What aluminum foil is needed in daily life?

West Aluminum - West Aluminum Industry Telecom: From thick foil to single zero foil and double zero foil, this kind of material with thickness of less than 0.2mm has great energy, which can last up to nine days and go down to five seas. In daily life, there are household foil, container foil, lunch box foil, food foil, soft packaging foil, high temperature cooking bag foil, Tetra Pak / Kangmei wrapping foil, beer sealing foil, etc. in addition to lighting and heating in the kitchen, aluminum foil is commonly used in daily life, such as medicine foil, cigarette foil, hair care foil and decorative foil of building inner wall and interior furniture. Other application fields include battery foil, battery soft package foil, electronic label foil, circuit board foil, air conditioning duct aluminum foil, automobile water tank brazing foil, automotive air conditioning fin composite foil, radiator aluminum foil, printing aluminum foil, electronic foil, heat preservation foil, circuit board foil, card paper foil, heat sealing foil, etc.; and the aluminum electrolytic capacitor, which is indispensable for electronic products, is high Pressure anode foil, etc.

Household foil

Household foil is widely used in cooking, freezing, preservation, baking and other industries. In the refrigerator or freezer, aluminum foil can be directly wrapped on the food, which can keep the food from deformation, and avoid the water loss of fish, vegetables, fruits and dishes, and prevent the leakage or mixing of flavor. Due to its good and uniform thermal conductivity and heating effect, aluminum foil can be used to heat directly on the original package in oven and steamer. Common specification: 0.007-0.05mm

Medicinal foil

Drug foil has the advantages of non-toxic, corrosion-resistant, impermeable, heat-resistant, moisture-proof, light-resistant, high-temperature sterilization and other advantages. It is mainly used for blister packaging of drug capsules and tablets, and bag packaging of powder particles and water agents, especially PTP aluminum foil, which is moisture-proof, convenient to carry, safe and hygienic, and is widely used in the international pharmaceutical industry. Pharmaceutical aluminum foil processing plant production environment requirements are relatively high, such as the requirements of no less than 100000 purification workshop. There are two kinds of alloy state in common medicine foil on the market. State: O, after cold stamping, used for high-grade medical packaging; state: h18, after coating, used for PTP medical aluminum foil, the common thickness is 0.006-0.08mm

Battery foil

Battery foil is one of the base materials of lithium batteries for new energy vehicles. Generally, rolled aluminum foil is used as positive collector in lithium-ion battery industry. Common specification: 0.009-0.1mm

Air conditioning foil

Air conditioning foil is a special material for manufacturing fin of heat exchanger for air conditioner. The air conditioner foil used in the early days was plain foil. In order to improve the surface properties of plain foil, anticorrosive inorganic coating and hydrophilic organic coating are coated before forming to form hydrophilic foil, which is widely used in household industrial air conditioner, refrigerator, automobile air conditioner and other refrigeration equipment. In addition, there is a hydrophobic foil, which can make the surface of fin hydrophobic and prevent condensation from adhering. It is mainly used in dryers to improve heating efficiency. The thickness of air conditioning foil is 0.07mm ~ 0.2mm. With the development of technology, air conditioning foil has the trend of further thinning.

Honeycomb aluminum foil

Honeycomb aluminum foil has the advantages of light weight, high strength and high stiffness, which is widely used in exterior wall decoration of high-rise buildings. The interlayer of honeycomb aluminum foil contains a lot of air, which can be used for sound insulation, heat insulation, waterproof, moisture-proof, thermal insulation and no harmful gas release. The common thickness is 0.035-0.08mm

Electronic / electrode foil

After being processed into foil, the electronic aluminum foil is subjected to surface corrosion treatment and reoxidation treatment, and then wound 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 optical foil, which is the key raw material for aluminum electrolytic capacitor production. The electrode foil includes corrosion foil and formed foil. Electronic aluminum foil can be divided into high voltage anode foil, low voltage anode foil and negative electrode foil. Among them, 99.99% high purity aluminum is needed for high and low voltage anode foils. The thickness of high voltage anode foil is 0.0065-0.11mm, and that of low-voltage anode foil is 0.04-0.1mm

Flexible packaging foil

Flexible packaging is a bag type container made of flexible composite packaging materials. According to the different uses of flexible packaging, different processes such as dry composite, hot-melt composite and extrusion composite are adopted. Flexible packaging is not only moisture-proof and fresh-keeping, but also can print various patterns and characters. It is an ideal material for modern commercial packaging. Common specification: 0.0058-0.03mm

Container foil

It can be used in fast food restaurants, take out fast food restaurants, high-grade hotels, aviation tableware, family kitchen and other food utensils. It has the characteristics of beautiful appearance, convenient use, safety and health, and no odor pollution. Common specification: 0.01-0.2mm

Tobacco leaf

Aluminum foil for cigarette is mainly used as inner lining paper of cigarette box after compounding with paper. The aluminum foil paper used as cigarette lining paper mainly includes calendered aluminum foil paper and aluminized paper. The surface of the tobacco foil is smooth without trace, the board shape is flat, the pinholes are few, and the cost is relatively low, and the chemical properties are relatively stable. The aluminum foil paper inside the cigarette box has two main functions: one is to keep the fragrance. The aluminum foil paper can prevent the cigarette flavor from emitting and at the same time prevent the cigarette flavor from eroding other articles; the other is to prevent mildew. Aluminum foil paper can prevent moisture and effectively prevent cigarette from mildew in humid environment. The thickness is 0.0063-0.0065mm.

Cable foil

Cable foil is a kind of aluminum plastic composite foil, which is made up of aluminum foil, which is coated with plastic film on one side or both sides, and is used as the shield of cable. The cable foil requires less oil on the surface, no holes and high mechanical properties. The overall quality requirement is not high, but the length requirement is very strict. The common thickness is 0.007-0.2mm

Decorative foil

Decorative foil is a kind of decorative material applied in the form of aluminum plastic composite, which takes advantage of the good coloration and high light and thermal reflectance of aluminum foil. It is mainly used for decoration of architecture and furniture and packaging of some gift boxes. Generally, as the decoration material of building inner wall and interior furniture, it is also widely used in the facade and interior decoration of commercial organizations. Decorative foil has the advantages of heat insulation, moisture resistance, sound insulation, fire prevention and easy cleaning. The thickness is usually 0.01-0.2mm
