1. According to different materials
1. Pure aluminum foil: The material is pure aluminum, which is often used for packaging of foods such as baking, barbecue, and vegetables.
2. Alloy aluminum foil: The material is a mixture of multiple elements, and is mainly used for packaging in the industrial field, such as electronic components, aerospace equipment, etc.
2. According to different thicknesses
1. Light and thin aluminum foil: The thickness is generally between 0.005-0.009mm, mainly used for packaging of food, medicine, etc.
2. Medium and thick aluminum foil: The thickness is generally between 0.01-0.1mm, mainly used for liquid containers, box packaging, etc.
3. Thick and heavy aluminum foil: The thickness is generally between 0.1-0.2mm, mainly used for building insulation, aircraft insulation, etc.
3. According to different surface treatment methods
1. Smooth aluminum foil: The surface is smooth, suitable for processing such as printing, embossing, and lamination.
2. Textured aluminum foil: The surface has certain textures, which is suitable for direct coverage on food, increasing friction and making food less likely to fall off.
4. According to different application scenarios
1. Food-grade aluminum foil: aluminum foil for food packaging that meets national standards, safe and hygienic.
2. Medical-grade aluminum foil: used for packaging of medicines, requiring good sealing, moisture-proof and anti-oxidation.
3. Industrial-grade aluminum foil: used for packaging in various industrial fields, requiring stable materials and corrosion resistance.
In general, different types of aluminum foil have different characteristics and application scenarios due to different materials, thicknesses, surface treatment methods, etc. When purchasing aluminum foil, you should choose the appropriate model according to actual needs.
