Definition and manufacturing process
Single sided light aluminum foil: This type of aluminum foil is manufactured through a double rolling process, that is, during the rolling process, one side of the aluminum foil is in contact with the roller, while the other side is not. After rolling, one side is bright and the other side is black. Its thickness usually does not exceed 0.025mm.
Double sided light aluminum foil: This type of aluminum foil is made by rolling a single sheet, and both sides are in contact with the roller. Due to the different surface roughness of the roller, double sided light aluminum foil is divided into mirror double sided light aluminum foil and ordinary double sided light aluminum foil. Its thickness is generally not less than 0.01mm.

Advantages of single (double) sided smooth aluminum foil:
Performance advantages of single-sided smooth aluminum foil:
Heat reflectivity: The bright side has higher heat reflectivity and can effectively reflect heat.
Insulation: Since the bright side can reflect light and heat, it is often used in occasions that require insulation.
Lower price: The production process is relatively simple, and the price is lower than that of double-sided smooth aluminum foil.
Good moisture resistance and air tightness: Aluminum foil has good moisture resistance and sealing properties, which can prevent the penetration of water vapor and gas.
Features of double-sided smooth aluminum foil:
Stronger heat reflectivity: Since both sides can reflect heat, the reflectivity of double-sided smooth aluminum foil is better than that of single-sided smooth aluminum foil.
Uniform appearance: Since both sides are bright, it is suitable for applications with high requirements for appearance.
Long service life: Since both sides are corrosion-resistant, moisture-proof and heat-resistant, the service life is longer.
Application areas:
Single-sided smooth aluminum foil:
Insulation material: used for insulation layer in buildings or insulation wrapping of pipes.
Food packaging: In food packaging, the smooth surface is used to reflect light and extend the shelf life of food.
Home appliance industry: used as insulation or reflective material in appliances such as air conditioners and refrigerators.
Double-sided smooth aluminum foil:
High-end packaging material: used for high-end food and pharmaceutical packaging, which plays a protective and aesthetic role.
Building reflective material: used for efficient insulation and heat preservation in construction projects, especially in situations where double-sided reflection is required.
Electronics and home appliance industry: used for shielding and reflective materials for electronic equipment.
