Aluminum foil is a versatile, thin sheet of aluminum metal, typically less than 0.2 mm thick. It is produced by rolling aluminum ingots to the desired thinness and can have a glossy or matte finish. Known for its flexibility and ability to be easily molded, it acts as an excellent barrier against light, oxygen, moisture, and bacteria. Aluminum foil is non-toxic, odorless, and tasteless, making it ideal for food packaging, cooking, and storage. It is available in different types, including household, heavy-duty, and industrial, each suited for specific applications. It is also 100% recyclable without any loss in quality.
Aluminum foil's key features include its barrier properties, protecting against light, gases, and moisture, which helps preserve aroma and product characteristics. It also offers thermal resistance, reflecting up to 98% of radiant heat, making it suitable for insulation and baking. The material is durable, corrosion-resistant, and can withstand temperatures from deep-freeze to oven. Aluminum foil is manufactured in varying thicknesses, ranging from ultra-thin (less than 9 μm) to heavy-duty (26-40 μm), to meet diverse needs. Common alloys used in its production include the 1xxx, 3xxx, and 8xxx series, with small amounts of other elements added to enhance specific properties.
The price of aluminum foil varies based on factors like aluminum market prices, thickness, specifications, production processes, and order quantity. As of early 2025, Chinese aluminum foil prices ranged from $3,200 to $3,800 per ton FOB for standard household-grade rolls (7–30 microns). Prices are subject to fluctuations due to seasonal cycles and geopolitical factors. Aluminum foil is widely available in rolls and sheets at grocery stores, supermarkets, and online retailers like Walmart and Uline. For instance, Uline offers standard aluminum foil rolls (12" x 1,000') starting at $69.
