Aluminium Blisterfolie Fabrik Prozesstechnologie

Aluminium blister foil factory in China manufacturing high quality 8011 und 8021 Aluminiumfolie für pharmazeutische Blisterverpackungen mit fortschrittlicher Prozesstechnologie. Die medizinische Aluminiumfolie besteht aus einem elektrolytischen Aluminiumblock, der einem Kalandrierungsprozess unterzogen wird. Es beinhaltet normalerweise Gusswalzen (Warmwalzen) – Kaltwalzen – Zwischenglühen – Grobwalzen – doppeltes Rollen – spalten und schneiden – finished surface heat treatment – inspection – packaging and other processes.

Because the production process uses smelting, casting and calendering production, due to many factors such as metallurgical quality, roll surface quality, physical and chemical properties of rolling oil, process operation technology and production site environment, various quality defects are inevitable in Aluminium Blisterfolie:

1, Lochkamera
It is one of the most important defects. The size and number of pinholes of medicinal aluminum blister foil have a decisive influence on the moisture resistance, gas barrier and opacity of pharmaceutical packaging. Since pinholes in aluminum foil are penetrating defects, health foods and medicines are invaded by oxygen, Wasserdampf und Licht, which may reduce or deteriorate the efficacy. Deshalb, the aluminium blister foil factory requirements for pinholes are very strict.

2, Thermal stability:
In the process of use, if the mechanical properties of the blister aluminium foil are low, the foil breakage and cracking often occur in the production, thereby affecting the continuous printing and coating. If the aluminum foil is broken in the drying tunnel of the printing machine, the temperature of the drying tunnel is high, and it is generally necessary to cool down before it can be connected, thereby affecting the production progress. So the professional Aluminium Blisterfolie Fabrik attaches great importance to the thermal stability of medicine foil.
