The present invention discloses a method of making a non-biodegradable flexible packaging substrate biodegradable. The method comprises the steps of (i) providing a substrate web from an unwind to a coating station (402), (ii) applying thin layer of uniform deposition of a curable coating on atleast one surface of the substrate partially or completely by the coating station wherein the external surface of the substrate is essentially coated, (iii) curing the coating applied on the substrate web by a curing unit, and (iv) collecting the coated substrate web in roll at rewind. Further, the thickness of the thin layer of uniform deposition is in the range of 0.01 gsm to 10 gsm. Representative drawing

The present invention describes tunable methods of treating cellulosic materials with a barrier coating comprising a prolamine and at least one polyol fatty acid ester that provides increased oil and/or grease resistance to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for adhering of the barrier coating on articles including articles comprising cellulosic materials and articles made by such methods. The materials thus treated display higher lipophobicity and may be used in any application where such features are desired.
