We know that pure aluminum is easy to oxidize, so 8021-0 aluminum foil will form a dense oxide film on its surface, don't underestimate this oxide film, it can help 8021-0 aluminum foil completely defeat the iron sheet non-rust properties. 8021-0 aluminum foil has high plasticity, and is widely used in heat preservation rooms, and is safe.
In addition, the appearance of the aluminum skin is neat, smooth, and looks very beautiful. It not only gives people visual enjoyment, but also achieves anti-rust, waterproof and heat preservation effects in terms of performance. Although 8021-0 aluminum foil is not familiar, any experienced expert will definitely make good use of 8021-0 aluminum foil to achieve the goal of high quality and low price. The value of 8021-0 aluminum foil is very high, and it can meet the requirements of many special occasions. It is widely used in house construction and pipeline production materials. Finally, when we choose 8021-0 aluminum foil, we need to pay attention to the color of 8021-0 aluminum foil.
8021 aluminum foil has 7 characteristics:
(1) The surface is clean and hygienic, and no bacteria or microorganisms can grow on the surface.
(2) 8021-O state aluminum foil is a non-toxic packaging material, which can be in direct contact with food without any danger to human health.
(3) 8021-O state aluminum foil is a tasteless and odorless packaging material, which will not make the packaged food have any peculiar smell.
(4) No matter at high temperature or low temperature, the 8021-O state aluminum foil will not have the phenomenon of grease penetration.
(5) 8021-O state aluminum foil has high hardness and high tensile strength, but its tear strength is small, so it is easy to tear.
(6) 8021-O state aluminum foil is an opaque packaging material, so it is a good packaging material for products exposed to sunlight, such as margarine.
(7) 8021-O state aluminum foil has good plasticity, so it can be used to package products of various shapes. Containers of various shapes can also be made arbitrarily.
