Production For Aluminum Foil For Pharmaceutical

- Nov 14, 2019-

There are two common types of aluminum foil for pharmaceutical on the market, 8011 aluminum foil and 8021 aluminum foil,8011 alloy thickness is generally below 0.05mm, 8021 alloy thickness is more than 0.05mm. The main production process of aluminum foil for pharmaceutical is: blank inspection - open blank rolling - open partial rolling - combined steckel mill - rolling finished product - cutting - furnace annealing - finished packaging. 

Aluminum foil for pharmaceutical  surface requirements without oil, no bright crystal, no black line, no pinhole, no macular, no lotus leaf side, etc. In the production process, for the surface and performance of the control, mainly with a few points:

7

1.  First of all from the source to control the quality, strict inspection billet;

2.  And then in the rolling process, through the roller cleaning and roughness control, rolling oil selection, reduce the viscosity of rolling oil and control the speed of operation of the machine and other aspects to control the surface quality;

3.In the cutting process, to ensure that the edge of the aluminum part of the edge of the neat, can not appear lotus leaf side and other quality problems;

4.Finally, in the annealing process, according to the performance requirements of the foil to control the annealing time and annealing temperature, to ensure that clean up the oil.
With the development of the pharmaceutical industry, aluminum foil for pharmaceutical with its excellent moisture resistance, barrier, chemical resistance, chemical stability, health, the proportion of rising applications, appearance and quality requirements are getting higher and higher, the market prospects are very broad.
