What is the metal foil in the cigarette case?

The cigarette case is lined with aluminum foil paper.

Aluminum foil paper is widely used, such as aviation food packaging, ordinary meat packaging, cigarette packaging and so on. Experts divide it into more than 20 varieties according to their different application characteristics. Due to the differences of economic development levels in different countries, there is also a big gap 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 China 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 late, the market is growing rapidly and the prospect is eye-catching.

The application of aluminum foil paper in architecture is very significant. Sticking to the surface of thermal insulation material makes the construction more convenient and clean, especially the aesthetics has reached a new height. However, the effects of different kinds of aluminum foil paper are very different. For example, fireproof paper and ordinary paper are not of the same grade.
