Aluminum Foil For Production Flexible Facing
Which side of the aluminum foil is the front side? Why is it designed like this?
Regarding the smooth and matte surface of aluminum foil, it is related to the rolling process of aluminum foil production. Because the aluminum foil is very thin, it is easy to peel off during the production of a single sheet, so it is usually double-rolled (two sheets of the same thickness are stacked together). The surface directly in contact with the working roll of the rolling mill will be very smooth, and the other side is two-sided. The aluminum foil pieces touch each other on the frosted surface. Which side is the front? In fact, from a hygienic point of view, the cleanliness of the two sides is the same, because the two sides are in close contact with each other after being rolled up during the production process, so you can use which side you want to use, depending on your liking.
Aluminum foil is a metal, why can it be widely used in our lives and the price is low?
Economically, aluminum production mainly relies on electrolysis, which consumes approximately 13,000 kilowatt-hours of electricity per ton of aluminum. The current aluminum price is around 14,000 yuan/ton.
In terms of resources, the content of aluminum in the earth's crust ranks first in terms of metal content: aluminum, iron, calcium, sodium, potassium, magnesium, titanium...
In terms of performance, aluminum has very good ductility and has a self-passivation function. Generally speaking, it can be made very thin without rusting.
What else can aluminum foil be used for besides baking? Aluminum foil paper can also be used for printing. So when you encounter aluminum foil paper in printing, how should it be pre-printed?
When the aluminum foil paper is placed in the air, a very thin and dense oxide layer will be formed on the surface immediately. If the oxide layer is not dirty, the ink will have good adhesion to it. However, in actual production, the aluminum foil paper is contaminated by lubricants and environmental dust, forming a very thin film that affects the adhesion performance of the ink. Therefore, the aluminum foil paper used for printing must be treated with a pre-printing etching coating to eliminate the dirt of lubricants and enhance the adhesion between the ink and the foil surface.
