Ample biodegradable eggshell powder (ESP)/wheat protein isolate (WPI) composite films were made by solution casting method of altering the WPI solution and fused with ESP particles in the percentage of 5, 10, 20, 30, and 40% (w/w) and asses the properties, i.e., physical, mechanical, and thermal as a function of ESP concentration. Determine the unification of ESP particles into the WPI matrix by X-ray diffraction, fluorescence spectra, and SEM analysis. The data clearly showed the successful incorporation of ESP particles and good compatibility with the WPI and also mechanical properties and thermal stability of composite film increasing with the increasing ratio of ESP. Microstructural evaluation confirmed the aggregation and distribution of ESP particles within the WPI matrix and validated the results of functional properties of the WPI/ESP film. The results confirmed that the composite films have potential applications in the field of food and medicinal packaging especially for photosensitive medicines in a very simple and cheap way.
