Abstract

The new insights in the development of biodegradable composites for packaging industries, using PVA (polyvinyl alcohol) and eggshell ash particles(ESAp) were investigated. The composites were produced using the modified solution cast method. In the experimentation; 0, 5, 10, 15, and 20wt% ESAp were used in the production of the composites. Tensile, Impact energy, Water absorption, Density, and Biodegradability tests were carried out on the resulting composites samples to determine their characteristics and composition with the most suitable property for mechanical and packaging applications. The composite samples showed variants in mechanical properties according to the results obtained from the tests carried out. This led to the conclusion that for optimum mechanical properties for packaging applications, bio-composites with the studied composition should be obtained at 15wt%ESAp. It was established that the developed composites film can be used in the packaging industries.
