Thermoplastic starch is also called "non-structured starch", which can make the starch structure disordered and thermoplastic by certain methods. Starch molecules for polysaccharides molecular structure, containing a large number of hydroxyl, due to its intermolecular and intramolecular hydrogen bond action, so that its melting temperature is higher, and its decomposition temperature is lower than its melting temperature, so in the heat processing, starch molecules did not melt and first decomposed. The traditional mechanical processing method of plastic is mostly heat processing, so to make starch - based whole starch plastic needs to make natural starch thermoplastic. This thermoplasticity can be achieved by changing the crystalline structure inside starch molecules. Destroy intramolecular and intermolecular hydrogen bonds, disrupt the double helix crystal structure of starch molecules, which will reduce the melting temperature of starch and make it thermoplastic.
