it enhances strength, recyclability, and compostability, supporting sustainable packaging solutions.
Overview
Researchers at Northwestern University have developed a PFAS-free coating based on graphene oxide that provides water- and oil-resistant properties for paper packaging. This innovative material addresses environmental and health concerns associated with traditional plastics and toxic PFAS, offering a safer, sustainable alternative for the food industry. The coating is non-toxic, environmentally friendly, and enhances the strength and barrier properties of paper-based packaging, making it suitable for various food and beverage applications.
Technical specifications
Key features:
- Derived from graphene oxide, a non-toxic nanomaterial
- Provides water and oil resistance
- Significantly improves the strength and barrier properties of paper packaging
- Recyclable and compostable after use
- Cost-effective and scalable for commercial production The coating is being commercialized through GO-Eco, a startup affiliated with Northwestern University, which is working to bring this sustainable solution to market.
Technology readiness level
This technology is currently in development and has demonstrated promising results in third-party evaluations, outperforming existing solutions in strength and barrier performance. It is moving toward commercial deployment, with ongoing efforts to scale production and adoption in the food packaging industry.
