Food packaging is an integral part of food products. One of the major projects in the food industry process. It protects the food, prevents the damage of biological, chemical and physical external factors during the circulation of the 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.

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.

The process of using plastic packaging food products mainly includes four industrial sectors: the first industry refers to the production of plastic resins and films. The second industry is the processing industry for flexible and rigid packaging materials, the third industry is the packaging mechanization production industry, and the fourth industry is the food processing industry. In the first industry, the use of petroleum, coal, natural gas and other raw materials, synthesis of polymerized low molecular compounds, and then into a variety of resins. This is processed into a single or multi-layer composite film for use in food processing plants.

There are many ways to classify food packaging.
