Our aluminum foil rolls are available in pack rolled, two sides bright, and mill finish. They provide reliable yet flexible protection for any variety of products or industrial needs. Finally, our aluminum foil tape is available in gauges from .0005” to .020”.
Aluminum foil is produced by rolling aluminum slabs cast from molten aluminum in a rolling mill to the desired thickness. To maintain a constant thickness, a technician monitors the rolling mill sensors to ensure the pressure on the slab is correct. Sensors are able to tell the technician if the pressure is too great or not enough and then the technician can adjust the rollers to apply more or less pressure. It is then coiled and sent to the cold rolling mill. To avoid breakage because of the thinness, the foil is doubled in the cold rolling mill and the rolled to the desired thickness. Aluminum foil provides a complete barrier to light, oxygen, moisture and bacteria. For this reason, foil is used extensively in food and pharmaceutical packaging. It is also used to make aseptic packaging that enables storage of perishable goods without refrigeration.
Our aluminum foil products are easily machined or cast, depending on your needs. Along with our aluminum foil products, we have the capability to supply material on aluminum, steel, fiber, and plastic cores with 1 5/16” to 20” diameters. With extreme pliability and stability against normal atmospheric corrosion, aluminum is truly a superior material.
In selecting the proper aluminum foil product for a given application, consideration must be given to a variety of properties. Before purchasing aluminum foil, aluminum rolls, coils or more, know the strains it will be under during use. Properties to pay attention to include:
Tensile strength
Formability
Wettability
Weldability
Corrosion resistance
