Hierarchically reinforced biopolymers for sustainable packaging

Overview

The proposed solution introduces advanced biopolymer composite films for sustainable packaging, utilizing Soft Dendritic Colloids (SDCs) for enhanced performance. These films, composed of widely available natural biopolymers such as agarose and chitosan, offer a sustainable alternative to traditional packaging materials. The innovations include thermoformable and thermosealable biocomposite films that promise to reduce environmental impact significantly.

Technical specifications

• Biopolymer composition: Films are made from agarose and chitosan, reinforced with Soft Dendritic Colloids.
• Performance attributes: Enhanced mechanical resiliency, reduced permeability to water and oxygen, and the ability to be thermoformed and thermosealed.
• Innovation features: Incorporation of multilayer films with hydrophobic components for improved barrier properties.
• Production scalability: Plans for scaled-up fabrication techniques using paper fabrication lines.

Technology readiness level

The technology is at TRL 4, indicating that it has been validated in a laboratory environment. Future developments will focus on testing and optimizing packaging films on paper substrates, densifying films, and improving mechanical and barrier properties.
