The environmental advantages of PET packaging are highlighted and promote the development of the food packaging industry

Food packaging is an integral part of food commodities , one of the main projects in the food industry process. It protects the food and prevents the damage of biological, chemical, and physical external factors when the food leaves the factory to the consumer. It can also have the function of maintaining the stable quality of the food itself. It is convenient for food consumption. It is also the first to show the appearance of food, attract the image of consumption, and have value other than material cost. Therefore, the food packaging process is also an inseparable part of the food manufacturing system engineering.

Packaging plays an important role in the healthy development of the food industry. Under the influence of environmental protection awareness, the food packaging and packaging industry is developing in a green direction. When the development of ecological economy has become a global common demand, many developed countries have developed PET packaging recycling technology. As early as 1991, recycled PET chips were used for food packaging.

Our country has also begun to join this army. It is understood that Beijing will take the lead in using recycled PET raw materials as food packaging in the country. At present in my country, all PET bottles are manufactured from virgin PET raw materials extracted from petroleum.

Yingchuang Renewable Resources, the first domestic manufacturer of recycled food-grade PET chips, has realized the closed-loop feedback recycling from PET bottle products made of virgin PET materials to recycled PET bottle-grade chips made from waste bottles and used for PET bottle products. , Reuse mode, and meet the review standards of the Ministry of Health and the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China. Its recycled PET chips are food-grade standards and can be used to produce food packaging.

According to Zhao Yan, the person in charge of Yingchuang, Yingchuang’s production line of PET raw materials-PET bottle products-post-consumer waste bottles-recycled bottle grade PET raw materials-PET bottle products can recycle and process 50,000 tons of waste PET bottles every year, reaching the entire Beijing 40% of the total amount of waste PET bottles, and 25,000 tons of materials that can be used to recycle PET bottles are manufactured.

Within the scope of Beijing, the total amount of PET plastic bottles discarded every year is as high as 150,000 tons, which is about 6 billion waste plastic bottles, which causes great harm to the environment. With the development of technology for manufacturing recycled PET chips, recycled food grade PET chips can be directly used for food packaging, thereby achieving 100% infinite recycling. The recycling of PET recycled plastic bottles greatly saves the consumption of petroleum resources.

At present, my country’s PET bottle production enterprises include not only large-scale backbone enterprises with advanced PET bottle automatic production lines manufactured by well-known companies in the world, but also a large number of simple and practical models with various degrees of automation designed and manufactured by my country. Small and medium-sized enterprises of the two-way PET blow molding machine present an unprecedented situation of flourishing and thriving.

With the development of the domestic economy and the improvement of industry policies, the market potential of recycled PET products will gradually appear, and more and more companies will enter the industry. If companies want to maintain their own competitive advantages, they must increase their scientific research. Investment to promote the upgrading of product structure. At the same time, pay attention to environmental protection in the production process, avoid secondary pollution, and truly realize the unity of social and economic benefits.

PET plastic bottles are not only widely used for packaging carbonated beverages, drinking water, fruit juices and tea beverages, etc., they are also the most widely used beverage packaging, and they are also widely used in food, chemical, pharmaceutical packaging and many other fields. PET plastic has a wide range of applications in the packaging field. Whether it is packaging film, roll material, or beer bottle, PET plastic is used. According to statistics, in recent years, the global PET production capacity has expanded at an average annual rate of about 9%, and my country’s PET production capacity exceeded 20 million tons in 2008, becoming the world's largest PET production and consumption country. Due to the continuous increase in social demand, the global PET polyester production is growing rapidly, and most of the PET products are disposable consumer goods, and a large amount of PET waste is generated. Waste PET materials are highly chemically inert, and are not easily degraded by air or microorganisms in a short time, which puts huge pressure on the ecological environment of the society.

Therefore, the recycling of PET plastic bottles can not only solve the environmental protection problem, but also can be used as a new raw material resource to alleviate the contradiction of the shortage of PET raw materials in China. Yes, looking back on China's 30 years of reform and opening up, although China has made world-renowned achievements in the economic field, it has also brought serious damage to China's environment. Water pollution, air pollution, etc. This has brought shrinkage to China's economy. People have gradually realized this problem, and accordingly put forward a series of measures to take the road of sustainable development, green GDP strategy, circular economy strategy, and so on. It can be seen that the recycling of PET plastic bottles is in line with the practical problems facing China, and is of great benefit to environmental protection, resource conservation, and sustainable development.

Recycled fiber is the main purpose of PET recycling. According to statistics, in 2007, the use of fiber in the application of recycled PET in my country reached 89%, which is widely used in clothing, furniture supplies, shopping bags, office supplies, daily necessities, civil engineering materials and other fields. For example, Guangdong Qiusheng Resources Co., Ltd. is one of the typical environmental protection enterprises that mainly produce recycled fibers. The company is committed to the research and development, production and sales of recycled polyester staple fibers. The main products include recycled cotton, medium-length, wool, and There are nearly one hundred varieties of product specifications such as hollow polyester staple fiber. As a resource recycling enterprise, Qiusheng Resources also pays great attention to environmental protection in the production process. It voluntarily promotes clean production, and has passed the clean production inspection and was rated as a clean production enterprise in Guangdong Province. It is understandable that the company seeks economic benefits, and it is commendable for the company. On the premise of maintaining the ecological environment, recycling social wastes, using technology to transform wastes, creating new value, and paying attention to environmental protection in the production process, and actively assuming the social responsibility of protecting the environment.
