Zusammenfassung:The present invention provides a method of improving the peel-plate dispensability of die-cut and matrix-stripped label constructions which do not generally have the required minimum stiffness to be successfully peel-plate dispensed, particularly at room temperature. More particularly, the invention relates to a method of improving the peel-plate dispensability of a die-cut and matrix-stripped polymer film label construction comprising a facestock, a release liner, and a substrate adhesive layer between the facestock and the liner, which method comprises maintaining the temperature of at least the leading edge of the label below about 20° C. as the leading edge of the label construction moves over a peel-plate and the label is separated from the release liner. Maintaining the temperature of the label, of at least the leading edge of the label at a reduced temperature such as from about -15 to about +15° or even 20° C. temporarily increases the stiffness of the label, and, thus, when the cooled label is passed over the peel-plate, the label has the required stiffness to cause it to separate from the release liner and proceed in a straight line toward the application substrate. The invention is particularly applicable to thin label constructions (e.g., faceless constructions) which do not have the requisite stiffness at room temperature to be peel-plate dispensable at room temperature. The facestocks of the label constructions may be monolayer facestocks or multilayer facestocks.
