thin Aluminum foil – thin aluminum sheet is produced by cold-way and having a thickness of from 0.005 to 0.2 mm. Aluminum foil has excellent density, good water resistance and anti-air permeability, may also be exposed to high temperatures without deforming or melting, etc. therefore can be used in various fields of business, packaging, automotive and construction, etc.

thin aluminium foil has unique deadfold characteristics which make it ideal for wrapping and re-wrapping many different products and product shapes, while minimising the need for sealants. Because it is very malleable it can be easily deformed without losing its barrier integrity, making it an ideal material for use in combination with other flexible substrates to create very thin laminates for a variety of markets and consequently, again, save resources.
thin Aluminum foil has many characteristics, so it is vastly used as packaging aluminum foil, such as food, drink, cigarette, pharmaceutical, aluminum household foil, etc. Besides, it can also be used as electronic capacitor material, building material, heat insulation material, printing material, sign or label material and so on and so forth. Among all these applications, using as packaging material can greatly express the features of aluminum foil. haomei Aluminum foil can manufacture varieties of aluminum foil with high quality, and has won good praise from our customers
Thin aluminum foil gauges down to 6μm (0.24 mil) are also commonly used.Standard household foil is typically 0.016 mm (0.63 mil) thick and heavy duty household foil is typically 0.024 mm (0.94 mil).
It has unique mechanical properties as it is formable, strong and can be ‘dead folded’, which is beneficial when aluminum foil wrapping food;

3. High cupping value
What is the production of industrial aluminium foil roll ?
Aluminium foil can be produced through he « DC Process » or the « CC Process », both process able, with current technology and equipments, to produce good quality of thin aluminium foil. For the DC Process, the aluminium foil is produced by first rolling heated aluminium ingots (hot rolling) down to coils with gauuge of 2 to 4 mm, and then cold rolled by several passes to the required foil gauge. For the CC Process the molten metal is converted directly (continuous casting) into a coil with a gauge of 5-6 mm, which will be cold rolled to the finish requested gauge.
When the foil has reached the final gauge, the coils are slitted to final widths and coils size, before to be annealed in special furnace. For many applications, the annealing of the foil is a critical step, in order to remove all organic wastes and be absolutely clean for food contact, and to get the final mechanical properties for optimized running.
Aluminum foil supplanted tin foil in the mid 20th century.Because of Thin foils are fragile and are sometimes laminated to other materials such as plastics or paper to make them more useful.
