A biodegradable and non-toxic water-soluble polymer is Polyvinyl Alcohol (PVA) is used in the present work. It is used in production industry applications because of its biocompatibility, low toxicity, and good adhesive properties. Biodegradable composite films are created in the current work using waste materials like wheat husk and coconut fibers. The alkali procedures are used to create the wheat husk (WH) powder. It is low cost and light-weight. Coconut fibers are eco-friendly and non-polluting too. Aloe-vera consists of properties such as adhesive properties, flexural strength, and good tensile strength. The solution-casting approach is used to create composite films with a polyvinyl alcohol basis. Films are given physical and mechanical descriptions. SEM (scanning electron microscopy), FTIR (Fourier Transform Infrared) spectroscopy, and DSC (differential scanning calorimeter) are used to study structural behaviours (DSC). Thermogravimetric analysis is used to evaluate the thermal stability of composite films (TGA). Mechanical properties such as tensile strength, % elongation, young modulus and surface properties have been evaluated. The non-destructive technique of X-Ray diffraction (XRD) is used to characterize crystalline materials. It provides detailed information about a material's crystallographic structure, chemical composition, & physical properties, including as structural parameters such as average grain size, crystallinity, strain, and crystal flaws, as well as crystal orientations (texture). Raman spectroscopy is a nondestructive chemical examination tool that can disclose a material's molecular interactions, chemical structure, phase, and polymorph. It is based on how light interacts with a substance's chemical connections.
