Flaschenhalsband-Etiketten

Gegenwärtig, the thickness of aluminum foil for Etiketten für Flaschenhalsbänder is 0.0115mm, and the mechanical property test generally uses a strip tensile specimen. das ist, a tensile specimen with a width of 15mm, a length of 170mm and a gauge length of 100mm in the parallel part. According to the user’s use effect, The tensile strength of aluminum foil 8011 die, 0.0115 mm for beer bottle collar label is generally between 80 und 90 N / mm2, and the elongation is 2% nach 2.5%. In Ergänzung, different users have additional requirements, such as burst strength. These technical indicators are generally inspected by the wine label printing factory, and the aluminum foil supplier factory does not conduct separate inspections through process assurance.

The thinner beer bottle collar labels aluminum foil can only be used for sealing after color coating, so the requirements for its surface quality are higher, and the surface of the aluminum foil is not allowed to have defects such as oil spots and obvious imprints. Nach dem Bierflaschenhalsetikett gedruckt, small holes should be evenly punched on the surface of the aluminum foil. This is a unique process requirement of the bottle neck label. Deshalb, the requirements for the pinhole degree of the aluminum foil for bottle label are very strict, and pinhole defects on the aluminum foil are hardly allowed to appear.

If there are many original pinholes in the aluminum foil, plus the small holes on the finished beer bottle label itself, the surface of the aluminum foil becomes a “sieve”, and other properties of the aluminum foil will also deteriorate, which will seriously affect the labeling speed of the brewery. jedoch, at present, the Chinese beer Etiketten für Flaschenhalsbänder supplied with cast-rolled billets can achieve smaller pinholes in aluminum foil, which can basically meet the requirements of users in this regard.
