Packing with aluminum foil consumption is more and more popular, this is because it has a series of excellent function.
The packaging aluminum are mainly including pure aluminum, aluminum alloy and aluminum foil:
The use of aluminum packaging, because the aluminum plate containing more than 99.9% aluminum, the thickness is usually between 0.25 ~ 0.3mm. It is soft, low strength, so less use it for packaging materials, but also useful for alcohol containers.
Aluminum alloy is a small increase in aluminum magnesium, manganese, copper alloy formed by processing. Packaging aluminum commonly used in aluminum-magnesium alloy and aluminum-manganese alloy, also known as rust-proof aluminum alloy. Alloy aluminum plate strength and hardness improved significantly, corrosion-resistant features, polishing is good, long-term preservation of the surface is still adhere to bright.
Aluminum alloy packaging used in the market for the manufacture of canned containers for fish and meat cans, tin will not occur as sulfurized tin black appearance; more of a packaged beverage, will not make the drinks appear muddy and Flavor change and so on.
Aluminum foil for aluminum packaging
Aluminum foil sale for packaging is also very common, aluminum foil is pure purity of 99.5% or more made by the rolling, the thickness of 0.005 ~ 0.2mm between. It is light and shiny, reflective ability, can be used for thermal insulation packaging; good barrier, gas and water vapor; easy processing, simple processing into a variety of shapes; easy to print, glue, paint, color , Embossing, printing, etc .; on the temperature adaptability, high temperature or low temperature shape stability; shading, excellent fragrance and so on. The biggest drawback of aluminum foil is not acid and alkali, can not be welded, tear strength is low.
The density of aluminum is small, only about one-third of steel, weight is lighter;Have excellent workability, easy to punch into the shape of a variety of mixed and disorderly;Corrosion resistance is strong, will not rust;Barrier property, shading, fragrance is wonderful, can effectively maintain commodity;High thermal conductivity and convenient for aluminium cans and sterilization;A silvery white, colour and lustre is beautiful, and light reflectivity is big, easy to print, print effect is good;Avirulent insipidity, not because of aluminum ion transgression and bring food in peculiar smell;Aluminium scrap container can recover the remelting, no environmental pollution, etc.So packing aluminium market more and more prosperous.
