The present invention relates to a laminate for making adhesive labels and particular to a partially-secured shelf label and method of manufacturing the same.
Labels have been used in retail businesses for displaying product information and/or pricing to consumers. Many retail displays allow consumers to select the product and quantity they would like to purchase, and labels can be affixed to the display shelves to allow consumers to know pricing and other information relating to the product to be purchased. In some cases, products are moved, prices change or other information needs to be updated, and labels will be removed and a new label applied. In addition, the shelf will often have a finite thickness that provides limited space. Thus, some labels have been designed to secure partially to the shelf and include an area of deactivated or deadened adhesive that may hang down below the shelf. For example, such labels are shown in U.S. Pat. Nos. 6,579,585, and 6,926,942. Other examples of labels are shown in U.S. Pat. No. 8,261,477. All of these labels include a layer of adhesive over substantially the entire rear surface of the label and a deadening or deactivating agent applied selectively over such adhesive to create a label sheet that includes an active adhesive at a top (or side) edge and an inactive (deadened) adhesive at a bottom (or opposite side) edge.
Use of a deadening/deactivating agent provides a number of difficulties when manufacturing the label sheet and labels. Typically, a laminate will begin as an adhesive laminate containing no deadening agent. This laminate will be separated so that the face layer is pulled away from the liner such that the face layer and adhesive are on one side and the release/liner are on another side. The deadening agent is then applied either to the adhesive or to the release side and the two sections are re-laminated. Thus, in some cases, the use of a deadener requires a step of de-laminating an already made laminate to modify the properties thereof. Although other processes may be contemplated for manufacture of the labels having a deactivated or deadened adhesive section, these processes still require the use of an adhesive deactivating material, thus adding a material expense to the process.
This process is inefficient either due to the de-lamination and re-lamination processes, the use of a deactivating agent or both. Thus it is desirable to eliminate the need for an adhesive deadener or deactivating agent while still providing for an adhesive section and a non-adhesive section on the label.
Therefore it is an object of the invention to provide a laminate that allows adhesive to be selectively located on a label.
It is yet another object of the invention to provide a laminate for creating a shelf marking label that avoids the use of a deadening or deactivating agent.
It is yet a further object of the invention to provide a laminate that uses selectively applied release coatings to provide adhesive properties in sections of a label where such adhesive properties are desirable.
Yet further objects are to provide a label from the aforementioned laminate such that multiple discreet labels can be printed and then removed from the liner so that part of the label has adhesive thereon, and another part of the label does not include adhesive.
Still another object is to provide a laminate sheet that can be cut in to multiple discreet labels in a way that the non-adhesive section of the label will remain adhered to the liner during printing so as not to clog or damage the printer with adhesive.
These and other objects are achieved by providing a laminate including a face layer and a liner layer and a plurality of release coating sections. The release coating sections are selectively applied to the liner and the face layer, such that an adhesive layer disposed between the liner and face layers adheres to either the liner or the face layer in a section between the sections of release coatings when the face layer is removed from the liner layer.
In some aspects, a laminate includes a face layer and a liner layer. A plurality of release coating sections are selectively applied to the liner and the face layer, such that an adhesive layer disposed between the liner and face layers adheres to either the liner or the face layer in a section between the sections of release coatings when the face layer is removed from the liner layer. In other aspects, the laminate includes cuts in the face layer that terminate at the liner layer such that the cuts define a plurality of individual labels. In other aspects, the cuts are disposed such that each label includes a section of adhesive and a section of release coating, wherein part of the adhesive layer adheres to the face layer at the adhesive section and the adhesive section is disposed between two sections of release coating, one of the two sections of release coating is disposed on the label of the adhesive section, the other of the two sections of the release coating is disposed on an adjacent label.
In other aspects a label sheet includes a face layer and a liner layer. A first release coating section is applied to part of the face layer and is adjacent to an edge of the face layer. A second release coating section is applied to part of the liner layer and is adjacent to an opposite edge of the face layer. Adhesive is applied between the face layer and the liner layer such a first section of the adhesive adheres to the liner layer and a second section of the adhesive adheres to the face layer when the face and liner layers are separated.
In another aspect, a method of manufacturing a label is provided and includes one or more of the steps of (in no particular order): providing a face layer; providing a liner layer; applying a first release coating section to part of the face layer; applying a second release coating section to the liner layer; and laminating the face and liner layers by applying adhesive between the face and liner layers.
In some aspects, the method can include cutting the face layer to define a label such that when the label is removed from the liner layer, a section of adhesive is adjacent to a first edge of the label and a section of release coating is adjacent to an opposite edge of the label. In one aspect, the cutting step defines a cut extending through the face layer and terminating at the liner layer.
Other objects are achieved by providing a laminate including a face layer and a liner layer. An adhesive is disposed between the face and liner layers. A first section of release coating is applied to the face layer between the face layer and the adhesive and has a first width. A second section of release coating is applied to the liner layer parallel to the first section and disposed between the liner layer and the adhesive, the second section of release coating has a second width. A cut line extends into the face layer along an edge of the first section of release coating.
