Food packaging is an integral part of food products. One of the main engineering processes in the food industry. It protects food and prevents damage from biological, chemical, and physical external factors during the circulation process from leaving the factory to consumers. It also has the function of maintaining the stable quality of the food itself. It facilitates the consumption of food and first displays the appearance of the food, attracting consumption, and has value beyond material costs. Therefore, the food packaging process is also an integral part of food manufacturing system engineering. But the universality of the food packaging process also gives it a relatively independent self system.
