[0002] Traditional disposable tableware mainly refers to polystyrene tableware. Because it caters to the contemporary people's pursuit of fast, convenient and hygienic life requirements, and is low in cost, once it comes out, it is quickly applied and promoted all over the world. However, due to The refractory polystyrene has caused great pollution to the environment. With the rapid development of the economy and the enhancement of environmental protection awareness, the original popular, fast and convenient, non-degradable disposable polystyrene tableware has been approved by the relevant state. In addition, food plastic packaging materials are widely used due to their advantages of lightness, low price, waterproof, and easy to carry. China implements production license management for food plastic packaging materials, and the plastic materials that can be used for food packaging are mainly Polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyamide (PA), polycarbonate (PC), polystyrene (PS), polyvinyl chloride (PVC) ), polyvinylidene chloride (PVDC), etc., but due to the refractory degradation of polymers, it has caused great pollution to the environment. In recent years, the health and safety of plastic packaging for food has attracted more and more public attention. In China's "Food The Detailed Rules for the

Abstract

The invention relates to the technical field of tableware making, in particular to a biodegradable and disposable straw article and a preparation method thereof. The biodegradable and disposable straw article is prepared from the following raw materials: straw powder, starch, fiber, glycerol, bioplastics, a release agent, an accelerant and water. Waste plant straw is taken as a raw material, so the production cost is greatly lowered; the foamed disposable article is prepared by the assistance of multiple functional auxiliaries; after being heated, the disposable article cannot generate any toxic component, and can be converted into easy-to-degrade matter under a natural condition, and the degraded matter further can be recycled and reused, thus achieving environment ideas of safety, environment friendliness and waste utilization, and effectively protecting environment.
