High demands and diverse applications of plastic materials had contributed immensely to the social-economic growth of the nations especially in the packaging industry. However, plastics have been a major contributor to the world's present garbage problems especially from the packaging sector of the industry. The menace was traced to non-degradable characteristics of LDPE and HDPP resins often used in the productions, hence, the need for biodegradable polymer blends.;l Co-polymer from Cassava (Manihort Species) starch with glycerol, vinegar and water was formulated to produce slurry, which was heated to about 1000c to form gel, dried to about 12% moisture. The resulting chips were  weighed in the ratios of 1:0, 1:3, 1:1, 3:1, 0:1 (wt/wt %)  to pure low density polyethylene (LDPE) resins. Each formulation of mixture was extruded at 1600C to produce polymer blends (plastics) in batches. The samples were chipped into same dimensions of 2.0mm thickness, 15.00mm width and 30.00mm and characterized. The mechanical properties of the polymer blends were found to decrease as the Copolymer increased. The best Young modulus was achieved with pure LDPE extrudate having 0.45±0.005 (109N/m,Gpa) and the least in the pure copolymer 0.11±0.005 (109N/m,Gpa). The homogenous dope exhibited compatibility of cassava starch with polyethylene and it took up to 72 hr for each of the samples to cure completely.
