Methods of making paper and labels
Paper is disclosed for use in making repositionable or removable adhesive labels. The adhesive can be applied in patches or discrete areas to the paper or to a layer of material that cleans rollers in the manufacturing line and/or in printers. The adhesive can be applied in single or multiple layers. The paper is light weight paper and preferably thermal paper for use in POS printers.
1. Paper for use as linerless adhesive labels in printers, the paper comprising:
a paper substrate having a width extending between lateral edges, a longitudinal axis extending along the center of the width, a first side and a second side;
the first side supporting at least one release layer;
the second side supporting at least one layer of adhesive;
at least one layer of material between the adhesive and the second side of the paper substrate, which aids in cleaning printer components when the labels are being printed;
wherein the adhesive layer comprises a plurality of substantially discrete adhesive areas containing a first adhesive, and a plurality of discrete adhesive areas containing a second adhesive; and
wherein the first adhesive is different from the second adhesive.
2. The paper of claim 1 wherein the discrete adhesive areas are arranged in the form of at least first and second columns.
3. The paper of claim 1 wherein the second adhesive is permanent adhesive.
4. The paper of claim 3 wherein the second adhesive is a low-tack permanent adhesive.
5. The paper of claim 3 wherein the first adhesive is a microsphere adhesive.
6. The paper of claim 2 wherein the substantially discrete areas of adhesive are in the form of three columns, the adhesive areas in at least one of the columns contains the first adhesive, and the adhesive areas in at least one of the columns contains the second adhesive.
7. The paper of claim 6 wherein the middle column contains the second adhesive.
8. The paper of claim 5 wherein the substantially discrete areas of adhesive are arranged in a diagonal pattern relative to the lateral edges.
9. The paper of claim 1 wherein the thicknesses of the first adhesive is different from the thickness of the second adhesive.
10. The paper of claim 8 wherein each pair of areas of the first adhesive are separated from each other by an area of the second adhesive, and wherein each pair of areas of the second adhesive are separated from each other by an area of the first adhesive.
11. The paper of claim 1 further comprising an adhesive free extending along one or both of the lateral edges of the paper.
12. The paper of claim 1 wherein the discrete adhesive areas of first and second adhesives are arranged at an angle to the longitudinal axis.
13. The paper for claim 12 wherein the angle of the adhesive areas is about 45 degrees.
14. Paper for use as linerless adhesive labels in printers, the paper comprising:
a paper substrate having a width extending between lateral edges, a longitudinal axis extending along the center of the width, a first side and a second side;
the first side supporting at least one release layer;
the second side supporting at least one layer of adhesive, the layer containing a plurality of substantially discrete adhesive areas;
at least one layer of material between the adhesive and the second side of the paper substrate, which aids in cleaning printer components when the labels are being printed;
wherein the adhesive layer comprises a plurality of first discrete adhesive areas having a first number of adhesive layers and a plurality of second discrete adhesive areas having a second number of adhesive layers; and
wherein the first number of adhesive layers and second number of adhesive layers are different.
15. The paper of claim 14 wherein the discrete adhesive areas are arranged in the form of at least first and second columns.
16. The paper of claim 14 wherein the plurality of second discrete adhesive areas is comprised of a permanent adhesive.
17. The paper of claim 16 wherein the second adhesive is a low-tack permanent adhesive.
18. The paper of claim 16 wherein the plurality of first discrete adhesive areas is comprised of a microsphere adhesive.
19. The paper of claim 15 wherein the substantially discrete areas of adhesive are in the form of three columns, the discrete adhesive areas in at least one of the columns contains fewer layers of adhesive, and the adhesive areas in at least one of the columns contains more layers of adhesive.
20. The paper of claim 19 wherein the discrete areas of adhesive in the middle column contains fewer layers of adhesive.
21. The paper of claim 18 wherein the substantially discrete areas of adhesive are arranged in a diagonal pattern relative to the lateral edges.
22. The paper of claim 14 wherein the thicknesses of the first adhesive is different from the thickness of the second adhesive.
23. The paper of claim 21 wherein each pair of areas of the first adhesive are separated from each other by an area of the second adhesive, and wherein each pair of areas of the second adhesive are separated from each other by an area of the first adhesive.
24. The paper of claim 19 further comprising an adhesive free extending along one or both of the lateral edges of the paper.
25. The paper of claim 24 wherein the discrete adhesive areas of first and second adhesives are arranged at an angle to the longitudinal axis.
26. The paper for claim 15 wherein the angle of the adhesive areas is about 45 degrees.
