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.
Claims21
(canceled)
A method, comprising:
- applying, by a press, a warning layer coating on top of a thermal-sensitive coating coated a front side of a substrate, wherein the substrate defines a roll of labels, wherein the warning layer coating is adapted to disperse colored material or reveal a printed warning indicia on the front side of each label responsive to a directional force applied to that label;
- and
- applying, by the press, an adhesive to a backside of the substrate.
A method, comprising:
- providing a substrate with a front side and a back side;
- applying a warning layer coating on a front side of the substrate atop a thermal-sensitive coating, the warning layer coating comprising heat-resistant capsules, each capsule containing a food safe liquid that exhibits no color until activated;
- and
- applying an adhesive on a back side of the substrate;
- wherein the warning layer coating is adapted to provide a visible indicia on the front side when a directional force ruptures the capsules.
A method, comprising:
- providing a substrate coated with a thermal-sensitive coating on a front side of the substrate;
- applying a warning layer coating atop the thermal-sensitive coating, wherein the warning layer coating is adapted to withstand heat and not activate when the thermal-sensitive coating is imaged by a thermal printer, and wherein the warning layer coating includes microencapsulated food safe inks that rupture and provide visible indicia on the front side of the substrate when a directional force is applied to the substrate;
- applying a release coating atop the warning layer coating;
- applying an adhesive coating to a back side of the substrate;
- and
- winding the substrate into a roll of linerless labels.
