Aluminum material is a kind of rich white light metal, this metal has good chemical and physical characteristics, papel alumínio made from aluminum raw materials also has good characteristics, the world’s aluminum output is second only to steel. Aluminum is most commonly used as a packaging material, its application in the packaging industry in the non-ferrous metals accounted for the first. When used for packaging, aluminum is usually processed into the aluminum plate, aluminum block, papel alumínio, and aluminum film. These types of primary processing materials use is different, the aluminum plate is usually used as canning materials or cover materials; Aluminum blocks are generally used to make extruded and thinned drawing cans;

Aluminum foil is generally used as pharmaceutical packaging material, used to do moisture-proof inner packaging or make composite materials and flexible packaging. In the production of these primary processing materials, packaging plates are rust-resistant aluminum alloy, will be added to manganese and magnesium metal, through this way can improve the material strength, improve processing performance, and other functions.

Not all metals can be processed as alloys, although smelting with other metals can improve some aspects of aluminum. Por exemplo, copper can also improve the strength of the material, but it also has a bad effect. After joining, it will reduce the corrosion resistance and processing performance of the product. While adding zinc, this way will make its heat treatment effect becomes better but accompanied by corrosion resistance and processing will decrease; According to the different scenarios to be applied, the processing of metal also has different requirements, such as aluminum foil in the use of the thickness is very thin, the metal ductility requirements are more strict, usually by the thickness of 0.4-0.7mm (more with 0.5mm) industrial pure aluminum plate after many times of cold rolling thin.

Aluminum material has been rapidly developed and applied around the world, on the one hand, it is rich in resources, on the other hand, it is due to the excellent material characteristics of aluminum metal. Aluminum material has many advantages: the density of aluminum is very small, 2.7g/cm³, only 35‰ of steel, which can reduce the weight of some processed materials and realize the lightweight of the material. And the surface of aluminum can generate a layer of dense aluminum oxide protection film under natural conditions, this layer of colorless film can prevent further oxidation, protection aluminum products will not be easily oxidized corrosion; Aluminum is the first choice for many pharmaceutical packaging materials. Aluminum itself is non-toxic and tasteless, even if it is used to package food, it fully meets the health standards, and will not cause any harm to human body.

Take the medical aluminum foil as an example, after processing, aluminum foil surface gloss is high, easy to color, the drug packaging used in the field will be printed with drug instructions, and the aluminum foil printing effect is very good, far more than other metals; Além disso, aluminum has excellent reflection and conduction properties of light and heat, which can protect drugs from the influence of light.

The mechanical properties of aluminum can remain stable for a long time at low temperatures. As a pharmaceutical packaging material, aluminum foil can also protect the stability of some drugs that need to be preserved at low temperatures. For some special drugs, the composite film made of aluminum foil can be completely impervious to air and light, which can effectively protect the drug inside. Aluminum foil can also improve the strength of the aluminum-plastic composite film. Because aluminum material can be used repeatedly, some waste can be recycled, processed, and reused, which can not only save energy but also prevent the public harm caused by waste and meet the requirements of environmental protection.

Everything has two sides, aluminum products are the same, although aluminum material has a good texture, there are some shortcomings, por exemplo, the production of aluminum is relatively close to the energy consumption, so the price is more expensive than iron; Além disso, aluminum is a non-magnetic material, so some of the use of magnetic absorbing raw material equipment must be not suitable for aluminum products; Aluminum material to acid, alkaline resistance of these substances is poor;

But as technology improves, one-way aluminum products, such as medical foil, can be combined with other materials to compensate for some of its shortcomings. Por exemplo, aluminum foil and paper or plastic composite can increase the stiffness and tensile strength of aluminum products, the ductility of aluminum foil has also been greatly improved.
