Definitions

  • This invention relates to linerless labels, and to methods of making linerless labels.
  • a longitudinally extending label web was perforated at longitudinally spaced transverse lines to provide lines of perforations.
  • the underside of the label web was printed with registration marks.
  • the underside was thereafter coated with pressure sensitive adhesive.
  • a release coating such as silicone was applied to the face side of the label web.
  • the holes formed by the perforations would open up and the adhesive would migrate from the underside through the holes and would adhere to the cut edges at the perforations.
  • the label web was slit into narrow label webs which were then wound into rolls. When the label web was subsequently unwound from the roll, the adhesive that migrated into the holes caused the web to unwind unevenly, in a jerky manner, which affected print quality when the web was printed.
  • a longitudinally extending web of label material having a face side and an underside.
  • a release coating on the face side of the web preferably coats the entire face side including the fibers at the cut edges.
  • the adhesive on the underside of one convolution adheres releasably to the release coating on the underlying convolution. Because the cut edges of the web were coated with the release coating and the adhesive was applied to the web after the perforations were made, release of the web from the roll is enhanced.
  • a roll R of a wound-up web W of linerless labels L there is shown a roll R of a wound-up web W of linerless labels L.
  • the web W has wraps or convolutions 9, one upon the other.
  • the web W extends longitudinally as shown in FIGURES 3 and 4 for example and has a face side 10 and an underside 11.
  • the perforations 12 are preferably made by spaced knife cuts 13 separated by uncut portions or lands 14.
  • a label L can be manually torn from the remainder of the web W.
  • the adhesive 15 is preferably in a uniform coating, however, the coating 11 can alternatively be of the patterned type.
  • a release coating C typically a silicone coating, on the face side 10 of the web W.
  • registration marks 16 printed directly on the underside of the web W. The marks 16 are disposed between the web W and the adhesive 15.
  • the adhesive 15 is preferably transparent or at least translucent.
  • FIGURE 2 there is shown diagrammatically a method by which the linerless web roll R of the invention is made.
  • a wide web W' of label material is fed between a printing roll 17 and a back-up roll 18.
  • the printing roll 17 prints the registration marks 16 on the underside 11 of the web W' in a longitudinal and transverse pattern.
  • the web W' passes between a perforating roll 19 and a back-up roll 20.
  • the roll 19 makes the transverse lines of weakening, specifically perforations, across the web W'.
  • From there the web W' passes between a release coating roll 21 and a back-up roll 22.
  • the release coating roll 21 applies the release coating C to the face side 10 of the web W'.
  • the web W' passes between an adhesive coating roll 23 and a back-up roll 24.
  • the adhesive 15 is thus applied to the underside 11 of the web W', however, if desired the adhesive 15 can be applied over the release coating C.
  • the web W' is slit into narrow label webs W as the web W' passes between a slitting roll 25 and a back-up roll 26. From there the narrow webs W are wound into the rolls R.
  • the perforating roll 19 makes spaced apart cuts 13 in the web W'.
  • the depths and widths of the cuts can vary substantially.
  • some of the cuts 13 may be completely through the web W to provide openings 10'.
  • Other cuts 13 may terminate short of the underside 11 and provide to a heavy score, and even in this event the cuts 13 may open up to provide openings 10' later in the production process due to web tension. In all such cases, there are exposed uncoated fibers at the cut edges.
  • the release coating C covers the cut edges 27 and 28. Adhesive "cold flow" can occur when the web W has been wound into roll R.
