Abstract

The invention discloses a disposable degradable paper cup, which includes a degradable paper cup body and an inner film coated on the inner surface of the degradable paper cup. The degradable paper cup body includes the following raw materials: cassava starch, sisal Fiber, flax fiber, alginate fiber, peach gum, trehalose, pullulan, polyvinyl alcohol, methylcellulose, carrot, onion, cabbage, licorice, ebony plum, citrus peel, gardenia, magnolia officinalis; described The inner membrane includes the following raw materials: polyhydroxyalkanoate, lotus leaf powder, locust bean gum, protamine and mustard seed powder. The invention also provides a method for preparing disposable degradable paper cups. The disposable degradable paper cup of the present invention can effectively improve the degradability of the paper cup.

Description

technical field [0001] The invention relates to a paper cup, more specifically, the invention relates to a disposable degradable paper cup and a preparation method thereof. Background technique [0002] Disposable paper cups are an indispensable product in people's daily life, especially in the catering industry, where the usage of disposable paper cups is very large, but many disposable paper cups currently used are non-degradable and easy to cause environmental pollution. [0003] With the modern society's higher and higher requirements for the living environment, more and more people pay attention to the urban greening work. The development of disposable degradable paper cups is an effective way to solve plastic pollution. Among them, biodegradable materials with natural macromolecules have simple processing equipment, and the degradation products are non-toxic and pollution-free, so they have the most development prospects. The existing biodegradable materials of natura...
