Abstract

The invention belongs to the technical field of packaging materials, and particularly relates to a degradable food packaging material and a preparation method thereof.The preparation method comprises the steps that raw materials are prepared, and the raw materials comprise polyvinyl alcohol, starch, commercial peach gum, gelatin, water, oosperm, chitin, polylactic acid and flax. The mass percentage of each component is as follows: the weight percentage of the polyvinyl alcohol is 30%, the weight percentage of the starch is 20%, the weight percentage of the commercial peach gum is 8%, the weight percentage of the gelatin is 12%, the weight percentage of the water is 8%, the weight percentage of the oosperm is 5%, the weight percentage of the chitin is 8%, the weight percentage of the polylactic acid is 4%, and the weight percentage of the flax is 5%. According to the degradable food packaging material and the preparation method thereof, by arranging the flax, the chitin and the commercial peach gum, the performance of friction resistance, high temperature resistance, nonflammability and uneasiness in cracking of the flax is achieved, the overall toughness and mechanical strength of the food packaging material are improved, and then the quality of the food packaging material is guaranteed.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a degradable food packaging material and a preparation method thereof. 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] Existing food p...
