The objective of this investigation is the study and characterisation of chitosan/lactic acid based polyester blend films which are used as bio-packaging material for potential food applications. The first part of the investigation was related to the synthesis of Poly (hexane diol lactate-co-hexane diol sebacate) polyester, PHLSe by melt polycondensation method. The synthesised polyesters were characterised by FTIR, 1H NMR, 13C NMR and DSC analysis. Biodegradable blend films based on chitosan with synthesised polyester (PHLSe) was prepared using acetic acid-acetone solvent system by solution mixing and film casting method. This blend film was also investigated for its miscibility using FTIR spectra. FTIR spectra showed the changes in the finger print region of the chitosan amide band in the blend, indicating compatibility between hydrophobic chitosan with synthesised polyester. Morphologies of these blend films were viewed using Scanning electron microscopy. The chitosan/polymer blend film was used to study antifungal activity on three fungal strains. © 2015, Sphinx Knowledge House. All right reserved.
