Abstract
A xerographically printable label comprises a layer of sheet material, e.g. paper or polyvinyl chloride film, having a printable upper surface and an adhesive-coated lower surface, and a release liner removably adhering to the lower surface of the layer of sheet material. The release liner comprises a first layer of paper having a release coating on its upper surface and a water-impermeable adhesive on its lower surface, and a layer of textured paper bonded to the first layer by the water-impermeable adhesive. The first paper layer is thus protected from substantial moisture gain or loss, on one side by the release liner, and the other side by the water-impermeable adhesive.
Claims18
A release liner comprising a layer of untextured paper having on one side thereof a moisture-resistant release coating and on the other side thereof a moisture-impermeable adhesive and a layer of embossed paper adhered to the other side of said adhesive coating.
A label comprising (a) a layer of sheet material having a printable upper surface and a moisture-impermeable adhesive-coated lower surface, and (b) a release liner comprising a first layer of paper having a release coating on one surface thereof and a moisture-impermeable adhesive on the other surface thereof and a second layer of paper which is embossed and bonded to said first layer of paper by means of said moisture-impermeable adhesive on said other surface of said first layer of paper.
A xerographically printable label comprising (a) a sheet of polymeric film having a printable upper surface and a moisture-impermeable pressure-sensitive adhesive coated on its lower surface, and (b) a release liner comprising a sheet of non-embossed paper having a release agent coated onto one surface thereof and a moisture-impermeable adhesive coating on the other surface thereof, and a sheet of embossed paper which is bonded to said layer of non-embossed paper by means of said moisture-impermeable adhesive coating on said other surface of the non-embossed paper sheet.
