Thermoplastic starch resin and application thereof in food packaging material

The invention discloses a thermoplastic starch resin and an application thereof in a food packaging material, wherein the thermoplastic starch resin is obtained by putting raw materials such as modified starch, polylactic acid, protein polyamide, glycerol monomercaptoacetate and tri-2-ethylhexanoic glyceride into a twin-screw extruder for extrusion and granulation. According to the technical scheme, the thermoplastic starch resin which is easy to degrade and high in strength is obtained. 本发明公开了一种热塑性淀粉树脂及其在食品包装材料中的应用，将改性淀粉、聚乳酸、蛋白聚酰胺、甘油单巯基乙酸酯、三异辛酸甘油酯等原料投入到双螺杆挤出机中挤出造粒得到所述热塑性淀粉树脂，由本发明的技术方案获得了一种易降解、高强度的热塑性淀粉树脂。
