Abstract

An elongated length of a single or double-sided stretch releasing adhesive tape that can be cut to a selected length with integral pull tabs for stretch removing the tape from a substrate. The stretch releasing adhesive tape can be provided as long strips or roll form. The elongated stretch releasing adhesive tape article includes an elongate length of stretch releasing adhesive tape defining a longitudinal axis. The stretch releasing adhesive tape has a first surface and a second non-adhesive surface. The first surface comprises one or more adhesive regions and one or more non-adhesive regions arranged along the longitudinal axis. At least a portion of the non-adhesive regions comprise a series of pull tabs arranged along the longitudinal axis that can be grasped in combination with the second non-adhesive surface by a user during stretch removal of the tape from an associated substrate.

Claims

1. An elongated stretch releasing adhesive tape article that can be adhered to a substrate and subsequently removed by stretching comprising an elongate length of stretch releasing adhesive tape having a longitudinal axis, said stretch releasing adhesive tape having a first surface and a second surface, at least said first surface including at least one adhesive region, and at least one elongated non-adhesive region extending the entire length of said adhesive tape having a longitudinal axis parallel to said adhesive tape longitudinal axis, said non-adhesive region forming a pull tab along an end of said adhesive tape that can be grasped by a user to stretch remove the adhesive tape from an associated substrate.

2. The tape article of claim 1, wherein said at least one adhesive region is an elongated region having a longitudinal axis parallel to said adhesive tape longitudinal axis.

3. The tape article of claim 2, wherein said adhesive region is a single continuous strip extending the entire length of said adhesive tape.

4. The tape article of claim 1, wherein said non-adhesive region comprises an elongated non-adhesive region generally parallel to a first side edge of said stretch releasing adhesive tape and said adhesive region comprises an elongated adhesive region generally parallel to a second side edge of said stretch releasing adhesive tape.

5. The tape article of claim 1, wherein said non-adhesive region comprises an elongated non-adhesive region parallel to said adhesive tape longitudinal axis that is longitudinally interposed between a pair of elongated adhesive regions arranged generally parallel and adjacent to first and second side edges, respectively, of said stretch releasing adhesive tape.

6. The tape article of claim 1, wherein said at least one adhesive region comprises an elongated adhesive region extending the entire length of the adhesive tape parallel to said adhesive tape longitudinal axis and longitudinally interposed between a pair of elongated non-adhesive regions arranged generally parallel and adjacent to first and second side edges, respectively, of said stretch releasing adhesive tape.

7. The tape article of claims 1, wherein said first surface is releasably adhered to said second surface, thereby to form a roll of stretch releasing adhesive tape.

8. The tape article of claim 1, further comprising a liner releasably adhered to said first surface.

9. The tape article of claim 1, wherein said non-adhesive region comprises a gap in an adhesive defining said adhesive regions.

10. The tape article of claim 1, wherein said non-adhesive region comprises an appliques.

11. The tape article of claim 10, wherein said applique comprises one of film, paper, powder, foam, ink, or a release liner.

12. The tape article of claim 10, further comprising frangible connections formed intermittently along said stretch releasing adhesive tape and extending generally laterally from said adhesive tape longitudinal axis.

13. The tape article of claim 1, wherein said non-adhesive region comprises a single elongated non-adhesive region having a width less than the width of said adhesive tape.
