What are the characteristics of aluminum foil and aluminum foil, what is the difference?
Moreover, heating and open package is very convenient, welcomed by consumers. With the improvement of people's living level and tourism the 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 recent years, in order to meet the market demand, people developed a good shielding plastic film and spray plating foil packaging material, but the comprehensive performance they are not as good as a coating and laminating process can get up and improved. Therefore, the foil is has many excellent properties, packaging materials more perfect, in many fields are fully demonstrated its wide application before King. In order to improve the quality and efficiency of rolling aluminum foil products, modern aluminum foil mill to the development of large, wide, high speed and automation in four directions. Modern 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 the thickness control system (AGC), most of the installation of shapemeter (AFC). The aluminum foil industry is facing a period of rapid development.
As the decoration of the gold and silver thread, wallpaper and all kinds of stationery printing and packaging trademark of light industrial products and so on. All the above purpose, 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 so, 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 shielding the performance of water vapor, air, ultraviolet radiation and bacteria and other necessary packaging materials, greatly expand the application market. Due to aluminum foil packaged goods and outside light, humidity, gas filled Isolated, so that the packaging has been well protected. Especially for cooking food packaging, the use of this composite foil material, at least can ensure food for more than a year without deterioration.
X B pinyin is coated with a thin layer of tin paper, multiple folded or paste into the ingot shaped, superstitious people used to give a ghost incineration. Aluminum foil aluminum rolled into sheets of hot stamping material, the effect of stamping and silver foil stamping similar effects, so it is also called false because of silver. Aluminum soft texture, good ductility, with silver white luster, if after rolling sheet made of aluminum foil in the offset paper with a sodium silicate material mounted, can also be printed. But the foil itself easy oxidation and dark, friction, touch will fade, so it can not be used to save Yu Changjiu the book covers the hot stamping foil. Because of its excellent characteristics, widely used in packaging materials, food and beverages, cigarettes, drugs, daily necessities, household photographic plates; electrolytic capacitor materials; thermal insulation materials for building, vehicle, ship, etc. housing can also;
