1. The process of making a degradable starch-based resin comprising:
- peeling a starch-based plant feed stock selected from one or more Sago plants;
extracting a quantity of starch content from the peeled starch-based feed stock;
drying at least a portion of the quantity of starch content by substantially removing the water content from the starch content resulting in a base material in the form of a dried starch polymer;
processing the base material in a reactor into a quantity of soft starch polymer;
subsequent to the processing step, further polymerizing the soft starch polymer by combining and reacting in a reactive-extruder with maleic anhydride, a polyethylene-based plastic resin, a quantity of glycerol, and an oil to define a further polymerized starch, and;
partially cross-linking the further polymerized starch with the polyethylene-based plastic resin to form the degradable starch-based resin.

Abstract
A process for making a starch-based resin from a starch-based plant feed stock generally comprising the steps of extracting starch content from prepared feed stock, preparing a dried starch from the extracted starch content that may be polymerized in a reactor with a catalytic material, a petroleum-based plastic resin, a quantity of glycerol, and an oil which is high in free hydrogen, and partially cross-linking the polymerized starch with a petroleum-based plastic resin to form a starch-based resin that may be used to produce starch-based film and bag products and other articles of manufacture that have unique degradation properties is disclosed herein.
