Abstract: A multilayer pressure-sensitive adhesive foam tape that includes: a pressure-sensitive adhesive polymeric foam layer having a first major surface and a second major surface, wherein the polymeric foam comprises: a poly(meth)acrylate derived from a (meth)acrylate-based (co)polymer component having a weight-average molecular weight (Mw) no greater than 500,000 g/mol and comprising at least one reactive functional group (X); and an optional additive selected from the group consisting of a density-reducing solid filler, a tackifier, a VOC scavenger, an odor absorber (particularly, activated carbon), a stabilizer, a rheological modifier, a thixotropic compound, and a combination thereof; a first pressure-sensitive adhesive skin layer adjacent the first major surface of the foam layer; and a second pressure-sensitive adhesive skin layer adjacent the second major surface of the foam layer.

Abstract: The disclosed adhesive eyelid closure article has a support layer and a pressure sensitive adhesive on the support layer. The support layer defines a main body and a non-adhesive tab area. The support layer has a central portion and an outer circumferential portion. The non-adhesive tab area is delimited by two recesses located in the outer circumferential portion of the support layer. The support layer has a first major surface and a second major surface opposite to the first major surface. The pressure sensitive adhesive is on at least part of the outer circumferential portion of the first major surface of the support layer, forming an adhesive coated area of the support layer.
