Ultra-thin pure iron foil packaging materials

An ultra-thin pure iron foil packaging material suitable for packaging electronic equipment and semiconductor devices has recently been successfully developed by a Japanese company, and the product is welcomed by related manufacturers.
According to reports, this ultra-thin pure iron foil is a pure iron film with an iron content of 99.99% or more. It has five advantages: First, it has high mechanical strength, which is equivalent to 3 times the strength of hard aluminum foil and 6 times that of soft aluminum foil. Second, it has high magnetic permeability, good magnetic absorption capacity and electromagnetic wave shielding ability; third, it has good moisture resistance; fourth, it is easy to apply adhesive and paint on the surface of pure iron film; Fifth, the thickness of iron foil. Only 20 microns and a width of 1.2 meters can be mass produced.
