Compared with metal, stone and wood, plastic has the advantages of low cost and strong plasticity. It is widely used in the national economy. The plastic industry occupies an extremely important position in the world today. The production of plastic products has developed rapidly all over the world for many years. The output of China's plastic products has always been in the forefront of the world rankings. Among them, the output of many kinds of plastic products has been ranked first in the world. China has become the world's largest producer of plastic products. From 2001 to 2010, the average annual growth rate of China's plastic products output remained above 15%. In 2010, China's total output of plastic products reached 58.3 million tons.
Although China's total consumption of plastic products has ranked second in the world, the per capita consumption of plastics is far behind that of developed countries. Data show that in 2005, China`s per capita plastic consumption was only 29.5 kg. In the same year, the per capita plastic consumption of the United States, Belgium, and Germany reached 171 kg, 169 kg, and 155 kg, respectively, which were 5.79 times, 5.73 times, and 5.79 times that of China`s per capita plastic consumption. 5.25 times.
As another indicator to measure the development level of a country's plastics industry, the ratio of plastic to steel is only 30:70 in China, which is less than the world average of 50:50, and far less than the 70:30 of the United States and 63:37 of developed countries such as the United States and Germany. From another aspect, these gaps show that China's plastic products and plastic machinery industries have greater room for development.
The Chinese plastics machinery market has attracted more and more attention from foreign companies. On the one hand, many large international companies continue to increase the depth and breadth of cooperation with Chinese plastics mac
