The main aim of this research work is to prepare and characterize pectin based bio degradable, protective, proactive, active packaging blend films of low methoxy pectin and sodium alginate (75-25% w/w). Different blend films were prepared (75:25 P+SA, 100 P, 100 SA, 100+0.2% P+C, 75:25:/0.7% P+SA+C in this ratio. The antimicrobial activity of different blends tasted against food borne pathogen E. coli O157:H7 (MTCC 90), Salmonella typhii (MTCC 733) significance effect was showed for zone of inhibition. The free radical scavenging activity of 10% bio-composite incorporated cinnamaldehyde 0.30% blends based on linear correlation analysis (R2) which is 0.9235 for DPPH scavengers and citric acid was used as positive control. Statistically significance p<0.001 correlations were found between cinnamaldehyde significantly modified polymer tensile properties. The films were characterized by TGA, DSC, ATR-FTIR, XRD analysis results showed p<0.05 significant effect on thermal behavior of polymeric structures.
