Acetamide was incorporated into cornstarch in the presence of sodium hydroxide in a solvent or aqueous medium separately. Thereupon, modified cornstarch was crosslinked with N-hydroxymethyl acrylamide to develop an insoluble bioplastic coating. Furthermore, a hydrophobic agent (AKD, Zein, PDMS) was added to the bioplastic coating to ensure water/oil repellency. The bioplastic-based coating was applied to paper-based packaging materials for characterization of physical properties such as strength, dynamic contact angle, moisture and oxygen barrier, grease resistance, repulping and biodegradability. Our lab test results show significant hydrophobicity, high moisture and oil resistance, and high strength in comparison to polyethylene-based commercial coated paper (commercial cup, plate). The biodegradability of our developed bioplastic coated paper was found to be about 96%.
