A Guide to Aluminum Foil

Aluminum Foil- Aluminum is the third most abundant element on earth. It is extracted from bauxite. Bauxite is refined to make a pure aluminum oxide call alumina. The alumina is charged with an electrical current. This process is know as electrolic reduction. The metal produced from this process is added to a wide variety of alloys allowing them to provide specific characteristics suited for a variety of applications.

Aluminum foil manufacturers (HTMM GROUP) commonly use pure aluminum. In recent years it has become popular to add a variety of aluminum alloys engineered to add strength and reduce thickness of the aluminum foil.

Once the alloy mixture is determined it is melted and poured onto a cast and rolled to form a large sheet of aluminum foil. The rolling process is repeated until the desired thickness is reached. The main factors in reaching the desired thickness is roll pressure, mil speed, and rolling oils. As the aluminum foil is rolled into the desired thickness, it is spooled on large stock coils to hold the aluminum foil.

From the large coils the aluminum foil is unspooled, cut, and spooled onto smaller cardboard spools. Once the aluminum foil is spooled onto the smaller spools it is placed into boxes and prepared for shipping. The roll width, length, and thickness determines the amount of boxes per case, and cases per pallet.
