    摘要： Prelaminate pressure-sensitive adhesive (PSA) constructions comprise, a first substrate, a coating or release material on a surface of the first substrate, a PSA layer disposed on the coating of release material, and a detackified layer (DL) disposed on a surface of the PSA layer to form a continuous film covering the PSA layer. In first and second embodiments of the construction the DL is activatable to form a tacky layer on top of the PSA layer for lamination with a second substrate. In a third embodiment, the DL includes constituents that when activated migrate into the PSA layer to expose the PSA layer tacky surface for lamination with a second substrate. The prelaminate PSA constructions are completely nonblocking to a minimum 24 hour blocking temperature of about 50° C. at pressure of about 40 kilopascals, thereby allowing such prelaminate PSA construction to be collected, stored, and or transported before being laminated without adhesive interference occurring between continuous layers. The DL in each embodiment is activatable in less than five seconds to provide a tacky layer having a sufficient open tack time to permit lamination at less than about 100° C.

    摘要： Overlaminated faceless PSA label constructions of this invention comprise a low material cost, thin prelaminate PSA construction having a layer of pressure-sensitive material disposed on a release surface of a removable substrate, and a nonblocking continuous film disposed over a surface of the layer of pressure-sensitive adhesive to render the pressure-sensitive adhesive tack free. An optically transparent overlaminate film layer is disposed over the nonblocking continuous film, and a printed indicia is interposed between the overlaminate film layer and nonblocking continuous film. The prelaminate PSA construction does not include a conventional facestock formed from paper, cardboard or plastic, and is highly conformable. The overlaminated film layer can be applied to the prelaminate faceless PSA construction by pressure lamination, via a further PSA layer interposed between continuous film and the overlaminate film layer, or by heat and pressure by forming one of the continuous film or overlaminate film layers from a heat-activatable material that itself forms a laminating adhesive surface. Alternatively, the overlaminate film layer can be applied to the prelaminate PSA construction as a film-forming material. The overlaminated PSA construction has a sufficient Gurley stiffness to permit high-speed converting and dispensing by peel plate equipment without sacrificing the high degree of conformity provided by the underlying prelaminate PSA construction.
