Widest Aluminum Foil

At present, the production technology of aluminum foil is relatively mature. The width of aluminum foil can reach more than 2000 mm (2 meters), and the maximum width of aluminum foil can reach 2100 mm. Some high-end aluminum foil products, such as aluminum foil used for food packaging or electronic products, usually have more stringent thickness and width requirements.

Only professional aluminum foil manufacturers can produce ultra-wide aluminum foil, because the increase in width will bring some technical difficulties in the production process of aluminum foil, including:

- Uniformity control: Widest aluminum foil needs to maintain uniformity of thickness and width during rolling to ensure product quality.

- Equipment requirements: The production of wide-width aluminum foil requires high-precision rolling mills and related equipment, which have high investment and maintenance costs.

Ultra wide aluminum foil is mainly used in the following fields:

1. Packaging field

- Aseptic packaging:

It is widely used in aseptic packaging of milk, beverages, etc., such as common aseptic packaging boxes for milk and juice, which can be compounded with multi-layer materials such as paper and polyethylene to effectively isolate oxygen, moisture and light, ensure the freshness and quality of the product, and extend the shelf life.

- Food packaging:

It can be used to package meat, vegetables, fruits and other foods to keep them fresh, prevent moisture and odor. It can also wrap food when baking so that the food is heated evenly and prevent the bottom from burning.

- Medical packaging:

As a packaging material for tablets, capsules and other medicines, it can protect the medicines from moisture, oxygen, light and other factors, ensuring the quality and stability of the medicines during storage and transportation.

2. Electrical and electronic fields

- Battery manufacturing:

It is a key material for power battery cells, mainly used for positive current collectors and aluminum-plastic films. With the rapid development of the new energy vehicle industry, the demand for ultra-wide battery aluminum foil is growing.

- Electromagnetic shielding:

Because of its good electromagnetic shielding performance, it can be used for materials such as inner tapes and shielding layers of electronic equipment to prevent electronic equipment from being interfered by external electromagnetic interference, and also to avoid the electromagnetic radiation generated by the equipment itself from affecting the surrounding environment.

3. Building field:

It can be used as the insulation layer of building insulation materials, which can effectively block the external temperature and water vapor, improve the thermal insulation performance of buildings, and reduce energy consumption. Used in the roofs, walls and other parts of some buildings, it helps to maintain a stable indoor temperature and save energy costs for air conditioning and heating.

4. Home appliance field:

For example, hydrophilic aluminum foil for air conditioners can improve the efficiency and corrosion resistance of air conditioner heat exchangers. In addition, it is also used in home appliances such as refrigerators and freezers for heat insulation and moisture resistance, etc., to improve the performance and service life of home appliances.
