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.

A method of making linerless labels using a coating machine, and a substrate having first and second faces, comprising the steps of: (a) continuously moving the substrate in a first direction through the coating machine; (b) with the coating machine, applying in a predetermined sequence to the moving substrate a tie coating coat consistently essentially of about 30-40 parts silica dispersion, about 20-35 parts polyvinyl alcohol, and about 30-40 parts water to the substrate first face, and further applying a release coating to the substrate second face, and a pressure sensitive adhesive to the tie coating; (c) cutting the substrate to form individual labels; and (d) rolling the substrate into a roll, with the release coated second face facing to an outside of the roll.
