As we know, both AISI 316 and AISI 304 stainless steel are perfectly suitable for pharmaceutical packaging. In fact, they, not by chance, are both among the most used materials by manufacturers of packaging machines created for this sector.


Pharmaceutical industry: why use stainless in these cases?

Stainless steel is, in fact, is extremely hygienic. This peculiarity (essential for the pharmaceutical industry) depends on several characteristics of this material. We can see below:

  • Excellent corrosion resistance (the material doesn’t yield to the substances with which it comes into contact)
  • Doesn’t need protective coatings (these, in fact, wearing out could give rise to cracks and indentations that generally end up harboring germs and bacteria
  • Compact surface without roughs (which ensures waterproofness to external substances)
  • High bacterial removability
  • Low bacterial reretention.
