How thick is aluminum foil?
What is aluminium foil? Aluminum foil is a hot stamping material that is directly rolled into thin sheets with metal aluminum. It has a very thin thickness. Aluminum foil is also called fake silver foil because its hot stamping effect is similar to that of pure silver foil. Aluminum foil has many excellent properties, including soft texture, good ductility, silvery luster, moisture-proof, airtight, light-shielding, abrasion-resistant, non-toxic and odorless. These characteristics make aluminum foil widely used in many industries.
Is aluminum foil thick? Aluminum foil can have a very thick thickness after being rolled out of materials such as aluminum plates. The thickness of aluminum foil can vary greatly depending on its specific application and needs. Generally speaking, the thickness of aluminum foil can range from a few microns (μm) to a few millimeters (mm), and the common thickness range is 0.005-0.8mm.
What is the thickness of standard foil?The thickness of standard aluminum foil is not a fixed value, but varies according to the specific use and specifications. The thickness of standard aluminum foil is usually between 0.01-0.02 mm (10-20 microns). Household aluminum foil used in the kitchen is generally around 0.016 mm (16 microns), while the thickness of industrial aluminum foil may be larger or smaller, depending on the specific use. Huawei Aluminum Foil Factory can provide aluminum foils of various thickness specifications within the standard range.
Ultra-thin aluminum foil: The thickness is usually less than 10 microns, such as 6 microns, 8 microns, etc. This extremely thin aluminum foil has important applications in the electronics industry, such as capacitors, electrode materials for lithium batteries, electromagnetic shielding, etc. At the same time, in the field of food packaging, ultra-thin aluminum foil is also used to improve the barrier properties and aesthetics of packaging.
Thin aluminum foil: The thickness is between 0.01mm and 0.1mm. This thickness of aluminum foil is widely used in food packaging, pharmaceutical packaging, cosmetic packaging and other fields. Thin aluminum foil can provide good barrier properties, freshness preservation and aesthetics, and is a common material in the packaging industry.
Medium-thick aluminum foil: The thickness ranges from 0.1mm to several millimeters. Aluminum foil of this thickness has important applications in construction, industry, aerospace and other fields. For example, in the construction field, medium-thick aluminum foil can be used as thermal insulation material; in the industrial field, medium-thick aluminum foil can be used as an anti-corrosion protective layer for pipelines and equipment.
Thick aluminum foil: Aluminum foil with a thickness of more than several millimeters. This thickness of aluminum foil is relatively rare, but it is still needed in some specific applications. For example, some industrial equipment or containers may need to use thick aluminum foil as a structural material or protective layer.
Aluminum foil has the characteristics of corrosion resistance and good tensile strength. It is an excellent material for packaging. Common packaging scenarios include food packaging and pharmaceutical packaging.
Aluminum foil composite film: The thickness selection is usually determined according to specific packaging needs. For example, aluminum foil composite film of about 0.08mm is suitable for food packaging and can provide good protection and barrier properties. Tin foil: Its thickness ranges from 0.006mm to 0.1mm, and it is also commonly used for food packaging, such as candy and chocolate packaging.
Foil cover foil in blister packaging: The thickness ranges from 0.36mm to 0.76mm, but 0.46mm to 0.61mm is the most common preferred range. These foil cover foils are generally used to protect pharmaceuticals from environmental factors and ensure the safety and effectiveness of pharmaceuticals. Specific regional differences: In most countries outside the United States, the commonly used aluminum cover foil thickness is 20µm (i.e. 0.02mm), while 17µm aluminum cover foil is used in Japan. In Europe, 20µm and 25µm aluminum foils are used in dense foil blister packaging with similar effects, and neither affects its barrier properties.
6-micron aluminum foil is the thinnest type of aluminum foil, commonly used in capacitors, lithium batteries and other fields. Due to its extremely thin thickness, it can improve the energy density and performance stability of the device.
7-micron aluminum foil is commonly used in daily household life such as baking tray liners and oven insulation pads. It has good thermal insulation and high temperature resistance and can effectively protect food and home appliances.
9-micron aluminum foil is the most common thickness and is widely used in food packaging, pharmaceutical packaging and other fields. Due to its good moisture resistance and sealing performance, it can effectively protect food and medicine from the influence of the external environment.
11-micron aluminum foil is commonly used in oven insulation pads, automotive sound insulation materials and other fields. It has good thermal insulation and noise prevention effects, which can improve the comfort and safety of the car.
18-micron aluminum foil is commonly used in building insulation materials, air conditioning ducts and other fields. Due to its good fire resistance and corrosion resistance, it can improve the safety and service life of buildings.
25 micron aluminum foil is usually used in electronic products, printing industry and other fields. Due to its good conductivity and printability, it can be used to manufacture capacitors, printed circuit boards and other products.
40 micron aluminum foil is usually used in aerospace, military and other fields. Due to its thick thickness and good corrosion resistance, it can be used to manufacture aircraft parts, missile shells and other products.
