Nano-cellulose coating for enhanced gas-volatile compound barrier on polyethylene films

Overview

This innovative solution involves the application of a nano-cellulose coating on polyethylene films to significantly reduce the permeability of volatile organic compounds (VOCs) and gases. By enhancing the barrier properties of standard polyethylene films, this technology offers advanced packaging solutions, particularly beneficial for industries requiring stringent control of gas and VOC emissions such as food and pharmaceuticals.

Technical specifications

Key features:

• Nano-cellulose coating: Utilizes specially produced nanoparticles to create a barrier layer on polyethylene films.
• Reduced permeability: Demonstrates improved resistance to VOCs and gases, measured via chromatography and permeabilimeters.
• Raw material selection and nanoparticle production: Requires homogenizers, pH meters, chemical reagents, distilled water, and reactors for suspension preparation.
• Coating process: Capable of being applied at both laboratory and industrial scales, facilitating broad adoption and scalability.

Technology readiness level

This technology is currently at Technology Readiness Level 3, indicating active research and development. It requires further validation and testing, including migration tests and coating characterization. Potential collaborations with research institutes and universities are sought for further development and validation steps.
