Aluminum foil is a thin sheet rolled from metal aluminum. It is a soft metal film with soft texture, good ductility and silvery white luster. It is widely used in packaging materials for food and medicine, materials for electrolytic capacitors, and thermal insulation materials for buildings, vehicles, ships, etc.

Features of aluminum foil
Aluminum foil has a clean, hygienic and shiny appearance. It can be made into integrated packaging materials with many other packaging materials, and the surface printing effect of aluminum foil is better than other materials. In addition, aluminum foil has the following characteristics:
(1) The surface of the aluminum foil is extremely clean and hygienic, and no bacteria or microorganisms can grow on its surface.
(2) Aluminum foil is a non-toxic packaging material, which can be in direct contact with food without any danger of harming human health.
(3) Aluminum foil is an odorless and odorless packaging material, which will not make the packaged food have any peculiar smell.
(4) If the aluminum foil itself is not volatile, it and the packaged food will never dry or shrink.
(5) No matter in high temperature or low temperature, the aluminum foil will not have the phenomenon of grease penetration.
(6) Aluminum foil is an opaque packaging material, so it is a good packaging material for products exposed to sunlight, such as margarine.
(7) Aluminum foil has good plasticity, so it can be used to package products of various shapes. Various shapes of containers can also be arbitrarily formed.
(8) Aluminum foil has high hardness and high tensile strength, but its tear strength is small, so it is easy to tear.
(9) The aluminum foil itself cannot be heat sealed, and a heatable material, such as Pe, must be applied to its surface to be heat sealed.
(10) When aluminum foil is in contact with other heavy metals or heavy metals, there may be adverse reactions.
