Food packaging is an integral part of food products. One of the major projects in the food industry process. It protects food, prevents the damage of biological, chemical and physical external factors during the circulation of food from the factory to the consumer. It can also have the function of maintaining the stable quality of the food itself, which is convenient for food consumption. 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 processes are also an integral part of food manufacturing systems engineering. But the versatility of the food packaging process makes it a relatively independent self-system.
