Experimental Synthesis of TiO₂-WO3 Nanocomposite for Advanced PLA-Based Biodegradable Food Packaging Thin Films

The development and analysis of a biodegradable composite thin film based on TiO₂ PLA and WO3 for food packaging is depicted in this study. By introducing TiO₂ and WO3 nanoparticles into the PLA matrix engineers are able to elevate its strength and stability under heat while ensuring antimicrobial and UV shielding. Researchers examined several weight ratios of TiO₂-WO3 to ascertain the best mix for boosting the properties of the material. Mechanical analysis alongside thermal and optical testing was performed on the films. Research indicates that the incorporation of TiO₂ and WO3 nanoparticles greatly elevates the properties of PLA and establishes it as an ideal choice for green food packaging.
