Abstract

The invention discloses a preparation method of an antibacterial and oil-proof packaging carton, which comprises the following steps: S1, preparation of an antibacterial and oil-proof base solution, S2, preparation of an antibacterial and oil-proof agent, S3, coating of an antibacterial and oil-proof layer, S4, drying and curing, and S5, preparation of the carton, the antibacterial and oil-proof packaging carton is prepared from a nontoxic and harmless degradable material, and the antibacterial and oil-proof packaging carton is environmentally friendly and safe. Chitosan used in the oil-proof food packaging paper has the characteristic of better inhibiting bacterial activity and can inhibit growth and reproduction of some fungi, bacteria or viruses, a certain amount of chitosan is added when the oil-proof food packaging paper is prepared, so that the packaging paper has a certain antibacterial property, cinnamyl alcohol in the components also has the characteristics of being natural, harmless, high in antibacterial property and broad-spectrum in antibacterial property, and the oil-proof food packaging paper has a good application prospect. Starch has the oil-proof characteristic and has a good protection effect on the packaging carton and food wrapped by the packaging carton.

Description

technical field [0001] The invention relates to the technical field of packaging products, in particular to a preparation method of an antibacterial and oil-proof packaging carton. Background technique [0002] Due to the influence of microorganisms, enzymes, oxygen and other factors, the quality of food will change to varying degrees during storage, thereby reducing its edible and commercial value. These changes can lead to a reduction in the shelf life of foods and increase people's risk of contracting foodborne illnesses. For paper-packaged food, the food and the wrapping paper are basically in direct contact, and the storage environment of some foods is relatively humid and cold, which provides living conditions for the growth of bacteria. For ordinary food wrapping paper, it cannot provide microbial protection for various foods. In addition, today, with the rapid development and diversification of food types, oily foods are more common, and the corresponding food pack...
