Chitin nanocrystal-enhanced barrier packaging for cellulose-based solutions
Neptune Nanotechnologies offers chitin nanocrystal (CNC) additives, derived from crustacean waste, to enhance cellulose packaging by improving barrier properties and mechanical strength. This eco-friendly solution is recyclable, biodegradable, and scalable.
Overview
Neptune Nanotechnologies has developed an innovative approach to enhancing cellulose-based packaging using chitin nanocrystal (CNC) additives derived from crustacean shell waste. These CNCs enhance the oxygen and moisture barrier properties of packaging materials while maintaining recyclability and environmental sustainability. CNCs are biodegradable and offer a cost-effective alternative to traditional polymer-based additives, making them ideal for sustainable packaging solutions.
Technical specifications
CNCs integrate seamlessly with cellulose materials, either as a coating or as a bulk-incorporated additive. Key benefits include:
- Barrier Enhancement: CNCs improve water resistance by tenfold and reduce oxygen transmission rates by 133%.
- Mechanical Strength: They increase tensile strength by 67%, bending strength by 2.5 times, and impact resistance by 65%.
- Environmental Impact: The proprietary process minimizes water and solvent use, reduces methane and carbon emissions, and reuses by-products.
- Application Flexibility: CNCs can be applied through spray-coating or wet-end integration, suitable for Kraft paper, food trays, and more.
Technology readiness level
Currently, at Technology Readiness Level 5, this technology has been validated through pilot tests showing clear functional benefits. Future validation will focus on optimizing formulations and conducting pilot-scale trials to ensure manufacturing compatibility and recyclability.
About Neptune Nanotechnologies Inc.
Neptune Nanotechnologies Inc. is a bio-nanotechnology startup that specializes in converting organic fishing waste, such as crustacean shells, into high-value chitin nanocrystals. This proprietary technology extracts the naturally occurring chitin—a material known for its strength, light weight, and biodegradability—to create a sustainable, bio-based additive. By integrating these nanocrystals into various materials, the company aims to enhance performance characteristics such as strength, stiffness, and durability, while simultaneously offering a greener, non-toxic alternative to synthetic and petroleum-based chemical additives.
The company serves diverse industries, including aerospace, automotive, biomedical, packaging, and additive manufacturing, by helping them achieve sustainability goals without sacrificing functional requirements. Neptune works to displace hazardous materials and reduce the environmental footprint of finished goods, such as improving the moisture resistance and strength of paper-based packaging. Supported by various commercialization programs and strategic investors, the company is actively moving its technology from research and development into real-world pilot testing and market applications to provide renewable solutions for a circular economy.
