With looming the global energy crisis and environmental problems Biodegradable green blends based on natural resources and biodegradable polymers have increasingly attracted many researches interest due to their advantages of low cost, use of renewable resource, and biodegradability. In this study, flaxseed mucilage (FM) was extracted with distilled water and utilised to make films with varying ratios of polyvinyl alcohol (PVA) and chitosan (Cs). Gamma irradiation was used as green method to improve the performance of the produced films. Then the films were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), UV–vis spectrophotometry and XRD analysis. The tensile measurements, moisture content were used to evaluate the films’ qualities. When flaxseed mucilage is mixed with PVA/Cs blend, it forms films that are less resistive, less rigid, and more flexible, improves mechanical properties and thermal stability. Films containing mucilage and PVA/Cs blend exhibited a compact and homogeneous structure under SEM, confirming the FTIR spectra that suggested a chemical interaction between these three biopolymers. Based on all above properties of the developed films, it can be envisaged to use these films for packaging applications.
