A hang tab assembly includes a paper outer layer and inner layer. The outer layer may include a hanging panel, a tear-away panel adjacent to the hanging panel, a first kiss-cut path on an upper surface of the outer layer, and a second kiss-cut path on a lower surface of the tear-away panel, the second kiss-cut path offset from the first. The assembly may include a first adhesive disposed on the lower surface of the tear-away panel, and a second adhesive disposed on a lower surface of the inner layer facing away from the outer layer. The outer layer may include a tear-away portion that tears transversely between offset kiss-cut paths to unseal a sealed package and expose internal paper material to provide visual indication that the package has been unsealed.

What is claimed is: 1. A hang tab assembly for sealing and hanging a package, the assembly comprising: a paper outer layer comprising: a hanging panel including a first opening; a tear-away panel adjacent to the hanging panel; a first kiss-cut path extending in a longitudinal direction along a boundary between the hanging panel and the tear-away panel on an upper surface of the outer layer; and a second kiss-cut path extending in the longitudinal direction on a lower surface of the tear-away panel, wherein the second kiss-cut path is offset from the first kiss-cut path in a transverse direction orthogonal to the longitudinal direction; a paper inner layer having a second opening corresponding to the first opening, the inner layer coupled to the outer layer; a first adhesive disposed on the lower surface of the tear-away panel entirely to one side of the second-kiss-cut path; and a second adhesive disposed on a lower surface of the inner layer facing away from the upper surface of the outer layer. 2. A hang-tab package-sealing system, the system comprising: the hang tab sealing assembly of claim 1 ; a package movable between an open and a closed configuration, the package comprising a tuck flap and a side wall, wherein the tuck flap and the side wall are parallel to each other when the package is in the closed configuration, wherein the inner layer is affixed to the tuck flap and disposed between the tuck flap and the package side wall when the package is in the closed configuration, and wherein the package is sealed in the closed configuration by the first adhesive adhering a portion of the tear-away panel to an outer surface of the package side wall and the second adhesive adhering a portion of the inner layer to the tuck flap. 3. The system of claim 2 , wherein the tear-away panel is configured to be partially torn away to unseal the package, wherein when the tear-away panel is torn away, the tear-away panel is configured to separate into: a tear-away portion that separates from the package side wall, the tear-away portion comprising: a full-thickness portion disposed between the second kiss-cut path and a third kiss-cut path spaced apart from the second kiss-cut path and extending in the longitudinal direction on the lower surface of the tear-away panel; and a first partial-thickness portion disposed between the first kiss-cut path and the second kiss-cut path; and a tamper-evident portion that remains adhered to the package side wall, the tamper-evident portion comprising a second partial-thickness portion disposed between the first kiss-cut path and the second kiss-cut path. 4. The system of claim 3 , wherein when the tear-away panel is torn away: the tear-away portion separates from the tamper-evident portion by creating a tear between the first kiss-cut path and the second kiss cut path, which exposes an interior of the paper forming the outer layer between the first kiss-cut path and the second kiss-cut path; and the hang tab sealing assembly separates into an upper portion and a lower portion, unsealing the package. 5. The system of claim 4 , wherein the exposed interior of the paper provides a visible indication that the package has been unsealed. 6. The system of claim 2 , wherein hang tab sealing assembly further comprises: a support layer entirely adhered between the outer layer and the inner layer, wherein the support layer has a third opening corresponding to the first and second openings, wherein the support layer has a thickness at least equal to that of package side wall. 7. The assembly of claim 1 , further comprising a third kiss-cut path extending on the lower surface of the tear-away panel parallel to the second kiss-cut path, wherein the third kiss-cut path is offset from the second kiss-cut path in the transverse direction away from the first kiss-cut path, and the first adhesive is entirely disposed between the third kiss-cut path and an edge of the tear-away panel. 8. The assembly of claim 1 , wherein the first and second kiss-cut paths are offset in the transverse direction by a distance within a range from 2 mm to 6 mm. 9. The assembly of claim 1 , wherein the tear-away panel comprises: a tear-away portion comprising a center portion extending at a center of the tear-away panel in the longitudinal direction bounded by the second kiss-cut path and a third kiss-cut path on the lower surface of the tear-away panel, wherein the center portion is configured to be entirely torn away when a user tears the tear-away portion away; and a tamper-evident portion extending in the longitudinal direction adjacent to the tear-away portion at each outer side of the center portion, wherein the tamper-evident portion is configured to separate from the remainder of the tear-away panel when the user tears the tearaway portion away, the separation occurring in the transverse direction between the first and second kiss-cut paths, and between the third kiss-cut path and an edge of the tear-away panel. 10. The assembly of claim 9 , wherein the tear-away portion further comprises peripheral portions disposed adjacent to the center portion, the peripheral portions configured to separate from the tamper-evident portions when the tear-away portion is torn away. 11. The assembly of claim 9 , wherein the tear-away panel comprises at least one grip portion integrally disposed at an end in the longitudinal direction, wherein the at least one grip portion is configured to be torn away with the tear-away portion in an integrated manner, and wherein the tear-away panel having the at least one grip portion has a length in the longitudinal direction greater than that of the hanging panel. 12. The assembly of claim 1 , further comprising: a paper support layer adhered between the outer layer and the inner layer, wherein the support layer has a third opening corresponding to the first and second openings. 13. The assembly of claim 1 , further comprising: a first removable protective liner detachably arranged to cover the first adhesive; and a second removable protective liner detachably arranged to cover the second adhesive. 14. The assembly of claim 1 , wherein the hanging and tear-away panels of the outer layer are integrally formed of a single layer of paper. 15. The assembly of claim 14 , wherein the single layer of paper is a multi-ply paper. 16. An apparatus for sealing a package, the apparatus comprising: a first panel formed of paper; a second panel formed of paper and extending from the first panel in a first direction in an integrated manner, wherein the second panel comprises at least one grip portion extending outward in a second direction perpendicular to the first direction; a primary kiss-cut path extending along a boundary between the first panel and the second panel at a first surface of the second panel and the first panel; and a pair of secondary kiss-cut paths extending on the second panel parallel to the primary kiss-cut path on a second surface of the second panel opposite the first surface, wherein the pair of secondary kiss-cut paths is offset from the primary kiss-cut path in the first direction. 17. The apparatus of claim 16 , further comprising: a first adhesive disposed on the second surface of the second panel, wherein the pair of secondary kiss-cut paths comprises a first secondary kiss-cut path and a second secondary kiss-cut path that is spaced apart from the first secondary kiss-cut path toward an outer edge of the second panel, and wherein the first adhesive is arranged entirely between the second seco
