Claims14
A reinforced substrate for application to skin, comprising:
- a transparent backing having a first major surface and a second major surface, opposite the first major surface, wherein the transparent backing comprises a film comprising a material selected from the group consisting of polyurethane, polyester, and polyether;
- a transparent reinforcing material that is less extensible than the transparent backing and comprises a grid forming multiple open areas, wherein the transparent reinforcing material comprises a first planar surface and a second planar surface opposing the first planar surface and adjacent to the first major surface of the transparent backing;
- and
- an adhesive on the first major surface of the transparent backing and the first planar surface of the transparent reinforcing material;
- wherein the reinforced substrate has a moisture vapor transmission rate (MVTR) of at least 250 g/m2/24 hrs/37 degrees C./100-10% RH using the inverted cup method;
- and
- wherein the reinforced substrate has a percent luminous transmission (% T) over at least a portion of the visible light spectrum (400 to 700 nm) of at least 50%, a haze of between 10% and 60%, and a clarity of at least 20%.
