Aluminum foil is a thin film made of aluminum material. It is light, flexible, moisture-proof, and anti-oxidant. Therefore, it has a wide range of uses in daily life and industrial production. The following are common uses of aluminum foil:
1. Food packaging: Aluminum foil can be used to package various foods, such as chocolate, cheese, candy, meat, bread, etc. It can effectively maintain the freshness and taste of food, prevent food from being affected by oxidation, moisture, odor, etc., and also prevent food from being polluted by the external environment.

4. Medical devices: Aluminum foil can be used to make packaging bags for medical devices, such as tourniquets, tablet packaging, etc. Its moisture-proof properties can effectively protect the safety and hygiene of the equipment.
5. Industrial production: In the field of industrial production, aluminum foil is usually used for electrolytic diaphragms, protective films on metal surfaces, capacitor foils, coated aluminum foils, etc. It plays an important role in electronics, construction, automobiles, aerospace and other fields.
6. Decorative packaging: The metallic luster of aluminum foil makes it an ideal decorative packaging material, which can be used for gift box decoration, bouquet packaging, candy gift box packaging, etc.
