Abstract
Plastic is an unavoidable packaging, handling and coating material for food, medical and agricultural industries as well as agricultural farm. This plastic are made from synthetic polymers. These polymers are objectionable for environment. There is direct need to have option of these synthetic polymers. Many researches on natural polymers were carried out. These natural polymers may be protein, starch, polysaccharides etc. 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.
