In daily life, aluminum foil products can be seen everywhere. They are moisture-proof, corrosion-resistant, high and low-temperature resistant, good barrier properties, and have many excellent properties. They are widely used in many fields. The following is an introduction to the uses of aluminum foil:
1.Household aluminum foil
Household foils are widely used in cooking, freezing, preservation, baking and other industries. In the refrigerator or freezer, aluminum foil can be wrapped directly on the food to prevent the food from deforming, prevent the loss of water in 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.
2. Medicinal foil
Pharmaceutical foil has the advantages of non-toxic, corrosion-resistant, impermeable, heat-proof, moisture-proof, light-blocking, and high-temperature sterilizability. It is mainly used for blister packaging of pharmaceutical capsules, tablets, etc., and bag packaging of powder granules and aqueous agents. , especially PTP aluminum foil is moisture-proof, easy to carry, safe and hygienic, and is widely used in the international pharmaceutical industry. Medicinal aluminum foil processing plants have relatively high production environment requirements, such as no less than a 100,000-level purification workshop. Common medicinal foils on the market come in two alloy states. State: O, after cold punching, used for high-end pharmaceutical packaging; State: H18, after coating, used for PTP medicinal aluminum foil, the common thickness is: 0.006-0.08mm.
3.Battery foil
Battery foil is one of the base materials of lithium batteries for new energy vehicles. Generally, the lithium-ion battery industry uses rolled aluminum foil as the positive electrode collector. Common specifications: 0.009-0.1mm.
4. Air conditioner foil
Air conditioning foil is a special material for manufacturing heat exchanger fins for air conditioners. The air conditioning foil used in the early days was plain foil. In order to improve the surface properties of the plain foil, an anti-corrosive inorganic coating and a hydrophilic organic coating are applied before forming to form a hydrophilic foil, which is widely used in household industrial air conditioners, refrigeration cabinets, automobile air conditioners and other refrigeration equipment. The thickness of air conditioning foil is 0.07mm~0.2mm. With the development of technology, air conditioning foils have a trend of further thinning.
5.Honeycomb aluminum foil
Honeycomb aluminum foil has the advantages of light weight, high strength, and high rigidity. It is widely used in exterior wall decoration of high-rise buildings. The middle layer of honeycomb aluminum foil contains a large amount of air, which can be soundproof, heat-insulated, waterproof, moisture-proof, thermal insulation, and does not release harmful gases. Commonly used thickness is 0.035-0.08mm.
6. Decorative aluminum foil
Decorative foil is a decorative material applied in the form of aluminum-plastic composite, which takes advantage of the characteristics of aluminum foil with good colorability and high light and heat reflectivity. Mainly used for construction, furniture decoration and some gift box packaging. It is generally used as a decorative material for the inner walls of buildings and indoor furniture, and is also widely used in the facades and interior decoration of commercial institutions. Decorative foil has the advantages of heat insulation, moisture resistance, sound insulation, fire resistance and easy cleaning. Thickness is usually: 0.01-0.2mm.
7.Soft packaging aluminum foil
Flexible packaging is a bag container made of soft 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 be printed with various patterns and text, making it an ideal material for modern commercial packaging. Common specifications: 0.0058-0.03mm.
It is used in fast food restaurants, takeout restaurants, high-end hotels, aviation tableware, home kitchens and other food utensils. It has the characteristics of beautiful appearance, easy use, safety and hygiene, and no odor pollution. Common specifications: 0.01-0.2mm.
9. Smoke foil
Aluminum foil for cigarettes is mainly compounded with paper and used as the inner lining paper of cigarette boxes. The aluminum foil papers used as cigarette lining papers mainly include calendered aluminum foil paper and aluminized paper. The surface of the smoke foil is smooth and traceless, the plate shape is flat, there are few pinholes, 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 preserve the aroma, the aluminum foil paper can prevent the smell of cigarettes from dispersing and prevent the smell of cigarettes from corroding other items; the other is to prevent mildew. Aluminum foil can block moisture and effectively prevent moisture, thereby preventing cigarettes from becoming moldy in humid environments. The thickness is basically 0.0063-0.0065mm.
10. Cable foil
Cable foil is an aluminum-plastic composite foil that takes advantage of the sealing and shielding properties of aluminum foil and is coated with plastic film on one or both sides. It is used as a shield for cables. Cable foil requires less oil on the surface, no holes, and high mechanical properties. The overall quality requirements are not high, but the length requirements are extremely strict. Commonly used thicknesses are: 0.007-0.2mm.
