Abstract
An adhesive assembly includes a film having a top and bottom surface. An activatable adhesive is disposed on the bottom surface of the film. A release liner is applied to a surface of the adhesive, opposite the film. The release liner and the activatable adhesive being configured to electrostatically charge the activatable adhesive upon removal of the release liner from the adhesive.
Claims25
An adhesive assembly comprising a face stock having a top and bottom surface, said bottom surface of said film further comprising a preapplied activatable adhesive with a removable release liner, the release liner and the activatable adhesive being configured to electrostatically charge the activatable adhesive upon removal of the release liner from the adhesive.
A rolled adhesive tape, comprising:
- a film having a top and bottom surface, the top surface having an embossed pattern;
- an activatable adhesive applied to the bottom surface of the film;
- wherein, when the tape is rolled upon itself, the embossed pattern from the top surface is transferred to the adhesive;
- and
- wherein, when the tape is unrolled, the activatable adhesive is electrostatically charged by contact electrification with the top surface of the film.
