With the economic development, people's living standards have been continuously improved, which has stimulated the development of the food industry. As a fast-food industry, the development of the food industry has led to the development of the packaging industry. Under the influence of environmental awareness, the food packaging and packaging industry is developing in a green direction. Recently, Beijing was the first to use recycled PET raw materials as food packaging. Food packaging is an integral part of food products. One of the major projects in the food industry process. It protects foods, prevents them from being damaged by biological, chemical and physical external factors during the process of leaving the factory and the hands of consumers. It can also have the function of maintaining the stable quality of the food itself. It facilitates the consumption of food. It is also an image that first expresses the appearance of food and attracts consumption, and has a value other than material costs. Therefore, food packaging process is also an integral part of food manufacturing system engineering. Packaging plays an important role in the healthy development of the food industry. In the development of eco-economy to become a global common demand, many developed countries have developed PET packaging recycling technology, as early as in 1991 has been recycled PET slices for food packaging. Zhao Yan, the person in charge of Yingchuang Company, told this reporter that the production line of Yingchuang's PET raw material - PET bottle product - post-consumer waste bottle - recycled bottle grade PET material - PET bottle product can recycle 50,000 tons of discarded PET bottle every year It reached 40% of the total amount of waste PET bottles in Beijing and produced 25,000 tons of materials that can be used to regenerate PET bottles. Our country has also begun to join this army. Beijing will take the lead in using the recycled PET raw materials as food packaging in China. At present in China, all PET bottles are made from raw PET raw materials refined from petroleum. China's first renewable food grade PET chip production company, Yingchuang Renewable Resources Co., Ltd. realized PET bottle products made from raw PET materials, to recycling waste bottles to make recycled PET bottle grade slices, and used for closed-loop feedback recycling of PET bottle products. The model of reuse has reached the standards reviewed by the Ministry of Health and the State Administration of Quality Supervision, Inspection and Quarantine. The recycled PET chips are food-grade standards that can be used to produce food packaging.
