1. A polymeric coating layer having a melt viscosity of about 1 Pa·s to about 1000 Pa·s measured at 300° C. and 1 rad/s, wherein the polymeric coating layer includes a continuous organic phase, with a particulate hydrophilic inorganic filler dispersed therein in an amount of about 10 wt % to about 70 wt %, the particulate hydrophilic inorganic filler being kaolin or a combination of kaolin and alumina trihydrate, the continuous organic phase comprising a hydrophobic polymer in an amount of at least about 70 wt %, based on the total weight of the continuous organic phase of the polymeric coating layer.
