Claim 17:
18. The coated substrate of claim 17, wherein the Cobb value of water absorption is less than or equal to 20 g/m2 per 30 minutes; and/or wherein the “kit level” oil and grease resistance, measured according to the TAPPI T559 test protocol, is equal to or greater than 6; and/or wherein a face-to-face heat seal, when made with a sealing bar at 160° C. and 40 psi for 1 sec provides adhesion to the extent of equal to or greater than 80% paper tear; and/or wherein a face-to-back heat seal, when made with a sealing bar at 160° C. and 40 psi for 1 sec provides adhesion to the extent of equal to or greater than 80% paper tear; and/or wherein a face-to-face heat seal, when made with a sealing bar at 121° C. and 50 psi for 3 sec provides adhesion to the extent of equal to or greater than 80% paper tear; and/or wherein a face-to-back heat seal, when made with a sealing bar at 121° C. and 50 psi for 3 sec provides adhesion to the extent of equal to or greater than 80% paper tear; and/or wherein when the coated samples placed face-to-back are conditioned at 50° C., 50 psi and 66% relative humidity (RH), provide roll block resistance to the extent of less than 80% paper tear.
