reduzir muito o pinhole is a kind of good performance of pharmaceutical packaging material, used as drug bubble packaging. Aluminum foil packaging can be traced back to the early 20th century, at that time the production level of science and technology is not very developed, aluminum foil has been regarded as one of the most expensive packaging materials, that is the status of aluminum foil is only used for high-grade products packaging. Dentro 1911, a Swiss confectionery company began to try to wrap chocolate in aluminum foil, which had been used in the form of foil packaging until then, and gradually became popular instead of tin foil. Two years later, in 1913, the United States on the basis of the success of the aluminum smelting process, began to produce aluminum foil, the main role is used in some high-grade goods, life-saving supplies, and chewing gum packaging.

With the refining of production, para 1921 the United States successfully developed a composite aluminum foil cardboard, which is mainly used for decorative board and advanced folding carton packaging. Dentro 1938, the heat-sealing aluminum foil paper was produced, and the use of aluminum foil was more widespread. During the Second World War, aluminum foil was widely used as military packaging materials, and the development of aluminum foil was further improved. Then in 1948, aluminum foil began to be processed into aluminum foil containers for food packaging. In the 1970s, the printing process was gradually improved. With the maturity of color printing technology, the use of aluminum foil and aluminum-plastic composite packaging materials entered a period of rapid popularity.

Due to the good characteristics of aluminum foil as packaging, China also began to use aluminum foil as packaging material, but the progress of development is not as fast as some foreign countries. De 1932, aluminum foil was initially used in China. But it was not until the reform and opening up more than three decades later that the aluminum foil packaging product began to develop rapidly. With the end of the war and the improvement of people’s living standards, people’s pursuit of material also improved. After the 1990s, the production of aluminum foil as packaging supplies entered an important period. China has not only introduced a large number of advanced production equipment, but also greatly improved the level of production management and technological development, and gradually moved toward modernization and internationalization. Under the promotion of this background, since this century, the market demand has increased a lot, aluminum foil capacity has been rapidly improved.

After entering the 21st century, various production processes and technical means have made great progress, and there is more room for development in the aluminum foil industry, but at the same time, it has also brought about fierce market competition and the trend of product homogeneity. This also directly stimulated the rapid development of product packaging. The development of the aluminum foil packaging industry is basically in step with the development of the packaging industry. Compared with foreign countries, the development of aluminum foil packaging in the Chinese market is faster and faster.

Contribute to this situation for two reasons: one is in the flexible packaging market in China compared with some developed countries gap on technology, consumer goods, food of flexible packaging in China, embalagem de folha de alumínio medicinal for a small proportion, accounted for about 15%, and the basic in some developed countries accounted for more than 65%, even some countries have already exceeded 70%. reduzir muito o pinhole, the proportion began to increase rapidly: Segundo, China has made a lot of breakthrough progress in aluminum-plastic composite and aluminum paper composite technology, production technology, and production equipment are constantly mature, and the production cost is also much lower than before. This also directly promotes the popularity and application of aluminum foil composite materials in China’s packaging market.
