Label with adhesive and silicone-free release coating
View Patent ↗A label having a silicone-free (water-based) release coating and compatible adhesive patch is provided. The label includes a thermally coated substrate having a silicone-free substrate overlaid thereon of a first surface. A second surface includes a microsphere adhesive layer.
1. A label comprising:
a substrate; and
a water-based release coating applied to a first surface of the substrate, wherein the water-based release coating is substantially free of silicone, the water-based release coating having silicone in an amount of 5% weight based on a total weight of the water-based release coating, and wherein the water-based release coating further includes a starch, a defoamer, a cross-linker, a fluorochemical, a non-silicone release agent and a catalyst; and
a microsphere adhesive applied to the second surface of the substrate, wherein the microsphere adhesive is repositionable and applied to the second surface in patches and with a coat weight of 9 gsm, wherein the starch from the water-based release coating ensures compatibility between the microsphere adhesive and the water-based release coating that form bonds between the microsphere adhesive and the starch.
2. The label of claim 1 , wherein the microsphere adhesive is applied to the second surface as two adhesive patches, the first adhesive patch applied to the second surface and the second adhesive patch applied over the first adhesive patch.
3. The label of claim 1 , wherein microsphere adhesive extends from one side of the substrate to a center line of the substrate on the second surface.
4. The label of claim 1 , wherein the substrate having a glossy top coat.
5. The label of claim 1 , wherein the water-based release coating is lane coated on the first surface.
6. The label of claim 1 , wherein the microsphere adhesive exhibits dissimilar qualities from the water-based release coating.
7. The label of claim 1 , wherein a viscosity of the water-based release coating is adjustable based on performance metrics of a press that applies the water-based release coating to the first surface of the substrate.
8. The label of claim 1 , wherein the microsphere adhesive is adapted to be dried on the second surface using one or more fans after each of one or more driers of a press that coats the water-based release coating and the microsphere adhesive on the first and second surfaces of the substrate.
