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.
