5. Choice of protection specifications according to content
Matching the protection to the contents is a key factor in the expected performance of a metal box. The materials and manufacturing techniques described above offer a very wide range of possibilities. In making their decisions, manufacturers also rely on a wealth of experimental data based on tests under real-life conditions.
5.1 Selection criteria
The choice of an optimum protection specification must take into account a variety of criteria, including the following:
-
the corrosiveness of the contents, including
acidity,
the presence of sulfur ;
content sensitivity (color, taste) when interacting with...
