Aluminum foil production and the development of the aluminum foil bags

China aluminum foil production began in 1932, but it was not until after the reform and opening up began to rapid development. Since the 1990 s, aluminum foil production entered an important period, not only to introduce a large number of advanced equipment, production management and technical development level also gradually towards the modernization and internationalization. Since this century, under the strong impetus of market demand, the aluminum foil production capacity increase quickly. Now there are more than 90 aluminum foil production enterprises in China, equipped with 66 sets of modern aluminum foil rolling mill, and there are 39 sets of universal cold rolling mill, aluminum foil a total capacity of up to 500000 tons/year. 【 Aluminum foil bags 】 The aluminum foil packing began in the early 20th century, when the aluminum foil as the most expensive packaging material, used only for high-grade packaging. Packed in aluminum foil chocolate Swiss candy company started in 1911, gradually replace the tin foil and popular. In 1913 the United States on the basis of the aluminium success also began to produce aluminum foil, mainly used in high-grade goods, life-saving supplies and packaging. In 1921 the successful development of composite aluminum foil board, mainly used as decorative materials and advanced packaging folding carton. Can be heat sealing type 1938 aluminum foil. During the second world war, the aluminum foil as the military packaging material to get fast development. Beginning in 1948 using aluminum foil containers packaging food. In the 1950 s, aluminum paper, lu: su composite started to develop. In the 70 s, with the mature of color printing technology, aluminum foil and aluminum-plastic composite packaging into a period of rapid popularization. Entering the 21st century, competition in the market and the trend of product homogeneity, stimulate the rapid development of the product packaging. The size of the global packaging market in 2002 has exceeded 500 billion dollars. The development of the aluminum foil packing basic synchronization with the industry development, in the Chinese market, aluminum foil packaging development faster, there are two main reasons: first, China's flexible packaging market development obvious gap with developed countries, consumer goods and food flexible packaging for a small proportion, developed countries have accounted for more than 65%, some of which have been more than 70%, while China accounts for about 15%, nearly two years the proportion of the rapid increase; Second, domestic lu: su composite paper, aluminum composite technology matures, reduce production cost, promote the aluminum matrix composites in China's packaging market to popularize and apply.
