  • Patent number: 6051311
    Abstract: A roll of label continuum includes an elongated label substrate having opposite sides, a pressure-sensitive adhesive layer on one side of the substrate, labels on the opposite side of the substrate and a release layer extending over the labels. The release layer and the pressure-sensitive adhesive layer are disposed on the outer opposite sides of the label continuum such that when the label continuum is rolled up into a roll, the pressure-sensitive adhesive layer is temporarily adhered to the release layer, the pressure-sensitive adhesive layer being released from its temporary adherence to the release layer as the label continuum is unrolled from the roll.

  • Patent number: 5855722
    Abstract: This invention relates to a label continuum comprising a long label substrate, a pressure-sensitive adhesive layer formed by transferring to the back of the label substrate and a release layer formed on the surface of the label substrate, and in the invention the label substrate is rolled up such that the release layer and the pressure-sensitive adhesive layer are false-stuck to each other.
