CHARACTERIZATION OF POLY LACTIC ACID (PLA) AND SODIUM ALGINATE POLYMERIC FILM

When combining PLA (polylactic acid) and sodium alginate in varying ratios, a range of biodegradable films can be created.These films can serve as environmentally friendly packaging materials in the food industry.Employing analytical techniques such as FTIR , XRD , SEM , and TGA allows for assessing the integrity and composition of the compound, measuring the film's thickness, exploring the material's resistance to temperature changes, and examining the external structure and texture of the film.use of Berries leaves extract with (PLA and Sodium alginate) for antibacterial properties.use of uv spectroscopy for combination of molecules in natural drug extraction.Antibacterial properties of drug loaded film are good for food packaging industries and a good biodegradable polymers.
