Aluminum foil jumbo roll is a large roll of thin, flexible aluminum metal that is used for packaging, insulation, cooking, and other purposes. It is typically sold in large rolls that can be used to create smaller, individual rolls of aluminum foil that are more suitable for household or commercial use. The jumbo rolls are popular in food packaging industries and are typically made of high-quality aluminum alloy materials that offer excellent protection against moisture, light, and oxygen. These jumbo rolls are also used in various industrial applications such as aerospace, automotive, and construction industries. They come in different sizes and thicknesses, depending on the intended use.
There are various alloys and temper grades of aluminium foil jumbo roll available in the market. Some of the common alloys used for manufacturing aluminium foil jumbo roll are:
1. 8011: This is the most commonly used alloy for making aluminium foil because of its high tensile strength, good ductility, and low weight.
2. 1235: This alloy is used for making household foil as it has high thermal conductivity and excellent workability.
3. 3003: This alloy has higher strength and thickness than 8011 alloy and is commonly used for making foil containers.
The temper grades of aluminium foil jumbo roll are:
1. O (annealed): This is a soft temper grade used for general-purpose applications where flexibility and ductility are required.
2. H22, H24, and H26: These are semi-hard temper grades used for applications that require higher strength and improved formability.
3. H18: This is a hard temper grade used for applications that require a higher level of strength and stiffness.
