Abstract

A W-stacked pads of tape strips dispensable at a low peel angle, comprising a plurality of superimposed tape strips longitudinally reversed so as to align the first end of each tape strip with the second end of an immediately overlaying and an immediately underlying tape strip. The individual tape strips having first and second longitudinal end portions with differential release characteristics, with the second end portion of each tape strip adhered to the first end portion of an adjacent tape strip at an adhesion level having an adhesive strength sufficient to allow release of the second end portion of an intermediate tape strip relative to the first end portion of an immediately underlying tape strip when an immediately overlying tape strip is dispensed from the pad at a low peel angle, while preventing any appreciable longitudinal movement of the second end portion of an intermediate tape strip relative to the first end portion of an immediately underlying tape strip when an immediately overlying tape strip is dispensed from the pad at a high peel angle.
