What Aluminum Foil Do You Need to Use in Daily Life?

1. Household aluminum foil

Household foils are widely used in cooking, freezing, preservation, baking and other industries. In the refrigerator or freezer, the aluminum foil can be directly wrapped on the food, which can keep the food from being deformed, and can avoid the loss of water from fish, vegetables, fruits, and dishes, and prevent the leakage or mixing of flavors. Since aluminum foil has good and uniform thermal conductivity and heating effect, it can be used in ovens, steamers, etc.

2. Medicinal aluminum foil

Aluminum foil for pharmaceutical packaging is a kind of thin aluminum foil, which has the advantages of non-toxicity, corrosion resistance, impermeability, heat resistance, moisture resistance, light resistance, and high temperature sterilization. Packaging, especially PTP aluminum foil, is moisture-proof, easy to carry, safe and hygienic, and is widely used in the international pharmaceutical industry. The production environment requirements of medicinal aluminum foil processing plants are relatively high, such as requiring no less than 100,000-level purification workshops. Commonly used medicinal foils on the market are available in two alloy states.

3. Battery aluminum foil

Battery foil is one of the base materials of lithium batteries for new energy vehicles. Usually, the lithium ion battery industry uses rolled aluminum foil as the positive electrode current collector.

4. Air conditioner aluminum foil

Air conditioner hydrophilic aluminum foil is a special material for manufacturing heat exchanger fins for air conditioners. The air conditioner foil used in the early days was plain foil. In order to improve the surface properties of plain foil, it is coated with an anti-corrosion inorganic coating and a hydrophilic organic coating before forming to form a hydrophilic foil, which is widely used in household industrial air conditioners, refrigerators, automotive air conditioners and other refrigeration equipment. In addition, there is a hydrophobic foil, which makes the surface of the fins have a hydrophobic function to prevent condensed water from sticking to it. It is mainly used in dryers to improve heating efficiency.

5. Honeycomb aluminum foil

Honeycomb aluminum foil has the advantages of light weight, high strength and high rigidity, and is widely used in the exterior wall decoration of high-rise buildings.

6. Electricity and electrode aluminum foil

After the electronic aluminum foil is processed into foil, it is subjected to surface corrosion treatment and reoxidation treatment, and then wound processing to make capacitors. The aluminum foil before corrosion is called light foil, the aluminum foil after corrosion is called corrosion foil, and the aluminum foil after reoxidation is called finished foil. Electronic aluminum foil refers to the light foil, which is the key raw material for the production of aluminum electrolytic capacitors. The electrode foil includes corrosion foil and chemical foil. Electronic aluminum foil can be divided into high voltage anode foil, low voltage anode foil, negative electrode foil, etc.

7. Flexible packaging aluminum foil

Flexible packaging is a bag-type container made of flexible composite packaging materials. Different processes such as dry lamination, hot melt lamination, and extrusion lamination are used according to the different uses of flexible packaging. Flexible packaging not only has the functions of moisture-proof and fresh-keeping, but also can print various patterns and characters. It is an ideal material for modern commercial packaging.

8. Decorative aluminum foil

Decorative foil is a decorative material applied in the form of aluminum-plastic composite, which utilizes the characteristics of good colorability and high light and heat reflectivity of aluminum foil. Mainly used for construction, furniture decoration and part of gift box packaging. It is generally used as a decorative material for the inner wall of buildings and indoor furniture, and is also widely used in the facade and interior decoration of commercial institutions. Decorative foil has the advantages of heat insulation, moisture resistance, sound insulation, fire resistance and easy cleaning.
