    Abstract: This invention is a substantially completely biodegradable high starch polymer using completely biodegradable high polymer polyvinyl alcohol [PVOH] that is made to be compatible with starch. The two ingredients are mixed with the optional addition of elasticity enhancer and supplement agent to better the stability and durability of the products. During the mixing and heating process the starch molecular structures are randomized. The randomized starch molecules, the PVOH, the elasticity enhancer and the supplement then under go the process of co-polymerization. The mixture is then extruded, at a temperature that is above the crystallization temperature of the starch molecules, to form the first stage product, the pellets. The pellets can then be extruded into films using a traditional plastic film extruder.
