Biodegradable packaging from bacterial cellulose films

Overview

Our solution focuses on producing high-performance biodegradable packaging utilizing bacterial nanocellulose (BNC) films derived from the bacterium Gluconacetobacter xylinus. This innovative material possesses outstanding tensile strength, crystallinity, and thermal stability, making it an ideal candidate for next-generation packaging solutions. By functionalizing BNC, we can improve its water resistance, antimicrobial properties, and oxygen barrier capabilities. This addresses the limitations of current cellulose-based packaging, offering a sustainable and compostable alternative suitable for food and pharmaceutical applications.

Technical specifications

BNC is a microbial polysaccharide composed of pure cellulose nanofibers, which are biodegradable and derived from sustainable sources like glucose and agricultural waste. Key features include:

• High tensile strength and crystallinity: BNC films offer superior durability compared to traditional cellulose materials.
• Thermal stability: Ensures performance under varying temperature conditions.
• Tunable barrier properties: Functionalization allows tailoring for specific needs, such as enhanced water, antimicrobial, and gas barrier functions.
• Sustainable production: Utilizes cost-efficient fermentation processes.

Technology readiness level

Currently at TRL 4, the technology has been validated in a lab setting. Future validation plans include optimizing BNC films for food packaging through batch fermentation process modifications and functionalization techniques. We will assess film morphology, crystallinity, and biodegradability under standard conditions, ensuring safety and performance compared to existing packaging solutions.
