A stacked pad of large adhesive tape sheets containing a plurality of superimposed tape sheets formed from a substrate with an area of differential release, which extends less than the full length and width of the substrate. The second major surface of the substrate includes a layer of an adhesive. Sequential tape sheets in the pad are configured and arranged with the area of differential release alternating between first and second corners of the sheets with the adhesive layer of each tape sheet is releasably adhered to an adjacent tape sheet at a higher adhesion level, except for the area of differential release which adheres to an adjacent tape sheet at a lower adhesion level.

Tape sheet pads and dispenser and method of dispensing individual tape sheets from such pads

A dispenser for dispensing a stacked pad of adhesive tape sheets is disclosed. The dispenser comprises a base having transversely spaced first and second major surfaces, first and second longitudinal ends defining a length, and first and second lateral sides defining a width. The dispenser further comprises a pair of laterally opposed side tabs proximate the first longitudinal end of the base which are transversely spaced from the first major surface of the base and laterally extend inward from the sides of the base so as to extend over the first major surface of the base. Substantially the entire first major surface of the base remains exposed.

A method of making embossed optical polymer films and embossed optical polymer films made are described. The embossed optical polymer films have substantially the same optical properties as unembossed optical polymer films. The method includes providing an optical polymer film having first and second major surfaces, softening at least one of the first and second major surfaces to produce a softened surface, embossing the softened surface to produce an embossed optical polymer film, and cooling the embossed optical polymer film.
