Abstract


The biodegradable plastics (BGP) were fabricated from the blend of jackfruit seed powder starch and poly(vinyl alcohol) (PVA). Development of BGP is highly recommended and getting extensive interest to develop an environmentally friendly material that can replace the petro-chemical plastics. The aim of this research is to fabricate the BGP from the jackfruit seeds/PVA blend and characterize the mechanical and biodegradability properties. Results on the mechanical properties of the fabricated BGP shows that by increasing the composition of jackfruit seed powder starch, the tensile strength of the BGP was significantly decreased. The biodegradability properties of the samples were determined by monitoring the structure of fabricated BGP by using Fourier Transform Infrared Spectroscopy (FT-IR). The FT-IR results indicated that the structural properties were changed after 8 weeks of soil burial test by comparing with control samples. BGP with high amount of jackfruit seed powder starch shows better biodegradability characteristics.
