Abstract

The invention relates to the field of disposable tableware, and aims to provide fully-degradable disposable vegetable fiber tableware which is capable of realizing full degradation. The fully-degradable disposable vegetable fiber tableware is prepared by mixing and pressing the following components in parts by weight: 65-80 parts of vegetable fibers, 6-8 parts of polyvinyl alcohol, 0.5-1.0 part of edible pigment, 1-2 parts of polyethylene wax, 1-2 parts of glycerol, 1-2 parts of sodium bicarbonate, 1-2 parts of edible gelatine, 1-2 parts of terpene resin and 1-2.5 parts of shellac.

Description

technical field [0001] The invention relates to the field of disposable tableware, in particular to a fully degradable disposable vegetable fiber tableware. Background technique [0002] Disposable plant fiber degradable tableware is a disposable degradable tableware produced by dry method using agricultural waste (such as wheat straw, rice straw, peanut shell, etc.) as the main raw material. The product does not produce waste water and pollution during the production process. It can be partially degraded after returning to the soil, and can be used as organic fertilizer after returning to the soil. The waste after processing crops is used as raw material to make degradable disposable tableware to replace foamed plastic tableware. The whole production process of this project is pollution-free, which is in line with the comprehensive recycling of resources. , but also conducive to the protection of the ecological environment. [0003] Chinese Patent No. 201110210113.0 disclo...
