LABELS WITH HOT MELT ADHESIVE PATCH PATTERNS
Labels with discontinuous hot melt adhesive patch patterns are provided. Hot melt adhesive is applied to a backside of a substrate for a given label in a discontinuous hot melt adhesive patch pattern. In an embodiment, the hot melt adhesive of a given discontinuous hot melt adhesive patch pattern is layered on the backside of a given label.
1 . A label, comprising:
a substrate; and
a discontinuous hot melt adhesive patch disposed in a pattern on a backside of the substrate.
2 . The label of claim 1 , wherein the the label is a linerless label.
3 . The label of claim 1 , wherein hot melt adhesive of the discontinuous hot melt adhesive patch is layered or stacked onto the backside of the substrate within at least a portion of the pattern.
4 . The label of claim 1 , wherein the pattern comprises a primary discontinuous pattern repeated and arranged in a secondary pattern on the backside of the substrate, wherein the secondary pattern is the pattern.
5 . The label of claim 4 , wherein the primary pattern is repeated and disposed on the backside of the substrate in the secondary pattern with one or more layers of hot melt adhesive stacked in portions of the secondary pattern.
6 . The label of claim 1 , wherein the pattern comprises at least two different primary discontinuous patterns repeated and arranged in a secondary pattern on the backside of the substrate, wherein the secondary pattern is the pattern.
7 . The label of claim 1 further comprising, additional discontinuous hot melt adhesive patches disposed in the pattern on the backside of the substrate.
8 . The label of claim 7 , wherein the discontinuous hot melt adhesive patch and the discontinuous hot melt adhesive patches are of a same shape.
9 . The label of claim 7 , wherein the discontinuous hot melt adhesive patch and the discontinuous hot melt adhesive patches are of different shapes.
10 . The label of claim 7 , wherein the pattern includes the discontinuous hot melt adhesive patch and the additional discontinuous hot melt adhesive patches that are bar shaped and separated by void areas that are devoid or any hot melt adhesive.
11 . The label of claim 7 , wherein pattern includes the discontinuous hot melt adhesive patch and the additional discontinuous hot melt adhesive patches that are circular shaped and separated by void areas that are devoid or any hot melt adhesive.
12 . The label of claim 7 , wherein pattern includes the discontinuous hot melt adhesive patch in a diamond shape and the additional discontinuous hot melt adhesive patches in triangular shapes and separated by void areas that are devoid or any hot melt adhesive.
13 . A roll of labels, comprising:
a substrate; and
at least one discontinuous hot melt adhesive patch disposed on a backside of at least one label of the substrate in a pattern, wherein the labels are defined and separated by sense marks disposed on the backside of the substrate.
14 . The roll of claim 13 , wherein each of the discontinuous hot melt adhesive patches include a repeated primary discontinuous hot melt adhesive pattern.
15 . The roll of claim 14 , wherein each of the discontinuous hot melt adhesive patches are disposed on the backside in predefined shapes within the pattern.
16 . The roll of claim 13 further comprising a continuous adhesive patch disposed on the backside of at least one additional label of the roll in a predefined shape.
17 . A method, comprising:
causing an applicator of a hot melt adhesive application station for a press to apply discontinuous hot melt adhesive patches to a backside of a substrate in a pattern as a web of the substrate is urged through the applicator; and
causing the web to urge to a next station of the press.
18 . The method of claim 17 , wherein causing the applicator further includes causing the applicator to oscillate creating variations in the pattern from label to label defined within the web.
19 . The method of claim 17 , wherein causing the applicator further includes causing the applicator to stack layers of hot melt adhesive within portions of the pattern within the discontinuous hot melt adhesive patches.
20 . The method of claim 17 , wherein causing the applicator further includes detecting locations along the web associated with labels defined within the web and activating the applicator to apply the discontinuous hot melt adhesive patches in the pattern onto the backside of the substrate at the locations.
