What is thick aluminum foil?

Thick aluminum foil is a type of aluminum foil that is thicker and heavier than the standard aluminum foil commonly used in kitchens and homes. It is designed for more rugged applications where durability and heat resistance are important. Standard aluminum foil is typically about 0.016 厚さ mm, while thick aluminum foil can range from 0.02 に 0.05 mm or even thicker.

Thickness range of thick aluminum foil

The thickness of thick aluminum foil is generally 100-200microns (100 μm-200 μm). Thick aluminum foil is usually used in industrial fields, such as power capacitors, gas storage tanks, 等. Its high thickness and strength can meet the needs of large equipment, and it also has good anti-corrosion and barrier properties.

Aluminum foil thickness types

種類	厚さ	特徴
Ultra-thin aluminum foil	10 micron-30 micron	Ultra-thin aluminum foil has high flexibility and ductility and is often used in the packaging of capacitors, batteries and other products in the electronics industry. Due to its good shielding and conductive properties, ultra-thin aluminum foil can also be used for electromagnetic shielding and heat conduction and heat dissipation of electronic products.
Thin aluminum foil	30 micron-60 micron	Compared with ultra-thin aluminum foil, thin aluminum foil has better strength and corrosion resistance. Thin aluminum foil is widely used in the food packaging industry, such as packaging chocolate, milk powder, coffee, 等. It can effectively protect the freshness and nutrients of food. 加えて, thin aluminum foil is also widely used in fields such as cigarette packaging and pharmaceutical packaging.
Medium thickness aluminum foil	60 micron-100 micron	Medium thickness aluminum foil is superior in strength and corrosion resistance and is commonly used in construction, home appliances and other fields. In the construction sector, medium-thickness aluminum foil is commonly used for roof insulation, moisture protection and thermal insulation. In the home appliance industry, aluminum foil is usually used as a thermal conductive sheet in refrigerators, air conditioners and other equipment to improve heat dissipation.

Application range of thick aluminum foil

Aluminum foil is widely used in various industries due to its lightness, strong plasticity, and good barrier properties.

1-食品包装
Aluminum foil is widely used in the 食品包装 industry, such as chocolate, milk powder, coffee, 等. It can effectively protect food from oxygen, 水分, light and odor, extending the shelf life of food. 同時に, aluminum foil can also prevent mutual contamination between food and packaging materials.

2 電気製品
Aluminum foil is also widely used in electronic products. Ultra-thin aluminum foil is often used for packaging capacitors, batteries and other products, and has good thermal conductivity and electromagnetic shielding properties. 加えて, aluminum foil is also used in shielding covers for mobile phones, TVs and other equipment to reduce external interference.

3建築資材
Aluminum foil of medium thickness is commonly used in the construction sector for roof insulation, moisture protection and thermal insulation. It can effectively block the transfer of heat and moisture and maintain indoor comfort. 加えて, aluminum foil can also be used as exterior wall insulation material to improve the energy-saving performance of buildings.
