The thickness of standard household aluminum foil is about 10 microns to 20 microns. 18 micron aluminum foil is a popular aluminium foil thickness. It is widely used in cooking, freezing, fresh-keeping, baking and other industries. This disposable aluminum foil paper is convenient to use, safe, hygienic, has no peculiar smell, and does not leak.
In the refrigerator or freezer, you can directly wrap the aluminum foil on the food, which can keep the food from deforming, and prevent the water loss of fish, vegetables, fruits, and dishes, and prevent the leakage or mixing of flavors. Because aluminum foil has good and uniform thermal conductivity and heating effect, it can be used in ovens, steamers, etc. to heat directly.
Battery aluminum foil is mainly used as a current collector for lithium-ion batteries and as a current collector. Commonly used lithium battery pure aluminum foils have alloy grades such as 1060, 1050, 1145, 1235, and the states are O, H14, H18, H24, H22, etc. The battery aluminum foil thickness is 10-50 microns. Aluminum foil for batteries has many excellent features, and its usage is increasing year by year.
At present, there are three main types of aluminum foil used for pharmaceutical packaging, namely 8079 aluminum foil, 8021 aluminum foil, and 8011 aluminum foil. The three mainly have a little difference in metal element content and thickness. 8011 aluminum foil, also known as PTP aluminum foil, has a thickness of 16-40 micron.
Its silicon content is high, and it contains manganese and iron, which has high strength and corrosion resistance. It is often used in the packaging of medicine capsules or the back of medicine boards in pharmaceutical packaging, and it is also used for bottled liquids (such as antibiotics, infusion and other medicine bottle caps).
The rolling process of 18 micron aluminum foil is with complex process, advanced equipment and high technical content. During the production process, there are strict requirements on alloy composition control, impurity removal and filtration, precision cutting, and rolling speed.
The aluminum foil blank is a cold-rolled aluminum coil with a thickness of 0.4-0.7mm and a high multiple deformation rate. The aluminum foil blank is first pre-quenched at 240-480°C, and then sent to a roller press. Steel rolls with high hardness and high smoothness are used for rough rolling, intermediate rolling, and finishing rolling, and the aluminum coil is rolled into thin sheets, and then it is quenched to get aluminum foil. The thickness of the aluminum foil can be controlled by adjusting the tension, the rolling force of the rough rolling, and the speed of the finishing rolling.
