摘要： The present disclosure relates to an adhesive eyelid closure article comprising:
a) a support layer defining a main body and a non-adhesive tab area, wherein the support layer comprises a central portion and an outer circumferential portion, wherein the non-adhesive tab area is delimited by two recesses located in the outer circumferential portion of the support layer, wherein the support layer comprises a first major surface and a second major surface opposite to the first major surface; and
b) a pressure sensitive adhesive coating applied onto at least part of the outer circumferential portion of the first major surface of the support layer, in such a way as to form an adhesive coated area of the support layer.

摘要： The present disclosure relates to a silicone rubber foam layer obtainable by a process comprising the steps of:
a) providing a substrate;
b) providing a first solid film and applying it onto the substrate;
c) providing a coating tool provided with an upstream side and a downstream side, wherein the coating tool is offset from the substrate to form a gap normal to the surface of the substrate;
d) moving the first solid film relative to the coating tool in a downstream direction;
e) providing a curable and foamable precursor of the silicone rubber foam to the upstream side of the coating tool thereby coating the precursor of the silicone rubber foam through the gap as a layer onto the substrate provided with the first solid film;
f) providing a second solid film and applying it along the upstream side of the coating tool, such that the first solid film and the second solid film are applied simultaneously with the formation of the adjacent layer of the precursor of the silicone rubber foam;
g) foaming or allowing the precursor of the silicone rubber foam to foam;
h) curing or allowing the layer of the precursor of the silicone rubber foam to cure thereby forming the silicone rubber foam layer;
i) optionally, exposing the layer of the precursor of the silicone rubber foam to a thermal treatment; and
j) optionally, removing the first solid film and/or the second solid film from the silicone rubber foam layer.
