From thick foil to single zero foil and double zero foil, this material with a thickness of no more than 0.2mm is widely used in daily life. There are household foils, container foils, lunch box foils, food foils, flexible packaging foils, beer sealing foils, etc. used in food. In addition to the kitchen, aluminum foil is commonly used in life, such as medicinal foil, cigarette foil, hairdressing foil and decorative foil. Other application fields include battery foil, battery soft package foil, electronic label foil, circuit board foil, air-conditioning duct foil, brazing foil, automotive air-conditioning fin foil, aluminum foil for radiator, printing foil, electronic foil, thermal insulation foil, Circuit board foil, cardboard foil, heat sealing foil, electronic foil, etc.
- Household foil
Common thickness: 0.007-0.05mm
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. to heat directly on the original packaging.
- Medicine foil
Common thickness: 0.006-0.08mm
The medicinal foil has the advantages of non-toxicity, corrosion resistance, impermeability, heat resistance, moisture resistance, light resistance, and high temperature sterilization. The main uses are the blister packaging of drug capsules, tablets, etc., as well as the bag packaging of powder granules and water preparations, especially PTP aluminum foil is moisture-proof, easy to carry, safe and hygienic, and is widely used in the international pharmaceutical industry.
- Battery foil
Common thickness: 0.009-0.1mm
Battery foil is one of the base materials of lithium battery for new energy vehicles. Usually, the lithium ion battery industry uses rolled aluminum foil as the positive electrode current collector.
- Air conditioning foil
Common thickness: 0.07mm~0.2mm.
Air conditioning 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.
- Electronic foil
High-voltage anode foil: 0.0065-0.11mm
low-voltage anode foil: 0.04-0.1mm
After the electronic aluminum foil is processed into foil, it is subjected to surface corrosion treatment and reoxidation treatment, and then is wound to form a capacitor. 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 need to use more than 99.99% high-purity aluminum.
- Flexible packaging foil
Common specifications: 0.0058-0.03mm
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.
- Container foil
Common specifications: 0.01-0.2mm
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.
- Cigarette foil
Common specifications: 0.0063-0.0065mm.
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: The aluminum foil paper can prevent the smell of cigarettes from emitting, and at the same time avoid the smell of cigarettes from eroding other items; Anti-mildew, aluminum foil paper can block moisture and effectively prevent moisture, so as to avoid mildew of cigarettes in humid environment.
- Cable foil
Common thickness: 0.007-0.2mm
The cable foil is an aluminum-plastic composite foil formed by using the airtightness and shielding properties of the aluminum foil and coated with plastic film on one or both sides, which is used as a shield for the cable. The cable foil requires less oil on the surface, no holes, and high mechanical properties.
- Decorative foil
Common thickness: 0.01-0.2mm
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. Decorative foil has the advantages of heat insulation, moisture resistance, sound insulation, fire resistance and easy cleaning.
