Adding aluminum foil to the neck of the beer bottle can reduce the transmission of ultraviolet light and reduce the generation of "sunshine odor". Preventing and reducing corrosion is also one of its functions.
Of course, beauty and refinement are also very important, or the most important purpose. It makes people think that beer is of high grade. Some brands of beer bottles use aluminum foil labels and have anti-counterfeiting functions.
Chalco Beer Label Aluminum Foil has smaller and less pinholes in aluminum foil, which can meet the different printing needs of customers.
Chalco Aluminum Foil for Beer Mark has high surface quality, and the printed wine labels are more beautiful and delicate.
Chalco Aluminum Foil for Beer Mark has good mechanical properties, which can meet the additional performance requirements of customers.
Chalco Aluminum Foil for Beer Marks can better prevent UV light transmission, prevent and reduce corrosion.

The thinner beer label aluminum foil can only be used for sealing after color coating, so the requirements for its surface quality are higher. The surface of the aluminum foil is not allowed to have defects such as oil spots and obvious marks.
The top and neck labels of beer bottles and other bottles should be evenly punched with small holes on the surface of the aluminum foil after printing. This is a unique process requirement for beer labels. Therefore, the requirements for pinhole size of aluminum foil are very strict, and pinhole defects are almost not allowed on aluminum foil.
If there are many pinholes in the original aluminum foil, plus the small holes on the finished beer label itself, the surface of the aluminum foil will become a "sieve", and other properties of the aluminum foil will also deteriorate, which will seriously affect the labeling speed of the brewery.
However, Chalco aluminum foil for beer bottles can achieve smaller and fewer aluminum foil pinholes, which can well meet the needs of users in this respect.
At present, the thickness of the aluminum foil used for beer labels is 0.0115mm, and the mechanical performance test generally uses a strip tensile sample, that is, a tensile sample with a parallel part width of 15mm, a length of 170mm, and a gauge length of 100mm.
According to the user's use effect, the tensile strength of 8011 O temper, 0.0115mm beer label aluminum foil is generally between 80-90N/mm2, and the elongation is 2%-2.5%.
In addition, different users have additional requirements, such as burst strength and so on. These technical indicators are generally inspected by the wine label printing factory, and the aluminum foil supply factory passes the process guarantee instead of testing separately.
The mechanical properties of Chalco aluminum foil for beer bottle neck label are as follows:
Tensile strength: ≥80 Mpa
Surface wetting tension: Class A
Whether it is made of hot-rolled billet or cast-rolled billet, the chemical composition of the aluminum foil for beer label is 8011 alloy.
The control range of its chemical composition is mainly to consider the technical indicators such as tensile strength, elongation and pinhole of aluminum foil to meet the requirements of users.
The main components of the alloy are as follows:
|Chemical composition of 8011 aluminum foil|
The production process of Chalco aluminum foil for beer bottles is as follows:
Hot rolling/cast rolling smelting→composition adjustment→stationary furnace refining→online degassing→adding grain refiner→filtering→cast rolling→cold rolling→heat treatment in middle thickness→aluminum foil rolling→double rolling→finished product slitting→Finished product heat treatment→ check the package
FOB price of aluminum foil on beer bottles = SMM A00 aluminum ingot price on the day of inquiry + processing fee / exchange rate
Aluminum ingot price is SMM A00 aluminum ingot price.
FOB price can be US dollar price, Euro price, or Renminbi price, according to customer requirements.
The beer label is developing towards the trend of thinning, alloying and high performance, and the goal of the process research of aluminum foil manufacturers is also generally in this direction.
Thinning trend of aluminum foil for beer labels. At present, the general thickness of aluminum foil for beer labels is 0.0115mm, and some enterprises have proposed to reduce its thickness to 0.0112, 0.0105, 0.01mm, and the requirements for material properties will not change.
At present, our company has produced aluminum foil for beer labels with a thickness of less than 0.0112mm by adjusting the 8011 alloy composition and annealing process system.
Our company has also conducted research on the alloying of aluminum foil for beer labels. The 8000 alloy O-temper aluminum foil for beer labels developed at present has a thickness reduced to 0.0105mm, and its strength can reach 85-95N/mm2, and its elongation can reach 85-95N/mm2. Extensibility (gauge length 100mm) can reach 2.5% to 3.0%. More than 95% of the products have no pinholes, and the product quality has been recognized by many foreign users.
