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

Aluminum foil has been fully integrated into our lives. From thick foil to single-zero foil and double-zero foil, this kind of material with a thickness of no more than 0.2mm contains a lot of energy in a thin piece.

In daily life, household foils, container foils, lunch box foils, food foils, flexible packaging foils, etc. are used in food. In addition to lighting and heating in the kitchen, aluminum foils are commonly used in life as medicine foils, cigarette foils, hairdressing foils, etc. Foils and decorative foils for interior walls of buildings and interior furniture, etc. Other application fields include battery foil, battery soft-pack foil, electronic label foil, etc.; and high-voltage anode foil in aluminum electrolytic capacitors, which are indispensable components of electronic products.

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 water loss of 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. to heat directly on the original packaging.

The medicinal foil has the advantages of non-toxicity, corrosion resistance, impermeability, heat resistance, moisture resistance, light resistance, and high-temperature sterilization. In particular, PTP aluminum foil is moisture-proof, easy to carry, safe and hygienic, and widely used in the international pharmaceutical industry.

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.

Air conditioner foil is a special material for the manufacture of 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. The thickness of the air conditioner foil is 0.07mm~0.2mm. With the development of technology, there is a trend of further thinning of air-conditioning foil.

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

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 the light foil, the aluminum foil after corrosion is called the corrosion foil, and the aluminum foil after reoxidation is called the finished foil.

Electronic aluminum foil refers to 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. Among them, high and low-voltage anode foils (formed foils) need to use more than 99.99% high-purity aluminum.

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.

It is used in fast food restaurants, takeaway speed matching stores, high-end hotels, aviation tableware, home kitchens, and other food utensils. It has the characteristics of beautiful appearance, convenient use, safety and hygiene, and no odor pollution.

The aluminum foil for cigarettes is mainly used as the inner lining paper of the cigarette box after being compounded with paper. The surface of the cigarette foil is smooth and traceless, the plate shape is flat, the pinholes are few, the cost is relatively low, and the chemical properties are relatively stable.

The aluminum foil paper in the cigarette case has two main functions: one is to preserve the fragrance, the aluminum foil paper can prevent the smell of cigarettes from emitting, and at the same time prevent the smell of cigarettes from eroding other items; the other is to prevent mildew. Aluminum foil can block moisture and effectively prevent moisture, so as to avoid mildew on cigarettes in humid environments.

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.

The above briefly introduces the application of aluminum foil in life. If you want to customize or buy aluminum foil, please contact us.
