Copper and aluminum used for electronic components fixed, welding, casing protection and electromagnetic protection, copper foil, aluminum foil, copper foil and insulating sheet combination we can provide various shapes according to the requirements, and the back glue.
Aluminum foil because of its excellent characteristics, widely used in food, beverages, cigarettes, drugs, daily necessities, household photographic plate, usually used as packaging materials; electrolytic capacitor materials; thermal insulation materials for building, vehicle, ship and housing; also can be used as a decorative silver line, wallpaper and all kinds of stationery printing and light industry the decoration of trademark products. In these applications, can most effectively play as foil performance point of packaging materials. Aluminum foil is soft metal film, not only has the advantages of moisture, air tightness, shading, abrasion and aroma, non-toxic and tasteless, but also because of its elegant silvery white luster, easy to produce all sorts of color beautiful designs and patterns, which is more likely to be favored by people. Especially the aluminum foil and plastic and paper composite, the shield and the strength of paper, plastic aluminum foil heat seal which further improves as the shielding performance of water vapor, air, ultraviolet radiation and bacteria and other necessary packaging materials, greatly broaden the aluminum foil application market. The packaging of goods and outside light, wet gas, fully isolated, so that the package has been well protected. Especially for cooking food packaging, the use of this composite aluminum foil material, at least can ensure food for more than one year is not bad. Moreover, heating and open the package is very convenient, welcomed by consumers.
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 market demand, people developed a good shielding plastic film and spray plating foil packaging materials, but they are not as good as a comprehensive performance of coating and laminating processing can get up and to improve. It can be said that the aluminum foil is has many excellent properties, packaging materials more perfect, in many fields have fully demonstrated its wide application prospects.
In order to improve the efficiency and quality of rolled aluminium products, modern aluminum foil mill to the development of large, wide, high speed and automation in four directions. The aluminum foil mill roll width has reached more than 2200mm, the rolling speed can reach more than 2000m/min, the volume reached 20T. The automation level of rolling mill is improved greatly, generally installed thickness control system (AGC), most of the installation of shapemeter (AFC). The aluminium foil industry is facing a period of rapid development.
The aluminum foil with clean, sanitary and shiny appearance, it can be used with many other packaging materials made of integrated packaging materials, and the surface of the aluminum foil printing effect than other materials are good, in addition there are several characteristics of aluminum foil:
(1) aluminum foil surface is very clean and sanitary, no bacteria or microorganisms can grow on the surface.
(2) aluminum foil packaging materials is a non-toxic, it can be in direct contact with food without any harm to the health of human suffering.
(3) aluminum foil as a packing material, odorless, does not make any odor of food packaging.
(4) if the volatile foil itself is not, itself and the packaging of food will not dry or shrink.
(5) in high temperature or at low temperature, aluminum foil will not have occurred the phenomenon of oil penetration.
(6) aluminum foil as a packaging material is not transparent, so the sunlight irradiation products such as margarine and other packaging materials is a kind of very good.
(7) the aluminum foil with good plasticity, so it can be used for packing all kinds of products. It can be caused by various container.
(8) aluminum foil with high hardness, tensile strength and tear strength, but its small, so easily torn.
(9) foil itself to heat sealing, must be applied on the surface of the heat resistance of the materials, such as PE to heat sealing.
(10) aluminum foil and other heavy metals or heavy metal contact, may have adverse reaction.
