Алюминиевая технология блистер процесс завода фольги

Aluminium blister foil factory in China manufacturing high quality 8011 а также 8021 алюминиевая фольга для фармацевтической блистерной упаковки с использованием передовых технологий. Лекарственная алюминиевая фольга изготовлена ​​из электролитического алюминиевого слитка, подвергнутого процессу каландрирования. Обычно включает в себя литье прокатки (горячая прокатка) – холодная прокатка – промежуточный отжиг – грубая прокатка – двойная прокатка – расщепление и разрезание – 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 алюминиевая фольга блистера:

1, булавочное отверстие
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, водяной пар и свет, which may reduce or deteriorate the efficacy. Следовательно, 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 завод алюминиевой фольги attaches great importance to the thermal stability of medicine foil.
