The State Of The Foil
Jun 09, 2017

Aluminum foil is a metal foil directly into a sheet of hot stamping material, the hot stamping effect and the effect of pure silver foil stamping, Aluminum Foil it is also known as false silver foil. As the aluminum texture is soft, good ductility, with silver-white luster, if the calendering after the film, with sodium silicate and other substances mounted on the offset paper made of aluminum foil, but also for printing. But the foil itself is easy to oxidize and darken the color, friction, touch and so will fade, it is not suitable for long-term preservation of the book cover and other hot stamping.

Aluminum foil because of its excellent characteristics, widely used in food, beverages, cigarettes, drugs, photographic floor, household necessities, etc., usually used as packaging materials; electrolytic capacitor materials; construction, vehicles, ships, houses and other insulation materials; As the decoration of the gold and silver lines, wallpaper and all kinds of stationery prints and light industrial products, such as decorating trademarks. In the above-mentioned various applications, the most effective use of aluminum foil performance point is as a packaging material. Aluminum foil is a soft metal film, not only has moisture, airtight, shading, Aluminum Foil abrasion resistance, fragrance, non-toxic and tasteless advantages, but also because of its elegant silver white luster, easy to process a variety of colors and beautiful patterns Patterns, and thus more vulnerable to people

Foil tape

In particular, aluminum foil and plastic and paper composite, the aluminum foil shielding and paper strength, plastic heat sealing properties, and further improve the packaging materials necessary for water vapor, air, ultraviolet and bacteria shielding performance , Greatly broaden the application of aluminum foil market. As the packaging of goods and the outside world of light, wet, gas and other fully isolated, so that the packaging has been well protected. Especially for the packaging of cooked food, the use of this composite aluminum foil material, Aluminum Foil at least to ensure that food for more than a year without deterioration. Moreover, heating and opening are very convenient, well received by consumers.

With the improvement of people's living standards and the development of tourism, beer, soft drinks and other beverages and canned food demand is increasing, these need to have a modern packaging and decoration, in order to facilitate competition in the international market. In order to meet the market requirements, people have developed a good shielding of plastic film and spray foil and other packaging materials, but their overall performance are better than the coating and laminated processing can be made up and improved. Aluminum Foil 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 according to the state can be divided into hard foil, semi-hard foil and soft foil.

① hard foil: after rolling without softening (annealing) of the aluminum foil, without degreasing treatment, the surface of the cloth there are poor. Therefore, hard foil in the printing, bonding, Aluminum Foil coating must be defatted before treatment, if used for forming can be used directly.

② semi-hard foil: aluminum foil hardness (or strength) between the rigid foil and soft foil foil, usually used for forming processing.

③ soft foil: after rolling through the full annealing and soften the aluminum foil, soft material, the surface without residual oil. Most applications, such as packaging, composite, electrical materials, etc., use soft foil.
