Environment-friendly biodegradable food packaging box

Abstract

The invention discloses an environment-friendly biodegradable food packaging box. The food packaging box is prepared from, by weight, 30-45 parts of sweet potato starch, 8-12 parts of hydroxypropyl methyl cellulose, 1-2 parts of a plant fiber modifier, 3-8 parts of an antibacterial solvent, 4-6 parts of polyethylene glycol, 1-2 parts of an emulsion adhesive, 0.05-0.1 part of cellulase, 1-3 parts of polyol, 6-8 parts of chitosan and 6-8 parts of a composite filler. The sweet potato starch, the hydroxypropyl methyl cellulose, the plant fiber modifier, the antibacterial solvent, the polyethyleneglycol, the emulsion adhesive, the cellulase, the polyol, the chitosan and the composite filler are matched; the food packaging box is prepared through the procedures of mixing, stirring, drying, extrusion forming and the like, the needed technological process is simple, manufacturing materials of the packaging box are all degradable materials, after the food packaging box is used up, unmanned treatment is conducted in time, the food packaging box can be slowly degraded, harm of the food packaging box to the nature is reduced, and the food packaging box belongs to an environment-friendly biodegradable packaging box.

Description

technical field [0001] The invention belongs to the technical field of food packaging, and in particular relates to an environment-friendly biodegradable food packaging box. Background technique [0002] Food packaging is an integral part of food commodities. One of the main projects in the food industry process. It protects the food and prevents the damage of biological, chemical and physical external factors during the circulation of the food from the factory to the consumer. It can also have the function of maintaining the stable quality of the food itself. It is convenient for the consumption of food. It is also the image that first expresses the appearance of food and attracts consumption, and has value other than material cost. Therefore, food packaging process is also an inseparable part of food manufacturing system engineering. However, the versatility of the food packaging process makes it have a relatively independent self-system. [0003] Food packaging can be...

Problems solved by technology

[0004] Food packaging boxes are currently one of the most widely used packaging products. However, after people discard food packaging boxes, they will sink into Underground, it takes a long time to complete natural degradation. In the process of degradation, it will cause harm to the soil and environment around the packaging box, which is not conducive to the protection of the environment. Therefore, an environmentally friendly biodegradable food packaging is proposed. box
