High Barrier, Biodegradable Nanocomposite Films Based on Clay‐Coated and Chemically Modified Gum Kondagogu

Lately, environmentally benign packaging materials with biodegradability, flexibility, and high barrier properties are sought after as a substitute for conventional plastic due to increasing pollution microplastics in the environment. Although natural polymers can be sustainable alternatives petro-sourced, non-biodegradable plastics, they suffer from poor mechanical properties. In this study, mechanically stable, biodegradable film of tree gum kondagogu remarkable is fabricated. The introduction spray-coated, waterborne, large-aspect ratio sodium-hectorite dispersion on tree-gum films ensured very even at relative humidity conditions (oxygen transmission rate (OTR) ≈1.7 cm3 m−2 day−1 bar−1 75% humidity). coating not only decreases gas permeability through but also minimizes sensitivity performance levels. clay-coated nanocomposite outperformed various commercial comparable high-performance terms oxygen Further, improved rendering them prospective material. These biodegradable, high-barrier robust promising advance field packaging.
