1. 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.
