1. A tab for sealing unbound edges of a mailpiece, said tab comprising:
- a flexible film having a periphery region surrounding a substantially continuous inner region, wherein said flexible film is a substantially transparent polymer-based film and wherein said periphery region extends along an entire periphery of said flexible film to less than, or equal to, 10% of the longest cross-sectional dimension of the flexible film;
at least one adhesive layer disposed about at least a portion of a bottom surface of said flexible film;
a first set of a plurality of adjacent parallel peripheral flaws disposed within said periphery region of a first side of said flexible film; and
a second set of a plurality of adjacent parallel peripheral flaws disposed within said periphery region of a second side of said flexible film, said second side generally opposing said first side; and
wherein said peripheral flaws of said first and said second set are configured to introduce a weakness into said flexible film to facilitate tearing said tab into two pieces and are disposed only in said first and said second sides, respectively.

Abstract
A tab for sealing an unenveloped mailpiece having a front surface, a rear surface, and at least one unbounded edge separating the front and rear surfaces. The tab includes a flexible film configured to extend from the front surface across the unbounded edge to the rear surface. The flexible film has a periphery region and a substantially continuous inner region. At least one adhesive layer is disposed about at least a portion of a bottom surface of the flexible film configured to adhere to the front and the rear surfaces of the mailpiece. At least one peripheral flaw is disposed within the periphery region and generally aligned with unbounded edge.

4. A system comprising:
a tab for sealing an unbound edge of a mailpiece, said tab comprising; a flexible film comprising a substantially transparent polymer substrate having a first and a second generally opposing side; at least one adhesive layer disposed about at least a portion of a bottom surface of said flexible film; a first set of a plurality of adjacent parallel peripheral flaws disposed within said first side of a periphery region of said flexible film, said plurality of adjacent parallel peripheral flaws of said first set each extending along a plurality of axes; and a second set of a plurality of adjacent parallel peripheral flaws disposed within said second side of the periphery region of said flexible film, said plurality of adjacent parallel peripheral flaws of said second set each extending along a plurality of axes generally aligned with said plurality of axes of said plurality of peripheral flaws of said first set; wherein said plurality of adjacent parallel flaws are configured to introduce a weakness into said flexible film extending between said first and said second sides to facilitate tearing said tab into two pieces; wherein all peripheral flaws in said periphery region extend continuously from said periphery and are disposed only in said first and said second sides, respectively; wherein said periphery region extends along an entire periphery of said flexible film to less than, or equal to, 10% of the longest cross-sectional dimension of the flexible film and surrounds a substantially continuous inner region of said flexible film; and wherein said substantially continuous inner region of said flexible film is not perforated. - View Dependent Claims (5, 6)

10. A system comprising:
-
an unenveloped mailpiece comprising a front surface, a rear surface, and an unbounded edge separating said front and rear surfaces; and a tab comprising; a flexible film having a periphery region surrounding a substantially continuous inner region, wherein said flexible film is a substantially transparent polymer-based film and wherein said periphery region extends along an entire periphery of said flexible film to less than, or equal to, 10% of the longest cross-sectional dimension of the flexible film, wherein said tab comprises a first and a second secured region configured to be adhered to said front and said rear surface of said unenveloped mailpiece, respectively, and a folded region extending across said unbounded edge and between said first and said second secured region; at least one adhesive layer disposed about at least a portion of a bottom surface of said first and said second secured region of said flexible film; a first set of a plurality of adjacent parallel peripheral flaws disposed within said periphery region of a first side of said folded region; and a second set of a plurality of adjacent parallel peripheral flaws disposed within said periphery region of a second side folded region, said second side generally opposing said first side; wherein said peripheral flaws of said first and said second are configured to introduce a weakness into said flexible film to facilitate tearing said tab into two pieces within said folded region; and wherein said first set and said second set of a plurality of adjacent peripheral flaws are separated by a first and a second portion of said periphery region and are disposed only in said first and said second sides, respectively. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
