 The study aims to develop eco-friendly biodegradable films with improved properties using poly, vinyl alcohol, nano-coconut shell filler, PVA, NCSF, as potential substitutes for existing petroleum-based synthetic polymers. The biofilms were characterized by various techniques and the results showed that the addition of NCSF at 25-weight percent level enhanced the tensile strength and elastic modulus, while the percent of elongation linearly decreased with the incorporation of filler. The water absorption of PVA, NCSF biofilms slightly increased with increase in the NCSF content. Soil burial test results showed that 34% weight loss of biofilms due to NCSF loading in PVA matrix, confirming their potential for packaging applications. This article was authored by D.
