    摘要： An adhesive tape, label, or the like comprises a barrier layer of substantially liquid-impervious material, a layer of normally tacky pressure-sensitive adhesive layer being adherent to one surface of the barrier layer and the liquid solvent-activatable adhesive layer being adherent to the other surface of the barrier layer, and a cover layer bonded to the pressure sensitive adhesive layer, the barrier layer being substantially impervious to solvent liquids which render the solvent-activatable adhesive layer adhesively tacky, and the cover layer being such as to remain bonded to the pressure sensitive adhesive layer when the solvent-activated adhesive layer is adhered to an object, thereby permitting the cover layer to carry a label legend. The barrier layer may comprise a thin sheet of thermoplastic film forming material e.g. polyesters such as the condensation copolymer of ethylene glycol and terephthalic acid; polyolefins such as polyethylene, polypropylene and olefin copolymers; polycarbonate; polyvinyl fluoride; fluoro carbon polymers such as the copolymer of tetrafluoro ethylene and hexafluoropropylene. The tape, label or the like may be in the form of a web wound upon itself in roll form, which may include a release-coated linear e.g. release coated glassine paper, interleaven between adjacent spiral rows of the web. The cover layer which may be a thin layer of thermoplastic film-forming material e.g. condensation copolymer of ethylene glycol and terephthalic acid, may be bonded to the layer of pressure-sensitive adhesive. The cover layer may include a decorated surface in contact with the layer of pressure sensitive adhesive e.g. decorated with printed areas and metallized portions. The pressure sensitive adhesive may comprise natural, synthetic, or latex crepe rubber, and rubbery synthetic polymers and copolymers; rosin esters e.g. ester gum, wood rosin, hydrogenated rosin ester, phenol-aldehyde and terpene resins. The solvent-activated adhesive may comprise natural crepe rubber and a terpene phenolic resin. The cover layer may be applied as a decorated preformed film.

    摘要： A dispenser package for adhesive tape transported on a carrier web which includes a cover element and a backing member. A roll of tape is enclosed between the two package elements, and a portion of the cover element is utilized in a functional manner to apply pressure against the tape in order to facilitate release of the tape from the carrier web for dispensing of the tape from the package.
