Bio-based nanocrystals for recyclable high-barrier blister packaging
Introducing bio-based chitin nanocrystals to enhance recyclable blister packaging, providing superior oxygen and moisture barriers while maintaining recyclability. This solution aligns with APR/Recyclass guidelines and aims to replace multi-layered webs with a single-material approach.
Overview
The proposed solution centers around integrating bio-based chitin nanocrystals (NCs) as additives in recyclable blister packaging. This innovation aims to significantly enhance oxygen and moisture barrier properties while maintaining the packaging's recyclability. Designed to work with mono-material webs using resins such as PP, LDPE, and PET, both virgin and post-consumer recycled, this approach reduces contamination and adheres to APR and RecyClass guidelines. The use of single-material webs, as opposed to traditional multi-layered barriers, presents a sustainable alternative that minimizes environmental impact.
Technical specifications
- Material Compatibility: Works seamlessly with APR/RecyClass-aligned resins (PP, LDPE, PET).
- Barrier Enhancement: Enhances oxygen and moisture barriers at low additive loadings.
- Recyclability: Maintains compatibility with existing recycling systems, including aluminum-lid prototypes.
- Additive Benefits: Chitin NCs are non-toxic, cost-effective, and improve processability.
- Performance Metrics: Optimized for oxygen transmission rate (OTR) and water vapor transmission rate (WVTR) at various thicknesses.
- Future Enhancements: Potential integration of synergistic minor additives for ultra-high performance.
Technology readiness level
The development is currently at TRL 4, indicating that components have been validated in a lab environment. Future steps include optimizing additive loading, prototype validation, and regulatory compliance testing. Potential partnerships include sponsored research and co-development opportunities.