In some aspects part of the first and second sections of release coating extend along opposite sides of the cut line. In other aspects a common plane is defined by an edge of the first section of release coating and an edge of said second section of release coating and the cut line extends along the common plane. In other aspects the cut line includes a pair of cut lines spaced apart at a distance such that the first and second sections of release coating are located between the pair of cut lines.
In some aspects the adhesive includes a plurality of adhesive sections and the laminate includes a width of at least one of the plurality of adhesive sections being less than one of the first or second widths to define a void between the face and liner layers. The cut line extends through the face layer at the void. In other aspects the adhesive includes a plurality of adhesive sections and the laminate includes a first one of the plurality of adhesive sections disposed parallel to the first section of release coating and disposed between the second section of release coating and the face layer. A second one of the plurality of adhesive sections may be disposed parallel to the second section of release coating and disposed between the first section of release coating and the liner layer.
In yet other aspects the adhesive includes a plurality of adhesive sections and laminate includes a width of at least one of the plurality of adhesive sections being less than one of the first or second widths to define a void between the face and liner layers. In one aspect, the cut line may extend into the face layer at the void. In yet another aspect the cut line includes a pair of cut lines spaced apart at a distance such that the first and second sections of release coating are located between the pair of cut lines and two cut lines are spaced apart and extend between the pair of cut lines such that the two cut lines and the pair of cut lines define a perimeter of a label.
Other objects are achieved by providing a laminate including a face layer and a liner layer. A plurality of release coating sections are applied to the liner and the face layer such that at least two of the plurality of release coating sections are located on the face layer. The at least two of the plurality of release coating sections are spaced apart at a distance from each other to define a gap. Another one of said plurality of release coating sections is aligned with the gap. A section of adhesive is aligned with the gap and disposed between the face layer and the at least one of the plurality of release coating sections. A pair of cut lines extend into the face layer and are spaced apart at a distance such the section of adhesive and one of the plurality of release coating sections applied to the face layer are disposed between the pair of cut lines.
In one aspect a width of the section of adhesive is less than a width of said gap and a void is formed between adhesive and release sections. The cut line may extend through the face layer at the void. In other aspects one of the at least two of the plurality of release coating sections and the another one of the plurality of release coating sections each have an edge defining a plane, the one of the at least two of said plurality of release coating sections and the another one of the plurality of release coating sections extend in opposite directions from the plane.
In other aspects two cut lines are disposed at an angle relative to the pair of cut lines wherein the pair of cut lines intersect with the two cut lines to define a perimeter of a label. In other aspects the laminate includes printed indicia on an outer surface of the face layer. In some aspects the adhesive is a pressure sensitive adhesive. In other aspects the release coating comprises silicone.
Other objects are achieved by providing a method of manufacturing a laminate including one or more of the steps of: providing a face layer; providing a liner layer; applying a plurality of strips of release coating to the face and liner layers; applying a plurality of strips of adhesive to the face and liner layers; laminating the face and liner layers such that at least one adhesive strip of the face layer aligns with at least one of said plurality of strips of release coating applied to the liner layer; and cutting the face layer to define a pair of cut lines spaced apart such that the section of adhesive and one of the plurality of release coating sections applied to the face layer are disposed between the pair of cut lines.
In some aspects each one of the strips of adhesive of the face layer aligns with one of the strips of release coating. In other aspects a width of the strips of adhesive of the face layer is less than a width of the aligned strip of release coating of the liner layer such that a void is formed between the strips of adhesive of the face layer and the strips of release coating of the face layer. In other aspects the step of applying a plurality of release coatings defines at least one adhesive receiving section between two of said plurality of strips of release coating, at least one of the plurality of strips of adhesive applied to the at least one adhesive receiving section; and the cutting step further comprises cutting through the face layer at an angle relative to the pair of cut lines to define two of cut lines, the two cut lines extending between the pair of cut lines such that the pair of cut lines and the two cut lines define a perimeter of a label. In still other aspects the method may include cutting the face layer to define a label such that when the label is removed from the liner layer, a section of adhesive is adjacent to a first edge of the label and a section of release coating is adjacent to an opposite edge of the label. In yet other aspects the cutting step defines a cut extending through said face layer and terminating at the liner layer.

It is also contemplated that in an alternative embodiment that the selective application of release coating may be eliminated and adhesive is selectively applied in layers 20, 20′ as shown and described in
In some cases, the selective application of adhesive would be advantageous to pre-printed labels. In one embodiment, the graphics 10 could be applied to the face layer prior to the cutting into individual labels. For example, the face layer could be printed first or the laminate could be formed and the face layer could be printed after the laminate has been formed. Typically, cutting would need to take place after printing, because the cutting would cause the non-adhesive portions of the labels to hang from the laminate such that the labels and thus the adhesive could become caught in the printing press. However, it is contemplated that some printing presses could be configured to print label sheets according to
It may be advantageous that the adhesive be selectively applied to the face layer by only applying adhesive to sections of the face layer where needed. For example,
