A method for continuous preparation of a starch-based biodegradable polymer. A homogeneous mixture of starch, an ethylene acrylic acid co-polymer, and a salt of stearic acid are premixed before addition of an aqueous lubricant material. An increase in temperature gelatinizes the starch and melts the co-polymer. Excess moisture is removed under reduced pressure and a plastic material is extruded.
