Compared with metal, stone and wood, plastic products have the advantages of low cost and strong plasticity. They are widely used in the national economy. Plastic industry occupies an extremely important position in the world today. For many years, the production of plastic products has developed rapidly all over the world. Statistics show that the output of plastic products in China has always been in the forefront of the world rankings, and many kinds of plastic products have been in the first place. China has become a major producer of plastic products in the world.

From the point of view of demand, the per capita consumption of plastics in China still lags far behind that in developed regions of the world. According to statistics, as an index to measure the development level of plastics industry in a region, the ratio of plastics to steel in China is only 30:70, which is less than the world average of 50:50, and far less than that in developed regions such as the United States of America's 70:30 and Germany's 63:37. In the future, with the technological progress and consumption upgrading of modified plastics in China, the growth rate of plastic products in China is expected to be more than 10%. Plastic products are widely used, and the huge downstream industry provides strong support for the development of China's plastic products industry. With the promulgation of "Planning Rules for Revitalizing Petrochemical Industry", China's plastic products industry has ushered in new opportunities for development.

Investigation report shows that the high growth trend of plastic machinery and plastic mould industry, as well as the steady development of light industry such as household appliances, food, beverage, leather and toys, is also a favorable endogenous environment for the development of plastic industry; the steady development of automobile, medical plastics, real estate, especially supportive housing, has increased the demand of plastic products manufacturers. It has become a favorable external environment for the plastic industry. At the same time, the acceleration of exchange rate change, the increase of deposit reserve rate and interest rate, the rise of raw materials and labor costs, and the tense situation of electricity supply and demand also plague the plastic products industry and form a public shortfall.

On the basis of breakthroughs in the frontier technology of the plastic industry, we should focus on the key common core technologies and try to narrow the gap between the advanced and new production technologies in developed areas. The acceleration of technological progress will give more new functions to plastic materials and plastic products to meet the needs of the national economy.

Digital intelligent technology is a common enabling technology for product innovation and manufacturing technology innovation. It is the core technology of the new industrial revolution to deeply reform the production mode and industrial form of manufacturing industry. Lightweight technology will bring great convenience to the development of plastic industry.

In the future, lightweight materials will be more and more widely used in automobiles, airplanes and rail transit. Precision is an embodiment of advanced forming technology in plastic products processing industry, which is of great significance to the industry. Cleaner production and ecology will open up a new stage for energy saving and emission reduction in plastic processing industry.
