Abstract

A combination closure tape and tear strip, an object comprising the combination closure tape and tear strip, and a method of sealing and later opening said object utilizing the combination closure tape and tear strip are disclosed.

Claims

1. An adhesive tape comprising:

a) a double-sided adhesive closure tape comprising a backing and pressure-sensitive adhesive applied to both sides of said backing;

b) a tear strip laminated onto one side of said double-sided adhesive closure tape; and

c) a release liner applied to said one side of said double-sided adhesive closure tape;

wherein the tear strip is laminated adjacent a first lateral edge of the closure tape and forms a tear strip region thereon, and wherein the width of the release liner extends from an opposite second lateral edge of the closure tape at least into a portion of the tear strip region.

2. The adhesive tape according to claim 1, wherein the tear strip is laminated adjacent a first lateral edge of the closure tape.

3. The adhesive tape according to claim 1, wherein the release liner extends from the second lateral edge to the first lateral edge of the closure tape.

4. The adhesive tape according to claim 1, wherein the tear strip forms a tear strip region on the closure tape, and wherein the width of the release liner extends from at least one lateral edge of the closure tape at least into a portion of the tear strip region.

5. The adhesive tape according to claim 4, wherein the release liner extends from both lateral edges of the closure tape.

6. The adhesive tape according to claim 5, wherein the release liner has a longitudinal split in the tear strip region.

7. The adhesive tape according to claim 1, wherein said backing is a tissue backing.

8. The adhesive tape according to claim 1, wherein said backing is an adhesive film backing.

9. The adhesive tape according to claim 1, wherein the width of the tear strip is less than the width of the double-sided adhesive closure tape.

10. A roll of adhesive tape according to claim 1.

11. A spool comprising a traverse-wound roll according to claim 7.

12. An envelope comprising an adhesive tape according to claim 1.

13. A box comprising an adhesive tape according to claim 1.

14. An adhesive tape comprising:

a) a double-sided adhesive closure tape comprising a backing and pressure-sensitive adhesive applied to both sides of said backing;

b) a tear strip laminated onto one side of said double-sided adhesive closure tape; and

c) a release liner applied to said one side of said double-sided adhesive closure tape;

wherein the tear strip forms a tear strip region on the closure tape, and wherein the width of the release liner extends from at least one lateral edge of the closure tape at least into a portion of the tear strip region.

15. The adhesive tape according to claim 14, wherein the tear strip is laminated adjacent a first lateral edge of the closure tape.

16. The adhesive tape according to claim 14, wherein the tear strip is laminated adjacent a first lateral edge of the closure tape and forms a tear strip region thereon, and wherein the width of the release liner extends from an opposite second lateral edge of the closure tape at least into a portion of the tear strip region.

17. The adhesive tape according to claim 14, wherein the release liner extends from the second lateral edge to the first lateral edge of the closure tape.

18. The adhesive tape according to claim 14, wherein the release liner extends from both lateral edges of the closure tape.

19. The adhesive tape according to claim 14, wherein the release liner has a longitudinal split in the tear strip region.

20. The adhesive tape according to claim 14, wherein said backing is a tissue backing.

21. The adhesive tape according to claim 14, wherein said backing is an adhesive film backing.

22. The adhesive tape according to claim 14, wherein the width of the tear strip is less than the width of the double-sided adhesive closure tape.

23. A roll of adhesive tape according to claim 14.

24. A spool comprising a traverse-wound roll according to claim 19.

25. An envelope comprising an adhesive tape according to claim 14.

26. A box comprising an adhesive tape according to claim 14.
