Problems solved by technology

[0002] With the acceleration of people's life rhythm, the demand for disposable products is increasing, especially for lunch boxes and tableware. Disposable foam tableware is commonly used in the market now, which cannot be degraded after use, causing white pollution. , and degradable tableware has limited its scope of use due to high production costs; recently people have tried a variety of degradable tableware, but these degradable tableware have a certain degree of defects, the effect is not good, the degradation cycle is long, and In the process of use, often because the temperature of the freshly prepared meals is high, it is easy to be scalded when people touch the lunch box, causing inconvenience in use

Abstract

The invention belongs to the technical field of lunch-box preparation and particularly relates to a disposable lunch box with high strength and high degradation and a preparation method thereof. According to the preparation method, plant starch, gum tragacanth, polylactic acid, glycerin monostearate, vinyl-ethylene vinyl acetate copolymer, medical stone powder, a titanate coupling agent, an antioxidant 1010 and an antioxidant 1076 are used as materials, a reasonable proportion design is adopted, and process parameters are regulated, so that the lunch box is obtained. The disposable lunch box has the advantages that by mutual promotion of the materials, the physical properties such as wear resistance, pressure resistance and heat insulation of the lunch box are effectively improved, the degradation property also can be greatly improved and the degradation period is shortened.

Description

technical field [0001] The invention belongs to the technical field of lunch box preparation, in particular to a disposable lunch box with high strength and high degradation. Background technique [0002] With the acceleration of people's life rhythm, the demand for disposable products is increasing, especially for lunch boxes and tableware. Disposable foam tableware is commonly used in the market now, which cannot be degraded after use, causing white pollution. , and degradable tableware has limited its scope of use due to high production costs; recently people have tried a variety of degradable tableware, but these degradable tableware have a certain degree of defects, the effect is not good, the degradation cycle is long, and During use, often because the temperature of freshly prepared meals is relatively high, people are easily scalded when they touch the lunch box, causing inconvenience in use.
