Adhesive label with water-based release coating
An adhesive label with a water-based release coating and methods for applying the water-based release coating to the adhesive label are provided. The water-based release coating is a non-silicon based formulation having a fluorochemical. The water-based release coating can be applied in a single-pass process or a double-pass process when manufacturing the adhesive label.

a front surface having a release coating applied to the front surface, the release coating comprising a formulation of a fluorochemical that is water miscible and includes a hydrophilic tail and a hydrophobic tail, wherein the hydrophilic tail is anchored into an underlying substrate of the adhesive label while the hydrophobic tail remains outside of the release coating; and
a second surface having an adhesive applied on at least a portion of the second surface.
2. The adhesive label of claim 1 , wherein the formulation is uniformly coated on all of the front surface.
3. The adhesive label of claim 1 , wherein the adhesive is applied in a pattern on the second surface.
