Technical Field

The invention relates to the technical field of food packaging, in particular to an edible packaging material and a preparation method thereof.

Background

With the acceleration of the pace of life of people, social life is developing towards convenience and sanitation. In order to meet such demands, disposable foam lunch boxes, plastic bags, chopsticks, water cups, etc. have started to frequently enter people's daily lives. The appearance of the packaging materials with convenient use and low price brings great convenience to the life of people. On the other hand, these packaging materials are often discarded after use, causing "white pollution", creating environmental hazards, and posing a significant environmental problem. White Pollution (White Pollution) is an image name for the phenomenon of environmental Pollution caused by waste plastics, and refers to the Pollution to ecological environment and landscape caused by random and random throwing and difficult degradation treatment of plastic products such as packaging bags, agricultural mulching films, disposable tableware, plastic bottles and the like made of high-molecular compounds such as polystyrene, polypropylene, polyvinyl chloride and the like which are discarded into solid waste after being used.

White contaminated waste is usually disposed of in landfills or incinerated. A large amount of toxic gas is generated by burning to cause secondary pollution. The landfill occupies a large space, and the natural degradation of the white polluted garbage requires more than one hundred years, and additive can be separated out to pollute soil, underground water and the like. Therefore, the development trend of the white polluted garbage treatment technology is recycling, but the recycling and recycling rate of the white polluted garbage is low. The reason is that the problems in the aspects of living habits, management and recovery links exist, but more importantly, the recovery and utilization technology is not perfect.

The main sources of white pollution are food packaging, foam plastic filling packaging, snack boxes, agricultural mulching films and the like. Therefore, in the face of the increasingly severe environmental pollution problem, a feasible solution for eliminating the white pollution must be sought.

The edible package is a film material with the functions of packaging and fresh-keeping, which is prepared by using edible raw materials, such as mixing, heating, coating, drying and the like, and can be divided into a polysaccharide film, a protein film, a lipid film and a composite film of the polysaccharide film, the protein film and the lipid film according to the sources. The film with the porous network formed by the interaction between the different film matrixes can effectively protect the quality of food.
