Paper, labels made therefrom and methods of making paper and labels

摘要

Paper is disclosed for use in making repositionable or removable adhesive labels. Figure 2 illustrates a preferred construction of the paper according to the disclosure. Paper (20) is coated with top coat (21) which in turn is coating with a release layer (22). Top coat (21) may be a single or multiple layers, such as two layers. The top coat is useful on thermal paper to avoid activation of the thermal layer by handling of the paper or by the release layer. On the opposite side of the paper, a primer and/or cleaning layer (or layers) (23) is provided and on that an adhesive layer (24), preferably applied in two or more layers. Adhesive (24) is arranged in a series of discrete areas, particles or spots. These are preferably individually isolated and spaced apart. They are preferably symmetrically arranged on either side of the center line (C). Paper (20) is a light weight paper, preferably having a weight of 40 to 65 gsm. For POS printers the paper is a thermal paper having a thermally responsive treatment on the surface facing the top coat layer (21). Paper can be utilized that has a suitable top coating from the paper mill, or a suitable top coat can be applied in line.
