Surface anomalies in spray packaging materials and their relationship to corrosion.


The surfaces of spray package materials are far from perfect. The metal-making process, the processes used to fabricate metal containers, coating application processes and the foil lamination formation process often produce surface anomalies that could be mistaken for corrosion, or thought to be the starting-point for corrosion.

Let’s take a look at the more common surface anomalies that are found in various types of spray packages.
