En el presente, the thickness of aluminum foil for etiquetas de cuello de botella is 0.0115mm, y la prueba de propiedades mecánicas generalmente utiliza una muestra de tracción en tira. es decir, una muestra de tracción con un ancho de 15 mm, una longitud de 170 mm y una longitud de calibre de 100 mm en la parte paralela. Según el efecto de uso del usuario., La resistencia a la tracción del papel de aluminio. 8011 la, 0.0115 mm for beer bottle collar label is generally between 80 y 90 N / mm2, and the elongation is 2% a 2.5%. Adicionalmente, 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. Después de la etiqueta del cuello de la botella de cerveza está impreso, small holes should be evenly punched on the surface of the aluminum foil. This is a unique process requirement of the bottle neck label. Por lo tanto, 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. sin embargo, at present, the Chinese beer etiquetas de cuello de botella supplied with cast-rolled billets can achieve smaller pinholes in aluminum foil, which can basically meet the requirements of users in this regard.
