Polymer scientists at IIT-Roorkee have claimed to have developed an indigenous technology to create "bio-based" packaging (colour) materials. They said with their technology, making counterfeit packaging of any product would be highly difficult.
A peer-reviewed scientific journal - ACS Applied Nano Materials - - has published its study in its recent issue. To fulfil their objective of a bio-based technology, researchers used bagasse (agro-waste sugarcane) and organic acids (As) like citric, malic and tartaric acids, etc, after extracting from orange, apple and tamarind.
