Abstract

Claims (31)

1. The process for forming a peelable label comprising the steps of:

providing a primary label web having a first and second side;

forming a release layer on the first side of said primary label web;

printing indicia on said release layer on said first side primary label;

while printing indicia on said second side of said primary label web in one press pass in a printing station in such a manner that said indicia on said release layer is in registry with said indicia on said second;

providing a secondary label web;

further comprising the step of printing indicia on at least one side of said secondary label web prior to forming a pressure sensitive tacky adhesive layer on a side of said secondary label web;

forming a pressure sensitive tacky adhesive layer on a side of said secondary label web;

laminating said release layer of said primary label web to said pressure sensitive tacky adhesive layer disposed on said secondary label web to form a single web; and

cutting said single web to form individual peelable labels, wherein said indicia on said release layer is transferable to said pressure sensitive adhesive layer upon separation of said primary label from said secondary label.

2. The process according to claim 1 further comprising the step of printing indicia on at least one side of said secondary label web prior to forming a pressure sensitive tacky adhesive layer on a side of said secondary label web.

3. A process according to claim 1 further comprising printing indicia on said release layer in reverse.

4. The process according to claim 1 wherein said primary label is a substrate selected from the group consisting of paper, polymer and a mixture of paper and polymer.

5. The process according to claim 1 wherein said secondary label is a substrate selected from the group consisting of paper, polymer and a mixture of paper and polymer.

6. The process according to claim 1 wherein the amount of pressure sensitive adhesive is minimized to the lowest coated weight possible to maintain adhesion between said primary and secondary labels.

7. The process according to claim 1 wherein said pressure sensitive adhesive is a carboxylated acrylic and further comprises a crosslinking agent.

8. The process to claim 1 wherein the indicia comprises ink.

9. The process according to claim 1 wherein the primary label further comprises indicia disposed in reverse on said release layer on said first side and indicia disposed on a second side such that upon separation of the primary label from secondary label the indicia disposed in reverse on said release layer will be transferred to the pressure sensitive adhesive on the secondary label.

10. The process to claim 1 further comprising adhering a second side of said secondary label to an object to be labeled wherein the adhesion of the secondary label to the labeled article is greater than adhesion of the primary label to the secondary label.

11. The process to claim 10 wherein said secondary label is adhered to the object to be labeled using and adhesive selected from the group consisting of wet labeling glues, heat activated adhesives and pressure sensitive adhesives.

12. A process for forming a peelable label comprising the steps of:

providing a primary label web having a first and second side; forming a release layer on the first side of said primary label web;

forming a protective layer on said release layer;

printing indicia on said protective layer;

printing indicia on said second side of said primary label web in on press pass in a printing station;

providing a secondary label web;

further comprising the step of printing indicia on at least one side of said secondary label web prior to forming a pressure sensitive tacky adhesive layer on a side of said secondary label web;

forming a pressure sensitive tacky adhesive layer on a side of said secondary label web;

laminating said protective layer of said primary label web to said pressure sensitive tacky adhesive layer disposed on said secondary label web to form a single web; and

cutting said single web to form individual peelable labels wherein said indicia on said protective layer is transferable to said pressure sensitive adhesive layer upon separation of said primary label from said secondary label.

13. The process according to claim 12 , further comprising printing indicia on said protective layer in reverse.
