Aluminum foil has been fully integrated into our lives.
In daily life, household foils, container foils, lunch box foils, food foils, flexible packaging foils, foils for high-temperature cooking bags, beer sealing foils, etc. are used in food. There are also medicinal foils, cigarette foils, hairdressing foils, decorative foils for interior walls and interior furniture of buildings, etc. Other application fields include battery foil, battery soft package foil, electronic label foil, circuit board foil, aluminum foil for air-conditioning duct, brazing foil for automobile water tank, composite foil for automobile air-conditioning fin, aluminum foil for radiator, aluminum foil for printing , electronic foil, thermal insulation foil, circuit board foil, cardboard foil, heat sealing foil, etc.; and high-voltage anode foil in aluminum electrolytic capacitors, which are indispensable components of electronic products.
Household aluminum 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. Common specifications: 0.007-0.05mm
The medicinal aluminum foil has the advantages of non-toxicity, corrosion resistance, impermeability, heat resistance, moisture resistance, light resistance, high temperature sterilization, etc. The main uses are the blister packaging of medicine capsules, tablets, etc., as well as the bags of powder granules and water preparations. 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. Status: O, after cold stamping, used for high-grade pharmaceutical packaging; status: H18, after coating, used for ptp medicinal aluminum foil, commonly used thickness: 0.006-0.08mm
Battery aluminum 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 a positive electrode current collector. Common specifications: 0.009-0.1mm
Air conditioner aluminum 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, anti-corrosion inorganic coating and hydrophilic organic coating are applied before forming to form 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.
