Analysis of the development trend of China's plastic product
In recent years, China's plastic consumption has been rapidly added, but as China's plastic products are relatively backward in production technology, the production capacity in the high-end plastic products is relatively small, making the use of plastics in China Limited. In China, the use of plastics in cars is only half that in Europe, and some advanced engineering plastics are used less. It can be seen that there is a big gap between the use of Chinese plastics and the developed countries, which makes the comparison of the per capita consumption of plastics in China at that time with the developed countries in the world still has a big gap.
According to the market research center of EBO, the development direction of plastics can be summarized in two aspects. The first is to improve the performance, that is to modify the existing varieties by various methods to improve the comprehensive performance; two is the development function, that is, the development of polymer materials with physical functions such as light, electricity, magnetic and so on, so that the plastic can have photoelectric effect, thermoelectric effect, piezoelectric effect and so on.
Judging from the current speed of development of the world plastics industry, Germany and Sweden ranked first, followed by some countries in Japan and Europe, and the United States was slower. Foreign plastic packaging presents the following trends:
Copolymerized composite packaging film
At present, some countries in Europe and America invest in the development of non polar and polar ethylene copolymers, which will greatly improve the tensile and coextrusion properties of plastic film, improve the transparency, seal strength, stress resistance, crack resistance, and enhance stability, improve molecular weight cloth and extrusion rheological properties.
Foreign experts believe that the development of plastic industry in the world is focused on plastic modification, coating technology of plastic products, rapid biodegradation of waste plastic, and comprehensive recycling of plastics. For example, some European and American manufacturers adopt /PA bags filled with linear ethylene alpha copolymer and ethylene vinyl acetate copolymer, which are suitable for packaging ice cream, cream and other foods.
Multifunction composite film
A large number of multi-functional composite films have been developed abroad to further refine their functions. For example, the cold resistant film can withstand the low temperature environment of -18 C, -20 C and -35 C, and the moisture proof film made from the anti moisture treatment of PP can be divided into several kinds, such as moistureproof, dew proof, steaming cold, adjustable moisture, etc. the anticorrosion film can be packaged in perishable, acidity, and sweet food; the friction film stacking is stable; special PE thin. The film is chemical resistant and corrosion resistant, and the antimoth film is added with no odor proof agent; the heat resistant film of biaxial tensile nylon 66 is replaced by biaxially stretched nylon 6 packaged food, which is resistant to high temperature up to 140. The new special food packaging film can improve the fragrance protection of food packaging; the transparency of non crystalline nylon thin film is similar to glass and high shielding film. The stability of the color, aroma, flavor, nutritional index and taste quality; the metal protective film is packed with LDPE modified film for packaging liquid products and hot sealing in low temperature environment. PP paper improves the light resistance, cold resistance, heat resistance, water resistance, moisture resistance, oil resistance, acid resistance, alkali resistance and impact resistance of the package. Performance and so on.
At present, plastic cups and compound cups (outer PSP, inner PP, and PS) are widely used to pack cold, hot drinks, wine and convenience food. France uses PE bottles to pack fructose and yogurt. Germany uses PC bottles to pack milk. Our country uses PE bottles to pack medicine and so on.
When plastic products make life more convenient for people all over the world, it means that we can't leave plastic products, but the toxicity of plastic products has been controversial in recent years, and if we want to find materials instead of plastic products, it is believed that in the coming years it is a difficult task to complete, so try to perfect the plastic. The shortage of materials and the proper use of plastic products are the kingly way.
At present, the development trend of domestic plastics industry is divided into three steps: agricultural plastics (including agricultural plastic film, water-saving and geosynthetics) occupy the most important position in various subdivision products; packaging materials and plastic materials have become the field of rapid growth; the production of conventional products, such as pipe material, thin film and so on, will be gradually developed. At the same time, the high-tech, high value-added engineering plastic products and composite materials are expanding with the consumption of the downstream industry. At present, China is in the period of the transition from the second stage to the third stage.
Many factors such as the fierce competition of traditional products are forcing China's plastic industry to enter the high-end field. Some enterprises with their own characteristics in the industry will continue to maintain a good momentum of development. The biggest driving force for growth should be to develop more sustainable products, and enterprises with technical advantages will be in the future. The market has an obvious advantage.
In foreign terms, according to a report issued by the India plastics foundation, the per capita consumption of the plastic industry in India is expected to double in the next five years with the increase in plastic, consumer packaging and government infrastructure investment. India's per capita consumption of plastic is estimated at --2012-13 kilograms in the year of 9.7 - far less than the 109 kg in the United States and 45 kg in China. But the plastics industry will benefit from India's per capita income growth, consumption expenditure increase and modernization level, especially in urban areas.
The India plastics Foundation estimates that the demand for polymer in India will increase from 11 million tons in 2012-13 to 16 million 500 thousand tons in 2016-17 years, promoting a compound annual growth of 10.8% of plastic consumption. According to the report, India is expected to rank among the world's ten largest packaging consumers by 2016, and the total demand is expected to reach US $24 billion.
At present, urbanization and globalization have become the trend of social development.
