High barrier nanocoatings for compostable food packaging
Advanced nanocoating technology offering exceptional moisture and oxygen barriers for food packaging with compostable and FDA-approved materials.
Overview
This innovative nanocoating technology is designed to provide high barrier properties for food packaging applications. It is capable of achieving a water vapor transmission rate (WVTR) of approximately 1 g/m²/day and an oxygen transmission rate (OTR) of about 0.01 cc/m²/day under specified conditions. The nanocoatings are composed of two FDA-approved ingredients, ensuring safety and compliance for food contact applications. Additionally, the materials used are compostable, contributing to sustainable packaging solutions.
Technical specifications
Key features:
- Achieves low WVTR of ~1 g/m²/day at 27°C and 80% RH
- Achieves low OTR of ~0.01 cc/m²/day at 23°C and 0% RH
- Composed of two FDA-approved and compostable ingredients
- Demonstrated scalability from lab-scale to industry-scale coating lines
Technology readiness level
This technology is currently at a Technology Readiness Level of 6, indicating that it has been validated in a relevant environment and trialed on a large-scale coating line in the industry. Further collaboration with industry experts is sought to optimize performance and processing.
