AI Technical Summary

Technical Problem

Conventional sachets for liquid foods are made from persistent multi-material laminates that are hard to recycle and contribute to environmental waste, as they are not suitable for biodegradation and often end up in landfills or oceans.

Method used

Development of biodegradable flexible packaging with specific polymeric layers and inorganic barriers that can maintain product shelf life while minimizing environmental impact, by adjusting the water activity and content of the liquid food compositions to match the packaging's barrier properties.

Benefits of technology

The solution enables the marketing of liquid foods in biodegradable sachets that are less persistent in the environment, while maintaining a reasonable shelf life of 1-2 years, thus addressing the challenges of waste management and environmental sustainability.
