摘要：
The present invention relates to a label, the label comprising:
(a) a film having a first surface and a second surface and comprising a first film layer; and
(b) a pressure sensitive adhesive layer having a first surface and a second surface and comprising an adhesive wherein the first surface of the adhesive layer is adhered to the second surface of the film;
wherein the first film layer comprises at least one thermoplastic polymer, wherein the first film layer has a tensile modulus (ASTM D882) in a machine direction or a transverse direction of at least 900 MPa after immersion in water at a temperature of about 80°C for at least about 3 minutes, and the first film layer has an absolute areal dimensional change (ASTM D1204) of less than 5.0% after immersion in water at a temperature of about 80°C for at least about 3 minutes,
wherein the thermoplastic polymer of the first film layer comprises a polymer selected from the group consisting of a polyolefin, a (meth)acrylate polymer, a styrene polymer, a polyester, a halogen-containing polymer, a polycarbonate, a polyacrylonitrile, an aromatic polyether, an aromatic polyimide, an aromatic polyamide-imide, and a mixture of two or more of any of the foregoing polymers,
wherein the pressure sensitive adhesive exhibits at least one of a decrease in adhesion strength at temperatures above a room or ambient temperature, a decrease in adhesion strength on contact with an aqueous caustic solution, and combinations thereof,
wherein the label has an opacity of 12% or less, and
wherein the first film layer is nonoriented.
