  • Patent number: 6547887
    Abstract: Multilayer PSA label constructions that achieve a good balance of properties, namely, adhesive performance, convertibility, and laser printer performance, and, optionally, good wet-out on plastic substrates and low haze. The multilayer PSA construction comprising a facestock, a multilayer adhesive coating, and a release liner. The adhesive coating is made of a face side adhesive (FSA) layer comprising a first emulsion acrylic PSA, which is in contact with the inner surface of the facestock, and a liner side adhesive (LSA) layer, comprising a second emulsion acrylic PSA different from the first acrylic PSA, which is in contact with the FSA. The adhesive coating has a coat weight of less than about 26 g/m2 and a flow of less than about 50 &mgr;m at room temperature. The construction exhibits a loop tack value of at least about 3.5 N/25 mm at 5° C. on a polyethylene substrate.

  • Patent number: 6503620
    Abstract: The present invention relates to improved performance multilayer PSA constructions useful for making labels. In one embodiment the invention relates to a multilayer PSA construction comprising: (A) a multilayer adhesive laminate having an overall thickness of less than about 100 microns and comprising (I) at least one composite PSA layer comprising a continuous phase of a pressure sensitive adhesive and a discontinuous phase of non-adhesive filler particles, filler particle aggregate, or a mixture thereof, and (ii) at least one second PSA layer which is in contact with the composite layer and contains no filler or less filler than the composite layer, and (B) a facestock which is in contact with and adhered to either the composite layer or the second PSA layer of the multilayer adhesive laminate.

  • Patent number: 5958512
    Abstract: An apparatus for forming bands of reduced coat weight of a coating on a coated web that is moving through a laminating machine includes a supply of fluid and a nozzle for directing a stream of fluid from the supply toward the web, said nozzle having a relatively small outlet aperture for directing a relatively narrow width stream of fluid toward the web compared to the width of the web to impinge on the web to reduce the coat weight over a relatively narrow width band. The bands may be formed in the machine direction of travel of the web, across the width of the web in a direction other than the machine direction and may be of various width and may be precisely or randomly placed. The reduced coat weight areas may be narrow bands or broader areas of the web.
