18 mic pharma aluminum foil
18 mic medicinal aluminum foil is a metal material with many characteristics such as lightness, easy processing, corrosion resistance, and good air tightness. Therefore, aluminum foil 18 mic is widely used in pharmaceutical packaging. The thickness range of aluminum foil commonly used for pharmaceutical packaging materials is generally between 0.006-0.06 mm. Aluminum foil with a thickness of 18mic (0.018mm) is a commonly used pharmaceutical packaging material.
Aluminum foil used in pharmaceutical packaging 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., as well as powder granules, and liquids. Bag 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 of Huawei‘s medicinal aluminum foil processing plant requires a purification workshop of no less than 100,000 levels and a professional production team.
Common medicinal foils on the market come in two alloy states.
Temper: O, after cold punching, used for high-end pharmaceutical packaging;
Temper: H18, after coating, used for ptp medicinal aluminum foil.
The common thickness of medicinal aluminum foil is: 0.006-0.08mm.
Common alloys: 8011 aluminum foil, 8021 aluminum foil, 8079 aluminum foil, and 1235 aluminum foil.
The thickness of aluminum foil determines the type and performance that can be applied. 18-micron aluminum foil has good performance in medicinal applications and can also be used in other products.
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 keep 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.
Battery aluminum 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.
Air conditioning aluminum 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-corrosion 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. There is also a hydrophobic foil that makes the surface of the fins hydrophobic to prevent condensation water from adhering. It is mainly used in dryers to improve heating efficiency.
The thickness of air conditioning foil is 0.07mm~0.2mm.
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.
Electronic/Electrode Aluminum Foil
After the aluminum material is processed into foil, the electronic aluminum foil undergoes surface corrosion treatment and re-oxidation treatment, and then is wound to make a capacitor. The aluminum foil before corrosion is called light foil, the aluminum foil after corrosion is called corrosion foil, and the aluminum foil after re-oxidation is called finished foil. Electronic aluminum foil refers to light foil and is a 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 (formation foils) require more than 99.99% high-purity aluminum.
The thickness of high-voltage anode foil is 0.0065-0.11mm, and the thickness of low-voltage anode foil is 0.04~0.1mm
Flexible 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.
Container aluminum foil
It is used in food utensils such as fast food restaurants, takeout restaurants, high-end hotels, aviation tableware, home kitchens, etc. It has the characteristics of beautiful appearance, easy use, safety and hygiene, and no odor pollution.
Common specifications: 0.01-0.2mm.
Cigarette foil (cigarette aluminum 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 in 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.
Cable aluminum 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.
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.
