Pfas-free soy protein–nanocellulose barrier platform for fiber foodservice packaging
PFAS-free barrier technology using soy protein reinforced with nanocellulose for fiber foodservice packaging. Designed as a coating or treatment for paper and molded fiber to improve water, grease, and thermal resistance while reducing reliance on plastic coatings. Formulations may include mineral or naturally derived modifiers and target sustainability outcomes such as repulpability or compostability.
Overview
The soy protein–nanocellulose barrier platform provides a PFAS-free alternative to conventional petroleum-based plastic coatings for foodservice packaging. The technology uses soy protein isolate reinforced with cellulose nanofibrils or cellulose nanocrystals to form a barrier system that enhances water resistance, grease resistance, and thermal durability. It is intended for application as a coating or treatment on paper and molded fiber substrates to improve the sustainability and performance of fiber-based packaging.
Technical specifications
- PFAS-free formulation: Uses soy protein isolate and cellulose nanofibrils/nanocrystals as primary components.
- Enhanced resistance: Improves water, grease, and thermal resistance of fiber-based packaging.
- Versatile application: Can be applied as a coating or treatment on various substrates, including paper and molded fiber.
- Optional modifiers: Incorporates mineral or naturally derived modifiers to optimize performance.
- Sustainability focus: Reduces dependence on petroleum-based materials, with potential end-of-life options such as repulpability or compostability.
Technology readiness level
The technology is currently at TRL 4, indicating it has been validated in a lab environment. Future steps include joint specification phases and substrate application trials to refine formulations for manufacturability and validate performance under real-world conditions.
