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.
Claims28
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 deposited on top of the second surface of the PSA layer, the detack layer comprising a mixture of at least a tackifier and a plasticizer, the tackifier to the plasticizer weight ratio being in the range 25:75 to 75:25, the detack layer having a melting point above about 50° C., wherein the detack layer has a surface coverage of at least 40% of the second surface of the PSA layer, and the PSA layer to the detack layer weight ratio is in the range of about 2:1 to about 10:1.
A label laminate comprising:
