Abstract

The invention relates to the technical field of food packaging, in particular to an antibacterial environment-friendly food packaging box and a preparation process thereof. The antibacterial environment-friendly food packaging box is prepared from the following raw materials in parts by weight: 45 to 65 parts of polypropylene, 20 to 30 parts of cassava starch, 5 to 10 parts of pentaerythritol stearate, 3 to 8 parts of a coupling agent, 2 to 5 parts of an antioxidant and 3 to 7 parts of an antibacterial agent. According to the preparation process of the antibacterial and environment-friendly food packaging box, the cassava starch is added into the raw materials to replace polypropylene, so that the production cost is reduced, the degradation of the food packaging box is accelerated, the environmental pollution is reduced, and the green and environment-friendly targets are achieved; functional nano zinc oxide is adopted as an antibacterial agent, the antibacterial performance of the food packaging box can be effectively improved, food pollution is reduced, and the shelf life of food is prolonged.

Description

technical field [0001] The invention belongs to the technical field of food packaging, and in particular relates to an antibacterial and environment-friendly food packaging box and a preparation process thereof. Background technique [0002] Food packaging refers to the general term for containers, materials and auxiliary materials used in food circulation to protect products, facilitate storage and transportation, and promote sales. Food packaging can protect the appearance and quality of food. Selecting appropriate food packaging materials can prolong the shelf life of food, prevent food from being contaminated by microorganisms, help improve the circulation value of food and the competitiveness of food brands, and expand the sales of food itself . With the improvement of my country's economic level, the food packaging industry has developed rapidly. Among them, box packaging technology is the most widely used. Most of the development of food packaging technology is based...
