Effect of corn starch on LDPE and its suitability as food packaging film
Author(s): R Shah, G Immanuel and S Mathur
Abstract: This research work explores the possibility of incorporating corn starch to develop bio-plastics film using low density polyethylene (LDPE), glycerol, urea and talc powder. Corn starch incorporated LDPE film was made by twin screw extruder and blown film extrusion method with different proportion of corn starch T1 (5%), T2 (7.5%), and T3 (10%). The film was then tested for the physical, mechanical and other properties for its suitability in food packaging. The thickness of the film was found in the range of 0.7 mm to 1.3 mm. The tensile strength was found better for T2 (14.8 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 0.005% to 0.078%. This result was promising so that this biodegradable film can be used for food packaging and it will not deteriorate the environment. Bio-plastics can be easily manufactured in a larger scale if the required facilities are set up. 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.
