Photo anodized aluminum bar codes are known for maintaining their readability in a wide range of environments and uses. They perform better than other types of labels in demanding environments with the exception of those environments that chemically attack aluminum, such as highly caustic or highly acidic applications. Recommended performance is in a pH range of 5.5 to 8.5.

      The Foil InfoDot is produced using an image intensification process on the photo anodized aluminum which results in higher product performance in heat ant ultraviolet conditions.
