Paper, labels made therefrom and 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. A roll of paper, designed for one or more commercial printers, the paper
having a weight of less than about 70 gsm, and
having adhesive patches along the length of the roll to produce at least one repeat pattern in that direction;
each repeat pattern having a repeat length;
patches being separated by areas of material that has an affinity for the adhesive in the patches or areas of adhesive having a lower weight per unit area than that of the adhesive in the patches;
the spacing of the patches being configured to interact with a particular printer or printers having a platen roll to facilitate the passage of the paper through the printer(s),
the platen roll having a particular circumference;
the ratio of each repeat length to the circumference being not a whole number.
2. A roll as claimed in claim 1 , having one or two repeat lengths.
3. A roll as claimed in claim 1 , wherein each repeat length is less than the circumference.
4. A roll as claimed in claim 1 , wherein the circumference is one to two inches.
5. A roll as claimed in claim 1 , wherein the paper is thermal paper.
6. A roll as claimed in claim 1 , wherein the paper has a longitudinal axis extending along the center of the width of the paper and having a zone free of adhesive extending along the longitudinal axis.
7. A roll as claimed in claim 1 , wherein the paper has a longitudinal axis extending along the center of the width of the paper and wherein the adhesive in the patches is arranged in columns, the columns being parallel to and on both sides of the longitudinal axis.
8. A roll as claimed in claim 7 , wherein there are two columns, with one on either side of the longitudinal axis.
9. A roll as claimed in claim 1 , wherein the paper has a longitudinal axis extending along the center of the width of the paper and the adhesive patches are arranged at an angle of from about 20 to 70° to the longitudinal axis.
10. A roll as claimed in claim 9 , wherein the adhesive patches are arranged at an angle of about 45° to the longitudinal axis.
11. A roll as claimed in claim 1 , wherein the paper has a longitudinal axis extending along the center of the width of the paper and wherein the adhesive patches are arranged asymmetrically on either side of the longitudinal axis.
12. A roll as claimed in claim 1 , wherein the adhesive in the patches covers from about 65-85% of the linear length of the paper.
13. A roll as claimed in claim 1 , wherein the adhesive covers as least 60% of the width of the paper.
14. A roll as claimed in claim 13 , wherein the adhesive covers 75-80% of the width of the paper.
15. A roll as claimed in claim 1 , wherein the adhesive in the patches covers at least 40% of the surface area of the paper.
16. A roll as claimed in claim 15 , wherein the adhesive in the patches covers at least 60% of the surface area of the paper.
17. A roll as claimed in claim 1 , wherein the paper weight is from about 40to about 65 gsm.
18. A roll as claimed in claim 1 , wherein the paper weight is about 55 gsm.
19. A roll as claimed in claim 1 , wherein the areas of material that have the affinity for the adhesive in the patches comprise adhesive cleaning material.
20. A roll as claimed in claim 19 , wherein the cleaning material comprises at least one of polyvinyl acetate or titanium dioxide.
21. A roll as claimed in claim 1 , wherein the adhesive in the patches comprises a plurality of layers.
