The hottest package printing and environmental pro

Packaging and printing and environmental protection in recent years, due to the rapid rise and development of food, beverage, cigarette, medicine, health products, cosmetics, hardware, home appliances, clothing, toys and other industries, especially with the expansion of foreign trade, the market demand for packaging and printing products is increasing day by day; According to statistics, the annual demand of the American Printing Market in 2003 was as high as 162.4 billion US dollars, while the total output value of nearly 21000 packaging and printing enterprises in China in 2002 was only 75billion yuan

according to a preliminary survey, nearly 670 cities across the country have various types of printing machines, and the inks used are mainly divided into organic solvent inks, water-soluble inks, high solid inks and benzene free inks. Organic solvent based inks use toluene, xylene, acetone, butanol, ethyl acetate and other low boiling point volatile organic compounds as solvents, which have high printing speed, good print quality and low cost, so they are widely used. In the process of use, due to the volatilization of organic solvents, a large number of toxic and harmful organic waste gases will be produced, which will cause serious local pollution. If human beings are exposed for a long time, it will bring serious harm to the nervous system and hematopoietic function

most of the existing domestic or imported printing machines are not equipped with the corresponding purification device when leaving the factory. If the corresponding purification device is not set up separately, a large number of toxic and harmful waste gases (such as "triphenyl", acetone, etc.) will be directly discharged into the atmosphere during the production process, seriously polluting the urban atmospheric environment, which will cause non negligible harm to the urban environment and human survival. For example, in July 2003, when the six ministries, commissions and bureaus of the state carried out the national clean-up and rectification of the environmental protection market, a color printing company in Huli Industrial Zone, Xiamen City, Fujian Province has been ordered by the local environmental protection department to stop production for rectification because it produced without any environmental purification facilities, and the organic waste gas emitted made the surrounding people dizzy and vomit

according to the "China's environmental situation bulletin" released by the State Environmental Protection Administration, the population of cities with air quality standards in China only accounts for 26.3% of the urban population. Among them, the air pollution in super large and super large cities is significantly heavier than that in small and medium-sized cities. If it is not controlled in time, the urban air environment will further deteriorate. Therefore, the state and local governments have successively formulated some comprehensive , For example, the "comprehensive emission standard for air pollution coated PET bottles that can be completely recycled like pure PET bottle 1" (GB), which clearly stipulates the emission limits of various organic waste gases; At the same time, it is required that the environmental protection facilities of new or expanded projects, such as 000, must be checked and approved in strict accordance with the "three Simultaneities" (that is, at the same time, it coincides with the excellent opportunity for Chinalco to open the internal market, design, construct and put into operation at the same time), and the national unified certification system will also be established and fully launched. In the future, when enterprises apply for the certification of environmental management system ISO14000), quality management system (OHSMS) and other quality management systems, EPDA needs to get some characteristics that can represent its content from the page source file - keyword standard emission will become one of the important conditions
