Abstract
A label is provided with a warning layer coating integrated or applied to a front side of the label. The warning layer coating is not activated by application of heat; rather, the warning layer coating activates upon a directional force (vertical or horizontal puffing) applied to the label after the label was initially adhered to a container, bag, box, and/or object. Upon activation, visible color or a printed warning indicia is visible on a front surface of the label, providing evidence that the label was removed after initial application or providing evidence that the label was attempted to be removed after initial application.
