Effect of potato starch on LDPE and its suitability as food packaging film
Author(s): Kaushal Kumar and Genitha Immanuel
Abstract: This research work was done by incorporating potato starch to develop a biodegradable film using LDPE, glycerol, urea and talc powder. Potato starch incorporated LDPE film was made by blown film extrusion method with different proportions of potato starch T1 (5%), T2 (7.5%), and T3 (10%). Film was then tested for the mechanical and other properties for its suitability in food packaging. The thickness of the film was found in the range of 0.66mm to 1.25mm. The tensile strength was found better for T2 (13.02 MPa). Similarly dart impact resistance of the film was found to be in the range of 0.8 N to 1.2 N. Water absorption of the bio-based film increases from 0.030% to 0.066%. This result was promising so that this biodegradable film can be used for food packaging and it will not deteriorate the environment. The need for bio-plastics is now more than ever as the rate of plastic production and air pollution has increased at a rapid rate.
