16. The device of claim 13 , wherein:
the discrete openings comprise elongated slots.
17. The device of claim 13 , wherein:
the handle defines an undersurface, at least a portion of which is coated with an adhesive that adheres the handle to the second side of the polymeric film.
18. The device of claim 13 , wherein:
the handle defines an undersurface that is substantially free of adhesives, and wherein the handle is adhered to the polymeric film by an electrostatic force.
19. The device of claim 18 , wherein:
the handle comprises a layer of conductive material.
20. The device of claim 19 , wherein:
the handle further comprises a layer of non-conductive material.
21. The device of claim 13 , wherein:
the handle includes an inner peripheral edge forming a window through the handle, the handle including a cut extending between and interconnecting the inner and outer edges.
22. The device of claim 21 , wherein:
the handle includes a tab extending into the window immediately adjacent the cut.
23. The device of claim 22 , wherein:
the tab defines a side edge immediately adjacent the cut facing a portion of the inner peripheral edge on an opposite side of the cut relative to the tab, and wherein:
the side edge of the tab and the portion of the inner peripheral edge define an angle therebetween that is substantially less than ninety degrees.
24. The device of claim 21 , wherein:
the inner peripheral edge defines a pair of spaced-apart linear inner edge portions that are parallel to one another, and wherein the outer peripheral edge defines a pair of linear outer edge portions that are parallel to the linear inner edge portions to form a pair of spaced-apart elongated handle portions between the linear inner and outer edge portions.
25. The device of claim 24 , wherein:
the deformations in the handle comprise a plurality of parallel slots through the elongated handle portions.
26. A wound dressing, ingredient delivery device or IV hold-down comprising:
a handle;
a polymeric film having first and second sides, wherein at least a portion of the first side of the polymeric film is coated with an adhesive material;
the handle being electrostatically adhered to the second side of the polymeric film without adhesive material, the handle defining an outer peripheral edge extending around substantially the entire handle, and including an enlarged opening through a central portion of the handle defining an inner edge that is spaced-apart from the outer edge, the handle including a first cut through the handle connecting the outer edge of the handle to the inner edge, and a plurality of second cuts through the handle disposed about the enlarged opening, and wherein the second cuts are not connected to either the outer peripheral edge or to the inner edge; and
