Aluminum foil is a thin sheet made of aluminum metal, usually less than 0.2 mm thick. It has good ductility and plasticity, and can be pressed into thin sheets through a rolling process. Aluminum foil has a wide range of applications, especially in food packaging, medical, industrial and other fields.

Features of aluminum foil
Lightweight and durable: aluminum foil is lightweight but has high strength and durability.
Good moisture and corrosion resistance: it can effectively prevent the entry of moisture, air, odor and light, so it is widely used in food packaging and pharmaceutical packaging.
Good thermal and electrical conductivity: the thermal and electrical conductivity of aluminum foil are very good, suitable for some industrial fields.
Recyclability: aluminum foil is a recyclable material and meets environmental protection requirements.
Good ductility: aluminum foil can be easily bent, folded and cut to meet different shape and size requirements.
