Abstract
A tamper evident tag is provided having a sealant layer, and ink layer and an oxygen barrier layer. The tag may be a film-based tag incorporating a color shifting ink layer located in the sealant layer and a bar code in the ink layer. The tag may be placed over one or more perforations in the bottom end covering of a container. When the container is opened, air enters the interior of the container, passes through the perforations and into the sealant layer. When air reaches the color shifting ink layer, it changes to a color the same as or similar to the bar code, rendering the bar code illegible.
