Metallic Foil

Metallic foil is supplied by manufacturers who specialize in numerous and specific industries, applications and customer needs. Metallic foil is very application specific which covers a wide variety of alloys, tempers and gauges and so there are many different products.

Because of the physical characteristics of the metallic foil such as the grades, purity, composition the manufacturing of foil needs specialized and experienced attention. Die cutting very thin malleable foil such as 0.003-0.010” has to be treated and handled very carefully in the manufacturing process as the foil is easily damaged and the quality of the final product will not be acceptable. 

Metallic foil is usually supplied in roll form and in various roll widths. It is usually sold in hundreds of feet lengths on a cardboard core. The most common metallic foil that we die cut is aluminum.
