     Starch Plastic is a generic alternative new biodegradable plastic plastic. The preparation of a simple, low cost and easy to achieve the benefits. Starch plastics have excellent biodegradable, and easy way of oxygen and other advantages of composite materials, can be widely used in food, agriculture, textiles and health care industries.
This study used a single screw extrusion method of processing the starch plastic bar on a different formula of the plastic properties of starch. Key test of the plastic water-resistant starch and mechanical properties, and of the evolution of the starch plastics performance curve.
The results show that single-screw extrusion system, the samples from the manufacturer complete, rheological properties better. After modified the starch out of the thermoplastic starch plastic water resistance than pre-pre pared starch plastics better; considered, by adding cross-linking agent after the starch to improve the performance of water-resistant plastic, while the flow of starch plastics manufacturer Performance is basically remained stable.
Key words: thermoplastic starch; crosslinker; water-resistant properties; mechanical properties.
