Abstract

Security tapes are disclosed that include a first substrate having a first major surface covered with a first PSA, a plurality of discrete pieces of second substrate laminated to the first major surface of the first substrate by the first PSA, and a second PSA applied to each of the plurality of discrete pieces of second substrate on a first surface opposite the first substrate. The first substrate is continuous in both the machine and transverse directions. Each discrete piece of second substrate has a length oriented in the transverse direction and may be spaced a distance apart, in the machine direction, from each adjacent piece of second substrate. The first adhesion of the first PSA for each of the discrete pieces of second substrate is less than a second adhesion of the second PSA for a packaging material or packaging carton.

Claims (40)

1. A security tape comprising:

a backing having a first major surface and a second major surface;

a first adhesive applied to the second major surface of the backing;

a security layer adhered to the first adhesive, wherein the security layer includes a plurality of discrete pieces of paper oriented transverse to a machine direction of the security tape extending across the backing and between opposed edges of the backing, wherein each of the plurality of discrete pieces of paper is spaced a distance apart in the machine direction from each immediately adjacent one of the plurality of discrete pieces of paper;

a second adhesive applied to the security layer, wherein a first adhesion of the first adhesive between the backing and the security layer is less than a second adhesion of the second adhesive between the security layer and an adherend;

wherein the backing and the first adhesive are peelable away from the security layer after the tape is adhered to the adherend; and

wherein peeling the backing mars the first adhesive or leaves adhesive residue on the plurality of discrete pieces of paper which hinders replacement of the backing.

2. The security tape of claim 1 , wherein the distance apart is the width of a cutting blade.

3. The security tape of claim 1 , wherein the distance apart is less than 5 mm.

4. An adhesive security tape comprising:

a first substrate continuous in both a machine direction and a transverse direction and having a first major surface covered with a first pressure sensitive adhesive to form a subtape;

a plurality of discrete pieces of second substrate laminated to the first major surface of the first substrate by the first pressure sensitive adhesive, wherein each of the plurality of discrete pieces of second substrate have a length oriented in the transverse direction extending across the first substrate in the transverse direction and between opposed edges of the first substrate;

a second pressure sensitive adhesive applied to each of the plurality of discrete pieces of second substrate on a first surface opposite the first substrate to form a plurality of minitapes; and

wherein a first adhesion of the first pressure sensitive adhesive for each of the plurality of discrete pieces of second substrate is less than a second adhesion of the second pressure sensitive adhesive on each of the plurality of discrete pieces of second substrate for an adherend;

wherein the subtape is peelable away from the minitapes after the adhesive tape is adhered to the adherend; and

wherein peeling the subtape mars the first pressure sensitive adhesive or leaves adhesive residue on the minitapes which hinders replacement of the subtape.

5. The adhesive security tape of claim 4 , wherein each of the plurality of discrete pieces of second substrate are spaced a distance apart, in the machine direction, from each immediately adjacent discrete piece of second substrate.

6. The adhesive security tape of claim 4 , wherein the adherend is cardboard.

7. The adhesive security tape of claim 4 , wherein the first substrate is selected from the group consisting of biaxially oriented polypropylene, polyethylene terephthalate, unplasticized vinyl chloride, and polyethylene.

8. The adhesive security tape of claim 4 , wherein each of the plurality of discrete pieces of second substrate is a paper.

9. The adhesive security tape of claim 4 , wherein each of the plurality of discrete pieces of second substrate is a saturated paper.

10. The adhesive security tape of claim 4 , wherein each of the plurality of discrete pieces of second substrate includes one or more of a filament, fiber, or polymeric film.

11. The adhesive security tape of claim 4 , wherein the first substrate has a first release layer applied to a second major surface thereof, the second major surface facing in a direction opposite the first major surface.

12. The adhesive security tape of claim 4 , wherein each of the plurality of discrete pieces of second substrate has a second release layer applied to a second surface of the discrete piece of second substrate, said second surface facing towards the first substrate, wherein the second release layer is positioned between each of the plurality of discrete pieces of second substrate and the first adhesive.

13. The adhesive security tape of claim 4 , wherein the first major surface of the first substrate includes a low surface-energy indicia printed thereon such that removal of the first substrate from the plurality of discrete pieces of second substrate reveals the indicia in the form of the adhesive residue on one or more of the plurality of discrete pieces of second substrate.

14. The adhesive security tape of claim 4 , further comprising:

a taggant applied to one or more of the first substrate, the first pressure sensitive adhesive, one or more of the plurality of discrete pieces of second substrate, the second pressure sensitive adhesive, a first release coating, and a second release coating, wherein the taggant is identifiable through at least one of microscopy, fluorescence, and application of one or more frequencies of light and wherein the taggant is visible by a human eye.

15. The adhesive security tape of claim 4 , wherein the first substrate is a transparent film.

16. The adhesive security tape of claim 4 , wherein one or more of the plurality of discrete pieces of second substrate form a repeating pattern of one or more variations in shape, width, length, color, material, and topography.

17. The adhesive security tape of claim 4 , wherein, once the adhesive tape is applied to a seam of a cardboard carton, the first substrate is removable from the plurality of discrete pieces of second substrate without removing the plurality of discrete pieces of second substrate from the cardboard carton.

18. The adhesive security tape of claim 17 , wherein, upon removal of the first substrate, the plurality of discrete pieces of second substrate remain intact and adhered to the cardboard carton across the seam.

19. The adhesive security tape of claim 4 , wherein peeling the subtape mars the first pressure sensitive adhesive and leaves the adhesive residue on the minitapes which hinders the replacement of the subtape.

20. An adhesive security tape comprising:

a first substrate continuous in both a machine direction and a transverse direction and having a first major surface covered with a first pressure sensitive adhesive to form a subtape;

a plurality of discrete pieces of second substrate laminated to the first major surface of the first substrate by the first pressure sensitive adhesive, wherein each of the plurality of discrete pieces of second substrate have a length oriented in the transverse direction extending across the first substrate in the transverse direction and between opposed edges of the first substrate;

a second pressure sensitive adhesive applied to each of the plurality of discrete pieces of second substrate on a first surface opposite the first substrate to form a plurality of minitapes; and

wherein a first adhesion of the first pressure sensitive adhesive for each of the plurality of discrete pieces of second substrate is less than a second adhesion of the second pressure sensitive adhesive on each of the plurality of discrete pieces of second substrate for an adherend;

wherein the subtape is peelable away from the minitapes after the adhesive security tape is adhered to the adherend;

wherein peeling the subtape mars the first pressure sensitive adhesive or leaves adhesive residue on the minitapes which hinders replacement of the subtape; and

a taggant applied to one or more of the first substrate, the first adhesive, one or more of the plurality of discrete pieces of second substrate, the second adhesive, a first release coating, and a second release coating, wherein the taggant is identifiable through at least one of microscopy, fluorescence, and application of one or more frequencies of light.
