Microstructured tape comprising coextensive, intersecting paint-retention and hand-tear patterns

摘要

Tape backings with a first major side and an oppositely-facing second major side, wherein the first major side includes coextensive, intersecting microstructured paint-retention and hand-tear patterns; and, tapes including such backings, and methods of making and using such tapes and tape backings.

主权项

1. A hand-tearable plastic tape, comprising;
a plastic backing comprising a longitudinal length and a longitudinal axis and a transverse width and transverse axis, and comprising a first major side and an oppositely-facing second major side,
wherein the first major side of the backing comprises a microstructured paint-retention pattern comprising microreceptacles that are at least partially defined by a multiplicity of first microstructured partitions and a multiplicity of second microstructured partitions at least some of which intersect with the first microstructured partitions to define microreceptacles thereby,
wherein at least some of the first microstructured partitions comprise first elongate ribs and wherein at least some of the second microstructured partitions comprise second elongate ribs;wherein the first major side of the backing also comprises a microstructured hand-tear pattern comprising a multiplicity of lines of weakness at least some of which comprise a long axis that is oriented at least generally transversely to the backing,
wherein the microstructured paint-retention pattern and the microstructured hand-tear pattern are coextensive and intersecting with each other,wherein at least some of the first elongate ribs comprise a multiplicity of notches, the notches being spaced down the length of the elongate rib with each notch being superimposed on a line of weakness at a point at which the first elongate rib traverses the line of weakness, and wherein each notch comprises a lowest point at which the local height of the first elongate rib is less than 60% of the height of the first elongate rib at a location proximate its intersection with a second elongate rib;and wherein a pressure-sensitive adhesive is disposed on the second major side of the backing.
