High-stiffness and difficult-to-break degradable environment-friendly lunch box and preparation method thereof

Abstract

The invention relates to the technical field of lunch box processing, in particular to a high-stiffness and difficult-to-break degradable environment-friendly lunch box and a preparation method thereof. The lunch box comprises a lunch box body, wherein the lunch box body is integrally formed in a high-temperature mold pressing mode, the lunch box body comprises a box body, a plurality of reinforcing strips are integrally formed on the outer side wall of the box body at equal intervals, a plurality of separation grooves are regularly formed in the middle of the box body, a plurality of supporting plates are arranged on the inner sides of the concave surfaces of the separation grooves at equal intervals, an upper edge ring is arranged on the outer side of the top surface of the box body, anda supporting ring is arranged on the bottom surface of the box body. According to the design, the overall stability of the lunch box can be improved, the stiffness of the lunch box is improved, meanwhile, the anti-scalding performance of the lunch box can be enhanced, and better using experiences are brought to a user; and according to the design, the influence of plant fiber pigments on the color of a finished product can be reduced, meanwhile, the use amount of starch and plastic can be reduced, the using cost is reduced, the degradation period is shortened, the degradation rate is improved, and pollution of the disposable lunch box to the environment is relieved.

Description

technical field [0001] The invention relates to the technical field of lunch box processing, in particular to a degradable and environmentally friendly lunch box with high stiffness and no breakage and a preparation method thereof. Background technique [0002] With the continuous acceleration of people's pace of life, the utilization rate of disposable lunch boxes is getting higher and higher. At present, most common disposable lunch boxes are made of paper or plastic. Paper lunch boxes are non-toxic and harmless, and easy to recycle, but they consume a lot of natural resources and do not meet the development requirements of our country. The biggest problem with plastic products is that they are difficult to degrade, which will bring greater pollution pressure to the environment. The degradable plastics that are currently being promoted also have many problems, such as long degradation cycles, insufficient degradation, and high production costs. In addition, the existing...

Paper lunch boxes are non-toxic and harmless, and easy to recycle, but they consume a lot of natural resources and do not meet the development requirements of our country

The biggest problem with plastic products is that they are difficult to degrade, which will bring greater pollution pressure to the environment.

The degradable plastics that are currently being promoted also have many problems, such as long degradation cycles, insufficient degradation, and high production costs.

In addition, the existing disposable lunch box, because of its light and thin material, reduces the stiffness, is very prone to bending and damage, and is easy to burn people or objects.
