6.5 micron aluminium foil

6.5 micron aluminium foil In 2020, the annual demand for aluminum foil in China's packaging industry will reach 350,000 tons, and it is expected that the consumption will exceed 900,000 tons in 2021. Among them, the demand for food packaging 6.5 micron aluminium foil is the most obvious. 　 　
　 Aluminum foil is most commonly used in the field of food packaging. It is a soft metal film that has the advantages of moisture resistance, airtight shading, fragrance retention, non-toxic and tasteless, and long-term preservation of food.

The production history of aluminum foil can be traced back to the beginning of the 20th century. Before 1900, people could only produce small batches of aluminum foil through arduous and laborious hammering processes. In the past 100 years, scientists have continuously improved production technology and equipment to make aluminum foil thinner and thinner. The output has also been greatly increased, broadening the application fields of aluminum foil, from the early chocolate and butter wrapping paper to the current development of beverage packaging, bottle caps, cigarette boxes, aluminum foil hydrogen balloons, etc. The thinnest can be 5.3 6.5 micron aluminium foil. 　　
　　
6.5 micron aluminium foil is very versatile, such as: aviation food packaging, ordinary meat packaging, cigarette packaging, etc. Relevant experts divided it into more than 20 varieties according to its application characteristics. Due to differences in the level of economic development in different countries, there are also large gaps in the consumption structure of aluminum foil. In developed countries in Europe and America, aluminum foil products for packaging account for 70% of the total demand. In the Chinese market, aluminum foil is mainly used as raw and auxiliary materials for industrial manufacturing, and packaging aluminum foil only accounts for 30% of the total domestic demand. Although the development of aluminum foil packaging is relatively late, the market is growing rapidly and the prospects are attracting attention.
