Linerless labels are constructed in such a way that when they are manually dispensed they do not tear, but rather rip (separate cleanly) along predefined perforation lines. This is accomplished by providing those cuts of the perforation lines that intersect the slits or side edges of a composite web of linerless labels (and thus the side edges of individual labels when dispensed) have a length great enough to facilitate the start or end of ripping action. The length of each of these end-edge/slit intersecting cuts is at least twice (preferably at least four times) as great as the normal cuts of the alternating cuts and ties forming a perforation line, typically having a length of between about 0.125-0.25 inches (and spaced from each other between about 0.5-1.0 inches), when each of the standard cuts has a length of about 0.012-0.018 inches.
