| Abstract: | After ban on single-use plastics, there is a great demand on biodegradable, green and sustainable bio-resin coating to replace the plastics liners for hydrophobic and moisture resistant paper-based packaging. The present invention intends to disclose the process for synthesis of bio-resin starting from epoxides of castor oil and development of coating on cellulosic paper substrate through condensation. The coating is suitable for fatty food and beverages filling and storage. The present invention also disclosed the biodegradability of the coated papers as well as the removal of the coating for reusability of the papers after consumption. The adopted process involves use of green starting material, industrially viable and cost-effective. |
