    摘要: 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. It has been discovered that multilayer PSA label constructions exhibiting these properties also exhibit good convertibility and laser printer performance.

    摘要: An improved applicator die for alternately depositing different liquid coating materials on a moving web comprises a die body having switch bars for opening and closing respective flow passageways for supplying the different liquid coating materials to an elongated coating orifice from respective manifolds. The switch bars, flow passageways and manifolds are substantially as wide as and substantially parallel to the coating orifice of the die whereby changeover between different coating materials can be made very rapidly.

    摘要: A method of designing and the resulting thermally stable heated coating die apparatus, the die apparatus including a die having a die geometry and a heating system with heaters and temperature sensors. The method and resultant apparatus provides minimized temperature gradients, flat die lip faces in a die to roll plane and a flat die in a plane perpendicular to die flat lip faces and parallel to substrate width. The method optimizes simultaneously: die geometry, placement of the heaters, placement of temperature sensors, and shielding from operating conditions, using heat transfer and structural numerical modeling and statistical analysis while considering die functionality characteristics, minimum increment of temperature measurement and control accuracy related to minimum acceptable deviation from flatness, coating die material of construction relative to thermo-structural material properties, and desirable coating die material properties.
