This paper reviewed for starch as natural polymer, chemical form of starch for conversion in plastic film, effect of amylose/amylopectin content, effect of lipid content and effect of relative humidity on properties of starch film. For strengthening of plastic film from starch, a blend with synthetic polymer is also discussed with limited synthetic polymers like polyethylene, polyester, polypropylene, and polylactic acid considering the length of review article. |
