Production process of medicinal aluminum foil

At present, various tablets, pills, capsules, granules and other medicines are packaged in aluminum-plastic blisters. This kind of packaging can not only better protect the quality and performance of medicines, but also has the advantages of fast packaging production speed and low cost. Light weight, small storage space, convenient transportation and use.

As users have higher and higher requirements for the quality and appearance of medicines, the surface printing color registration can reach 6~8 kinds of characters and patterns, and the quality requirements for pharmaceutical foils are getting higher and higher.

Now most of the packaging of medicinal aluminum foil uses 8011 alloy foil, the thickness is 0.02mm, and the state is H18. The process flow is: billet inspection→rolling→coiling→rolling→slitting→inspection, packaging and storage.
The distribution of rolling passes is 0.3mm(H14)→0.145mm→01072mm→0.032mm→2×0.02mm(H18). Among them, the 1st and 2nd passes are rolled on the rough rolling mill (the crown of the rolling wheel is 0.09mm and the Ra value is 0.3um);
The 3rd and 4th passes are rolled on the intermediate rolling (the crown of the rolling wheel is 0.10mm, and the Ra value is 0.15um).
The rolling speed of the 1st, 2nd and 3rd pass is 800mPmin ~ 1200mPmin, and the rolling speed of the 4th pass is 400mPmin ~ 450mPmin.
