Preparation of Starch-Based Biodegradable Film and the Application in Agriculture

Lei Xu, Xizhi Jiang, Yongfu Zhao, Liru Xia


A starch-based biodegradable film was prepared in this paper, and the properties of the film were discussed. The film was prepared with polyethylene grafted and blended by epichlorohydrin modified-corn starch, linear low density polyethylene, low density polyethylene and maleic anhydride. Epoxy soybean oil was served as plasticizer and a small amout of ethylene propylene diene monomer was used as compatibilizer. 0.012 mm thickness degradable films were prepared with various blow molding methods. FTIR was used to characterize the modified starch and SEM was used to observe the morphology of the film before and after the modification. The results showed that the film could maintain an excellent performance on mechanical properties and degradation until the content of modified starch increased to 70% and have a good future in agricultural application.
