Process for processing degradable tableware from grass fibres

Abstract

The invention relates to a process for processing degradable tableware from grass fibres. The process comprises the following steps of: 1), selecting and processing raw materials, namely taking grass fibre plants and removing various non-cellulosic impurities from the plants to separate relatively pure cellulose out; 2), pressing the cellulose to mould the cellulose; and 3), coating a film, wherein the thin film is formed by spraying and drying biologically degradable polymer solution. In the product provided by the invention, the special material characteristic of the natural grass fibre plants and a biological binder are adopted. After the product is moulded, physical indexes, such as heat resistance, pressure resistance, tensile strength and the like, are better than those of the traditional products sold in market. The raw materials of the product are natural plants; the production process is sterilized at a high temperature; after being used, the product is easy to dissolve in water and no residue is left; the product can serve as a fodder; and after being buried in soil for 3 months, the product is naturally degraded into an organic fertilizer. Through the study, the beneficial effects of natural degradation, no toxicity and harm, environment friendliness and resource conservation are achieved.

Description

technical field [0001] The invention relates to a process for processing degradable tableware with grass fibers. Background technique [0002] At present, some environmentally friendly lunch boxes used in the market have serious quality problems (the evaporation residue exceeds the standard). The added minerals and additives dissolve with the water, vinegar, oil, etc. contained in the food, and as the food people eat enters the human body, it causes various diseases such as indigestion, local pain, and liver system lesions. Severe cases can lead to gallstones and heavy metal poisoning, which have a serious impact on children's intellectual development. According to a survey by the International Food Packaging Association, nearly 80% of biodegradable tableware on the market are fakes. [0003] Environmentally friendly tableware is made of materials that are harmless to the human body, non-toxic, tasteless, and easy to degrade. There is no pollution in the process of manufac...

Problems solved by technology

However, ten years have passed. Based on factors such as market supply, consumer awareness, and cost, "fake degradable" products are prevalent in the industry. At the same time, the safety performance of "degradable tableware" is poor, and it is easy to mold and rot during storage.
