Biodegradable and disposable straw article and preparation method thereof

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.

Description

technical field [0001] The invention relates to the technical field of catering utensils manufacturing, in particular to a biodegradable straw disposable product and a preparation method thereof. Background technique [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 product...

[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 Examination of Production Permits for Plastic Packaging, Containers, Tools and Other Products stipulates that raw and auxiliary materials for food must be used when producing plastic packaging products for food. However, in order to reduce costs, some enterprises use industrial-grade materials for production, and some enterprises Even recycled materials are used as raw materials for food packaging, and the above-mentioned "Detailed Rules" clearly stipulate that purchased recycled materials and contaminated raw materials must not be used

Recycled materials have a wide range of sources and complex components. Some may be medical waste, and some may have been in contact with some waste, which may bring new pollution during the circulation and recycling process; in the recycling process, some plasticizers will also be added Substances harmful to human health, such as agents and masking agents, increase the risk of migrating into food

In addition, in order to reduce production costs, some food packaging companies add a large amount of inorganic mineral fillers such as calcium carbonate and talcum powder, which will easily cause the evaporation residue of the product to exceed the standard. When containing acidic or fatty food, it is easy to precipitate and stick to the food. Consumers are prone to cholelithiasis and other problems after eating
