Abstract
Linerless label stock is produced from a single substrate utilizing a coating machine by moving the substrate through the coating machine and applying a tie coating to the substrate first face, a release coating to the substrate second face, and a pressure sensitive adhesive to the tie coating. The tie coating comprises a dispersion of a pigment, such as silica, with a binder, such as polyvinyl alcohol. The substrate is cut to form individual labels, and is rolled up into a roll with the release coated second face on the outside of the roll. Printing may be applied to the substrate prior to coating, or to the release coating.
