Biopolymeric complex films for sustainable food packaging

Overview

Biopolymeric complex films present a groundbreaking approach to sustainable food packaging by utilizing natural polymers through an interpolymeric complex formation mechanism. This innovative method allows for the production of films with controllable thickness, strength, and physical properties. By incorporating essential oils and bioactives, these films enhance food preservation while being environmentally friendly and biodegradable.

Technical specifications

• Interpolymeric Complex Formation: Utilizes specific concentrations of polyelectrolytes to form a self-assembling matrix, processed into flexible films.
• Customization: Thickness and strength adjustable by varying biopolymer concentrations.
• Additives: Can incorporate essential oils, bioactives, and colorants for enhanced functionality and aesthetics.
• Material Properties: Non-dissolving, non-disintegrating, and non-swelling in aqueous environments.

Technology readiness level

Currently at Technology Readiness Level 3, these films have been developed as thin films on Teflon surfaces and show potential for further validation and commercialization in partnership with industry leaders for testing and refinement in real-world food packaging environments.
