The double-zero aluminum foil tackiness phenomenon includes two layers of meaning: the mechanical properties of the aluminum foil are not suitable for use and the degreasing effect of the aluminum foil surface is poor

Aluminum foil is a high-grade packaging material, which can replace large-area anodized aluminum bronzing and hot silver.

Aluminum foil has the advantages of light weight, airtightness and good covering property. It has been widely used in many sectors of the national economy and people's daily life, but it is mainly used in packaging, electromechanical and architectural fields.

The sheet and foil produced by the aluminum industry is widely used in the food industry and the pharmaceutical industry because aluminum is non-toxic, non-adsorbing, non-fragile, inhibits bacterial growth and can be cleaned with steam.

Since the 1980s, the packaging industry has been an important consumer market for aluminum. In the 21st century, the application of aluminum in the packaging industry has developed faster.

The so-called double-zero aluminum foil is a foil having two zeros after the decimal point in the thickness of mm, and is usually an aluminum foil having a thickness of less than 0.0075 mm.
