ABSTRACT:
An adhesive coating which is pressure sealable to itself and non-blocking to a dissimilar coating is described. The coating comprises a blend of (a) a soft polymer having a measured glass transition temperature below room temperature; and (b) a hard polymer having a measured glass transition temperature which is above the measured glass transition temperature of the soft polymer (a). The soft polymer and the hard polymer are combined in a low blocking, pressure sealable coating formable proportion. A method of making the adhesive coating comprising the step of blending the soft polymer and the hard polymer and coated substrates formed from the adhesive coating are also described.
