Labels with Adhesive Patch Patterns Optimized for Printer Applications

1 . A roll of linerless labels, comprising:

a substrate; and

an adhesive patch disposed on a backside of the substrate, wherein the adhesive patch disposed in a pattern of an adhesive on the backside, wherein the pattern repeats along the backside, and wherein the adhesive is a microsphere adhesive with a particle size of between 10-250 or 20-350 microns, wherein the pattern enables a consistent and continuous contact with a platen roller of a printer as the platen roller advances the label media through the printer to ensure consistent pull and energy exerted by the printer as the label media proceeds through a printer web path;

wherein the pattern minimizes adhesive buildup on components of the printer when the roll of labels is fed through the printer without decreasing adhesive bonding characteristics of labels dispensed from the printer.

2 . The roll of claim 1 , wherein the microsphere adhesive includes solids of at least 25%.

3 . The roll of claim 1 further comprising, a release coating applied atop a thermal print coating on a front side of the substrate, wherein the release coating comprises a water-based release coating, a silicone-based release coating, or a non-silicone based release coating.

4 . The roll of claim 1 , wherein the pattern includes 5 or more continuous stripes of the microsphere adhesive, each stripe separated by an area devoid of any adhesive.

5 . The roll of claim 1 , wherein the substrate comprises a stock weight of greater than or equal to 50 gsm (grams per square meter).

6 . The roll of claim 1 , wherein a coverage area of the microsphere adhesive within the pattern is between 30% and 70% of a total surface area of the backside that corresponds to any given label defined within the roll.

7 . The roll of claim 1 , wherein the pattern includes diamond shaped adhesive areas and diamond shaped void areas that are devoid of any adhesive.

8 . The roll of claim 1 , wherein the microsphere adhesive is an acrylic emulsion comprising microspheres in a solids range of at least 25%.

9 . The roll of claim 1 , wherein the adhesive patch comprises two adhesive patches vertically striped down the backside of the substrate, wherein a first adhesive patch is vertically striped adjacent to a first side of the backside of the substrate and a second adhesive patch is vertically striped adjacent to a second side of the backside of the substrate.

10 . The roll of claim 1 , wherein each label within the roll is repositionable based on the microsphere adhesive on a corresponding backside of a corresponding label.

11 . The roll of claim 1 , wherein the particle size is 10-250 microns, the microsphere adhesive is an acrylic emulsion with a solids ranges of greater than 25% and the substrate comprises a stock weight of more than 50 gsm (grams per square meter).

12 . The roll of claim 1 further comprising:

a thermally activated print coating on a front side of the substrate; and

a release coating disposed atop the thermally activated print coating.

13 . A linerless label, comprising:

a substrate; and

at least one adhesive patch disposed on a backside in a pattern, wherein the adhesive patch comprises an acrylic emulsion including microspheres with a solids ranges of at least 25% and a microsphere particle size of between 10-250 or 20-350 microns;

a thermally activated print coating disposed on a front side of the substrate;

a release coating disposed atop or over the thermally activated print coating;

wherein the pattern minimizes a coverage area of the acrylic emulsion along the backside of the substrate associated with the at least one adhesive patch and minimizes adhesive contact with components of a printer when the linerless label is fed through the printer;

wherein the adhesive patch enables a cutting mechanism of the printer to cut through the label substrate cleanly while minimizing adhesive debris on the cutting mechanism;

wherein the pattern and adhesive formulation provide characteristics for sufficient high tack and aggressive adhesives while mitigating printer adhesive buildup, jams and other printer malfunctions caused by adhesive buildup on printer components.

14 . The label of claim 13 , wherein the coverage area is between 30% and 70% of a total surface area of the backside of the linerless label.

15 . The label of claim 14 , wherein the substrate comprises a stock weight of greater than 50 gsm (grams per square meter).

16 . The label of claim 15 , wherein the at least one adhesive patch comprises a first adhesive patch and a second adhesive patch vertically striped along a first side and a second side of the backside of the substrate.
