Stretch release article

摘要

Provided are adhesive articles and assemblies that include a flat and at least partially elastic backing along with a patterned adhesive coating on each side of the backing. When viewed from directions perpendicular to the backing, the adhesive on one side of the backing does not substantially overlap the adhesive on the opposing side of the backing. As a result, it is possible to use a stretch removable adhesive article that uses, for example, an aggressive adhesive to provide a reliable bond but still remove cleanly and easily from delicate substrates that would otherwise be damaged or destroyed if bonded with conventional adhesive constructions.

主权项

1. A dual-sided adhesive article comprising:
a flat and substantially elastic backing having first and second major surfaces; a first adhesive coating the first major surface according to a two-dimensional first pattern; and a second adhesive coating the second major surface according to a two-dimensional second pattern, wherein the first and second patterns do not substantially overlap with each other when the first and second patterns are projected onto a reference plane parallel to the backing, whereby areas of the backing coated by the first adhesive on the first major surface are substantially uncoated by the second adhesive on its opposing second major surface and areas of the backing coated by the second adhesive on the second major surface are substantially uncoated by the first adhesive on its opposing first major surface.
