Abstract
A tamper resistant label having two layers. The first layer is a patterned layer in direct or indirect contact with an adhesive layer and the second layer is a protective film with visible indicia applied over the patterned layer. A portion of the protective layer with visible indicia has no adhesion to the patterned layer which allows the protective film to readily separate from and destruct portions of the patterned layer when the film is removed.
