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 pulling) 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.
Claims16
A label, comprising:
- a substrate having a front side and a back side;
- a thermal-sensitive coating and warning layer coating on the front side of the substrate;
- and
- an adhesive on the back side of the substrate;
- wherein the warning layer coating is adapted to activate and provide a visible indicia on the front side when a directional force is applied to the label;
- wherein the warning layer coating further including two or more food safe liquids, each food safe liquid adapted to exhibit a white color, a clear color, or remain invisible on the label when not activated and to provide the visible indicia when mixed together on activation by the directional force.
A label roll, comprising:
- a substrate;
- and
- a plurality of labels defined within portions of the substrate, each portion of the substrate represents each label, and each portion of the substrate comprises a front side having a thermal-sensitive coating and a warning layer coating, and each portion of the substrate of each label including a back side having an adhesive coating;
- wherein the warning layer coating is adapted to activate when a horizontal or vertical force is applied to each of the plurality of portions of the substrate for each of labels and when activated the warning layer coating releasing a colored material that provides visible indicia on the front side of each portion of the substrate for each of the labels;
- wherein the warning layer coating further including two or more food safe liquids, each food safe liquid adapted to exhibit a white color, a clear color, or remain invisible on the label when not activated and to provide the visible indicia when mixed together on activation by the horizontal or vertical force.
