Polymeric tape with tear cuts
A polymeric tape comprises a facestock extending lengthwise, the facestock including a polymer. An adhesive layer is on a first surface of the facestock. Tear-cuts are formed into at least one longitudinal edge of the facestock and extending inwardly, the tear-cuts being provided all along the at least one longitudinal edge of the facestock.
1. A polymeric tape comprising:

4. The polymeric tape according to claim 3 , wherein the support liner is wider than the facestock such that the support liner extends beyond at least one of the at least one longitudinal edge of the facestock widthwise.
5. The polymeric tape according to claim 2 , further comprising a low tack adhesive on a surface of the support liner opposite a surface having the adhesive layer.
6. The polymeric tape according to claim 2 , further including micro-perforations forming tear strips extending widthwise in the support liner.
7. The polymeric tape according to claim 6 , wherein the micro-perforations forming tear strips are aligned with tear cuts extending from at least one longitudinal edge of the support liner, and into the support liner.
8. The polymeric tape according to claim 6 , wherein the micro-perforations forming tear strips are aligned with the tear cuts in the facestock.
9. The polymeric tape according to claim 2 , including slits in the support liner.
10. The polymeric tape according to claim 2 , wherein the support liner is mounted to another support liner by another adhesive layer in a piggyback construction.
11. The polymeric tape according to claim 2 , wherein the support liner has a width that is equal to a width of the facestock.
12. The polymeric tape according to claim 1 , wherein the polymeric tape is a double-sided tape having another adhesive layer on a second surface of the facestock.
13. The polymeric tape according to claim 12 , further comprising at least one support liner releasably adhered to the adhesive layer and/or to the other adhesive layer.
14. The polymeric tape according to claim 13 , wherein a low tack adhesive is between the support liners of superposed sections of the polymeric tape.
15. The polymeric tape according to claim 14 , wherein the low tack adhesive is a strip that covers only a portion of a width of the support liners.
16. The polymeric tape according to claim 13 , wherein at least one of the support liners has tear-cuts.
17. The polymeric tape according to claim 1 , wherein adjacent tear-cuts are spaced apart by at most 6.5 mm.
18. The polymeric tape according to claim 1 , wherein the polymeric tape is wound into a roll.
19. The polymeric tape according to claim 1 , further comprising a support liner releasably adhered to the adhesive layer, and strips of perforations in the support liner only.
20. The polymeric tape according to claim 19 , wherein the strips of perforations are aligned with the tear cuts.
21. The polymeric tape according to claim 1 , wherein the tear-cuts are on both of the longitudinal edges of the facestock.
22. The polymeric tape according to claim 1 , wherein the facestock includes one or more of thermoplastic film, silicone rubber, metal foil, cloth, foam, cellulose fibers.
23. The polymeric tape according to claim 1 , wherein the adhesive layer is a static cling surface.
24. The polymeric tape according to claim 1 , wherein a portion of the adhesive layer along at least one of the longitudinal edges is neutralized.
25. The polymeric tape according to claim 1 , further including a varnish and/or an ink and/or an ink-receptive coating on the facestock.
26. The polymeric tape according to claim 1 , further including at least one electronic component in, under or on the facestock.
27. The polymeric tape according to claim 1 , further comprising a support liner releasably adhered to the adhesive layer, wherein the support liner is narrower than the facestock such that a narrow strip of the adhesive layer along the at least one longitudinal edge of the facestock is exposed.
28. The polymeric tape according to claim 1 , wherein the facestock has a thickness ranging between 0.4 and 12 mil.
29. A polymeric tape comprising:
a facestock extending lengthwise, the facestock including at least a polymer, the facestock having a thickness of 12 mil or less,
an adhesive layer on a first surface of the facestock, and
tear-cuts formed into at least one longitudinal edge of the facestock and extending inwardly, the tear-cuts being straight and being transverse to the at least one longitudinal edge, the tear-cuts being provided all along the at least one longitudinal edge of the facestock, the tear cuts being single slit cuts from the at least one longitudinal edge of the facestock, wherein the tear-cuts are the only penetrations in the facestock and are less than 8% of a total width of the facestock, and wherein adjacent tear-cuts are spaced apart by at most 6.5 mm.
30. The polymeric tape according to claim 29 , wherein the tear cuts penetrate from the at least one longitudinal edge of the facestock inwardly into the facestock by 0.01 mm to 3.00 mm.
