Abstract
According to an embodiment of the present disclosure, a method of labeling a plurality of products includes coating a pressure sensitive adhesive to a roll of face stock, the roll of face stock configured to be converted to a plurality of individual labels aligned in a single lane; singulating an individual label from the roll of face stock; and applying the individual label to a product of the plurality of products, wherein the coating, singulating and applying are conducted sequentially in a single continuous operation with a single continuous web of material.
Claims20
A label laminate comprising:
- a filmic or a paper substrate, said substrate having a first surface and a second surface;
- a pressure sensitive adhesive (PSA) layer, said PSA layer being tacky and having a first surface and a second surface, the first surface of the PSA being in contact with the second surface of the substrate;
- and
- a detack layer on top of the second surface of the PSA layer, said detack layer comprising a mixture of at least a solid tackifier and a solid plasticizer, the tackifier to the plasticizer weight ratio being in the range 25:75 to 75:25, and having a melting point above about 50° C., wherein the detack layer has a surface coverage of less than 100% of the second surface of the PSA layer;
- wherein the PSA layer to the detack layer weight ratio is in the range of about 1:2 to about 10:1 and the surface coverage is obtained by spraying, printing, sprinkling, sieving, electrostatic deposition, dusting or powder coating the detack layer on top of the second surface of the PSA.

A label laminate comprising:
- a filmic or a paper substrate, said substrate having a first surface and a second surface;
- a pressure sensitive adhesive (PSA) layer, said PSA layer being tacky and having a first surface and a second surface, the first surface of the PSA being in contact with the second surface of the substrate;
- and
- a detack layer on top of the second surface of the PSA layer, said detack layer comprising a mixture of at least a solid tackifier and a solid plasticizer, the tackifier to the plasticizer weight ratio being in the range 25:75 to 75:25, and having a melting point above about 50° C., wherein the detack layer has a surface coverage of less than 100% of the second surface of the PSA layer;
- wherein the substrate comprises at least a perforated line or a weakened line configured to convert the label laminate to a plurality of individual labels and the detack layer is tackifiable in less than 3 seconds upon exposure to a thermal or an infra-red radiation source and upon tackifying, the detack layer begins blending with the PSA layer to form a PSA blend, the detack layer and the PSA blend being tacky, and the detack layer and the PSA blend staying tacky for a period of at least 30 minutes.

- a pressure sensitive adhesive (PSA) layer, said PSA layer being tacky and having a first surface and a second surface, the first surface of the PSA being in contact with the second surface of the substrate;
- and
- a detack layer on top of the second surface of the PSA layer, said detack layer comprising a mixture of at least a solid tackifier and a solid plasticizer, the tackifier to the plasticizer weight ratio being in the range 25:75 to 75:25, and having a melting point above about 50° C., wherein the detack layer has a surface coverage of less than 100% of the second surface of the PSA layer;
- wherein the filmic substrate is a plastic film and the label laminate remains clear after exposure to heat to tackify the detack layer, thereby forming a clear label providing a no-label look to a product to which the clear label is applied and the label laminate is printed to form labels, said labels are cut, activated and applied to containers.
