Process for printing wax release layer
View Patent ↗A wax printing process, apparatus, formulation, and label. The process includes contacting a wax formulation with a surface having at least one etched region thereon, and confronting a carrier with the surface such that at least a portion of the wax transfers from the etched surface to the carrier. The apparatus includes a tray and a manifold positioned in the tray. In another aspect, the apparatus includes a gravure sleeve and a heatable mandrel disposed inside the gravure sleeve. The wax formulation includes a paraffin wax, an ester wax, a hydrocarbon resin, a microcrystalline wax, and an ethylene-vinyl acetate copolymer resin. The label includes a carrier and a wax release layer confronting a surface of the carrier. The wax release layer confronts less that the entire surface of the carrier.
1. A label, comprising:
a carrier; and
at least one defined release pattern confronting a surface of the carrier, the at least one release pattern including wax;
wherein the at least one release pattern confronts less than substantially the entire surface of the carrier; and
wherein the wax is present in the at least one release pattern in an amount of 32% to 73% by weight.
2. The label of claim 1 , further comprising an ink design layer confronting the wax release layer.
3. The label of claim 2 , wherein the ink design layer conforms to the size and shape of the wax release layer.
4. The label of claim 2 , wherein the ink design layer includes an adhesive.
5. The label of claim 2 , further comprising an adhesive layer confronting the ink design layer.
6. The label of claim 2 , wherein the ink design layer includes at least one defined ink design.
7. The label of claim 6 , wherein the at least one release pattern is contoured in that an outer edge of the at least one release pattern conforms to an outer edge of the at least one ink design.
8. The label of claim 7 , wherein the at least one release pattern is larger in surface area than the at least one ink design.
9. The label of claim 7 , wherein the at least one release pattern is the same size in surface area as the at least one ink design.
10. The label of claim 6 , wherein the at least one release pattern is not contoured to an outer edge of the at least one ink design.
11. The label of claim 2 , wherein the at least one release pattern includes voids.
12. The label of claim 2 , wherein the at least one ink design includes voids.
13. The label of claim 1 , further comprising a plurality of defined release patterns confronting a surface of the carrier.
14. The label of claim 1 , wherein the wax includes a wax formulation including: a paraffin wax;
an ester wax;
a hydrocarbon resin;
a microcrystalline wax; and
an ethylene-vinyl acetate copolymer resin.
15. A label, comprising:
a carrier; and
at least one defined release pattern confronting a surface of the carrier, the at least one release pattern including wax;
wherein the at least one release pattern confronts less than substantially the entire surface of the carrier;
wherein the wax is part of a formulation including: a paraffin wax, an ester wax, a hydrocarbon resin, a microcrystalline wax, and an ethylene-vinyl acetate copolymer resin; and
wherein the paraffin wax is in an amount of 15% to 30% by weight, the ester wax is in an amount of 15% to 35% by weight, the hydrocarbon resin is in an amount of 15% to 50% by weight, the microcrystalline wax is in an amount of 2% to 8% by weight, and the ethylene-vinyl acetate copolymer resin is in an amount of 4% to 10% by weight.
16. The label of claim 15 , wherein the paraffin wax is in an amount of 28% by weight, the ester wax is in an amount of 26% by weight, the hydrocarbon resin is in an amount of 35% by weight, the microcrystalline wax is in an amount of 8% by weight, and the ethylene-vinyl acetate copolymer resin is in an amount of 3% by weight.
