Industry needs to promote the development of aluminum foil supply

2017-03-15

With the improvement of living standards, people's demand for food and requirements are also getting higher and higher, of course, packaging materials will be a large number of supply, which promotes the growing supply of aluminum foil.

Mechanical properties mainly refers to the tensile strength, elongation and cupping value of aluminum foil. From the use of perspective, hope that the three indicators of the higher the better, and the material itself, the three indexes and contradictory, namely when the tensile strength of the aluminum foil is relatively high, the elongation index will decline; and improve the elongation of aluminum foil, and will cause the tensile strength decreased. Therefore, in practice, the average value of mechanical properties is generally taken, while the specific strength and the plastic value are related to the punching die of the heat exchanger.

Industry needs to promote the development of aluminum foil supply

General heat exchange sheet punching processing is divided into two types of tensile and non tensile. Tensile stamping processing of the mold requires better plasticity of aluminum foil, that is, the elongation rate is relatively high, the relative strength value can be slightly lower; and no tensile mold with the requirements of the strength of aluminum foil, plastic is a secondary indicator. There are many factors that influence the mechanical properties of aluminum foil. On the strength and plasticity of the aluminum foil, by adjusting the chemical composition or change the processing process and parameters, can make the plasticity of material or intensity in a certain range while maintaining a constant under the other party change. That is to say, through the adjustment of chemical composition and processing technology, the strength and plasticity of aluminum foil can be changed.

With the improvement of people's living level and the tourism industry, beer, soft drinks and other beverages and canned food demand is increasing, the need of modern packaging and decoration, in order to facilitate the international market competition. In order to meet the requirements of the market, people have developed a good shielding plastic film and spray foil and other packaging materials, but their overall performance is not as good as the coating and laminating process can be made up and improved. So it can be said that aluminum foil is a variety of excellent performance, more perfect packaging materials, in many areas are fully demonstrated its broad application prospects.

Aluminum foil is a high value-added product in aluminum processing industry. Industry has developed rapidly, the market size and production volume in successive years of strong growth. Because of its excellent performance in the field of heat conduction and recycling, the application of aluminum foil in the appliance, packaging and other aspects has been greatly expanded.
