Aluminum foil is aluminum thin sheet with a thickness less than 0.2 mm, thinner gauges down to 0.006mm. It is widely used in food packaging and industrial production because of its excellent characteristics. It has excellent barrier properties, thermal and electrical conductivity and reflectivity, etc. These physical properties bring more protection to the product, reduce the energy required for cooling, and extend the shelf life of the product.

Production Process
The aluminum foil manufacturing process generally goes through casting, homogenization, surface treatment, hot rolling, cold rolling, foil rolling, washing, winding, annealing, and finally cutting.
Aluminum foil structure
Aluminum is a very active metal, so it is easily oxidized by oxygen in the air to form aluminum oxide at normal temperature and pressure. Aluminum oxide is a dense protective film, which can prevent some substances from further corroding aluminum.
Classification of Aluminum Foil
- Classification by thickness
Thick foil: With a thickness of 0.1-0.2mm.
Single zero foil: With thickness ≤0.1mm.
Double zero foil: With two zeros after the decimal point when its thickness is measured in mm, usually the thickness is less than 0.0075mm.
- Classification by temper
Hard foil: Without softening treatment (annealing) after rolling.
Semi-rigid foil: Hardness is between hard foil and soft foil.
Soft foil: After rolling, it has been completely annealed and softened. The material is soft and has no oil residue on the surface.
- Classified by processing status
General foil: Without any other processing after rolling.
Embossed foil: With various patterns on the surface.
Composite foil: Formed by pasting aluminum foil, paper, plastic film, and cardboard together.
Coated foil: Coated with various resins or paints on the surface.
Colored foil: Coated with color on the surface.
Printed foil: With various patterns, patterns, characters or pictures printed on the surface.
