aluminum foil is ductile. Foil can be rolled to only 0.007 mm thickness, but will still be completely impermeable and lets neither light, aroma nor taste substances in or out. The metal itself forms a protective oxide coating and is highly corrosion resistant. Different types of surface treatment can further improve these properties
Aluminum is a pretty good conductor. For a while it was competing with copper for wiring in home construction though safety concerns arose. Concerning aluminum foil, its thinness is an issue since the cross section of a conductor impacts electrical resistance. If you take a thin strip of Al foil and attach a dry cell battery, you will find it rapidly heats and then combusts.
The soft pack battery is made of 8021 alloy aluminum foil 0.04mm thickness, and there are other aluminum foils (1235/1060/1070 pure aluminum 0.012-0.016mm thickness). The product is widely used in electric bicycles, electric vehicles, power tools, electric toys, solar photo voltaic power generation systems, cigarette lighter power supplies, emergency lighting, portable power sources and mine safety equipment
The main difference between them is that the melting point of aluminum foil is higher than that of tin foil paper and is more suitable for barbecue food.
Carbon coated aluminum foil is kind of the aluminum foil that evenly coated with current-conducting nano-graphite and carbon particle. The carbon coated aluminum foil owns an excellent static electric conductivity, it can collect the micro-current of active substance, it is not only to significantly reduce the contact resistance between the positive / negative electrode material and the collector, but also increase the adhesive ability between both of them, thus to reduce the amount of binder and improve overall performance of the battery.
Its 8021 prime aluminum foil material has good extensible. The main advantages are often used in deep-drawn packaging materials. The special properties of 1235/1060/1070 with high conductivity are also commonly used in the inner core of electronic products.
At present, China consumes 161,300 tons of aluminum foil each year and has become the second largest consumer of aluminum foil in the world after the United States. However, there is still a big gap between per capita possession and developed countries, especially the amount of aluminum foil tape used for packaging Limited, has a broad space for development. Widely used in cigarettes, medicines, beverages, food, camera floor, household items and so on. Aluminum foil is a soft metal film, not only has moisture, airtight, shading, erosion-resistant, Paul Hong, non-toxic and tasteless, but also because of its elegant silver-white luster, easy to process a variety of colors and beautiful patterns and Pattern, which is more susceptible to people’s favor. With the rapid rise of the packaging industry, after decades of development, China’s metal tape gradually occupy a strong position in the market.
There may be several reasons why you would want to harden aluminum foil. A sculpture made of aluminum foil can be fragile and you may wish to make it more substantial to last longer. Aluminum foil can also be used as an exterior cover for pipe insulation. Heating and cooling pipes are wrapped with insulation to eliminate condensation and to provide a more consistent internal temperature. Aluminum foil is a very good insulator.
The ice cream packaging not only play an important role in brand, as well as in quality. The packaging of cased ice cream chiefly are carton, plastic box and aluminum foil box. The carton have been long used in ice cream, and still exist in the market now. Carton is coated with wax or a mixture of polyethylene and wax, it aims to improve the strength and moisture resistance, and usually enclose with a wood spoon. The carton packaging does not polluted the environment, is convenient and economical, but its strength is not strong enough, and easy to deformed.
The bottle cap is an important part of the packaging, and it is also the place where consumers first come in contact with the product. The safe and beautiful appearance of the bottle cap is very important. The aluminum bottle cap has the characteristics of maintaining the product’s tightness and stable quality, and also has the functions of anti-theft opening and safety. Therefore, the aluminum bottle cap is widely used in aluminum foil for cosmetic bottle caps, aluminum for easy-open bottle caps, and aluminum for wine caps. Medical caps such as aluminum.
