Some analysts predict that from now until 2015, China's plastic raw materials and resins will have rapid growth. Several world-class large-scale ethylene projects will be expanded, and the total amount of ethylene in the “Eleventh Five-year Plan†will reach approximately 8.5 million tons. The resin will increase substantially, providing the raw material basis for the development of the plastics industry. From the perspective of per capita consumption, the average per capita consumption in China is only about 12 kg, while in developed countries it is 30 kg to 100 kg, and the average world consumption is also 18 kg. Therefore, The development prospects of China's plastics industry are very broad. In the past 10 years, the world's plastics applications have continued to expand. In the next 10 years, the world's plastic products will grow at a rate of 3% per year. By 2010, the total output of plastic products in the world will reach 186 million tons.
The future development of plastics industry in China will be mainly in agricultural plastic products, agricultural plastic water-saving equipment, plastic packaging products, construction plastic products, industrial transportation and engineering plastic products and other aspects. The relevant plastic water-saving and energy-saving packaging products are described as follows:
Agricultural plastic products: According to the inaccurate statistics of the China Plastic Film Association's Agricultural Film Specialist Committee, the entire industry already has nearly 1,000 agricultural film production enterprises of different sizes, with a production capacity of over 2 million tons, and actual output exceeding 1 million tons/year. More than 60 companies have an annual production capacity of more than 10,000 tons. There are about 30 large-scale backbone enterprises, and their production capacity and annual output account for 60% of the national total. Together with me, I have become the country with the largest output and usage of agricultural film in the world. According to the statistics of the Ministry of Agriculture, in 2005, the cultivated area of ​​China's horticultural facilities reached about 867,000 hectares, and the country's mulching area reached 0.12 billion hm2. This was combined with forage film, plastic nursery containers for ammoniated membranes, silage membranes, and stretch film. Shade nets, insect-proof fields, fishing nets, agricultural product storage and preservation materials, pesticides, foam plastic plates, etc., require approximately 3 million tons of plastic products per year.
Agricultural plastic water-saving equipment: According to the preliminary planning of the water conservancy department, the area of ​​water-saving irrigation projects should reach a new water-saving irrigation area of ​​0.093 billion hm2 on the basis of the current 117 million hm2, with a cumulative total of 27 million hm2. Of which, 5.267 million hm2 were sprayed, 667,000 hm2 were drip-irrigated, and 930,000 hm2 of water was transported through the pipeline. The canal was impervious to 3.333 million hm2. All kinds of plastic water-saving devices such as pipes and fittings, emitters, nozzles, impermeable membranes, and geotechnical engineering were needed. Weaving fabrics and other 1.7 million tons / year.
Energy-efficiency benefits of plastic products: Plastic building materials not only can replace steel and wood instead of traditional building materials, but also have the advantages of saving energy and materials, protecting the environment, improving the living environment, improving the function and quality of the building, reducing the weight of the building, and the convenience of construction. The energy-saving benefits of plastics are very prominent, and their energy-saving benefits are reflected in the two aspects of saving production energy consumption and energy consumption. In terms of production energy consumption, plastic products account for 1/4 and 1/8 of the energy consumption of steel and aluminum production, and rigid PVC plastic production consumes only 30% to 50% of cast iron pipes and steel pipes, and plastic water supply pipes are better than metals. Pipes reduce production energy consumption by up to 50%.
Packaging plastic products: Packaging is still the largest area of ​​plastics applications, and its development still exceeds that of other traditional packaging materials. China's cement and chemical fertilizer production rank first in the world. Currently, more than 50% of cement packaging uses composite woven bags, as well as mineral products, synthetic resins for chemical products, raw salt, sugar, cotton, and wool. Due to the lack of paper and jute resources in China, plastic packaging as the main packaging material is an inevitable trend.
China is a large country for food production. Its annual production is close to 500 million tons and it requires a lot of packaging materials. The small package of grain in our country has already started and made progress in some big cities. For example, the ratio of small packages for food sales in China reaches the level of developed countries, and at least 1.1 million tons of plastic substrates are required per year. Food, beverages, pharmaceuticals, detergents, cosmetics, chemical products, etc. are rapidly developing in China. They have a great demand for packaging products such as composite films, packaging films, containers, turnover containers, and plastic trays. For example, the output of beverages is basically The doubling in five years is expected to reach about 30 million tons by 2010, of which 50% will use polyester bottles, which will require about 12 billion. There are several million tons of various packaging materials for convenience foods, dairy products, canned foods, monosodium glutamate, candies, and biscuits. There is also a large market for pharmaceutical packaging. In summary, the total demand for packaging materials is approximately 5.5 million tons per year.
