Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention particularly relates to a thermal label continuum without a backing sheet which is used by being set in a roll shape in a label printer, an automatic label sticking machine or the like.
[0002]
[Prior art]
In a continuous line of pressure-sensitive labels without a backing sheet, there is no band-shaped backing sheet on the back side of the label as in the past, and the pressure-sensitive adhesive is applied to the back side of the label. The surface comes into contact with the surface of the label, and has a draw-out (peeling) property and a defect that is not smooth even when transported inside the device.
[0003]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems and to provide a thermal label continuous body without a backing sheet which can smoothly feed out and transport a label.
[0004]
[Means for Solving the Problems]
In the thermal label continuous body without a mount of the present invention, a release agent layer made of silicon is formed on the surface of the belt-shaped thermal label base material, and a pressure-sensitive adhesive layer is formed on the back surface thereof. The pressure-sensitive adhesive layer is formed in a halftone dot shape with a mesh roller or a gravure roller, and the non-pressure-sensitive adhesive is buried in the recess, and a part of the pressure-sensitive pressure-sensitive adhesive layer is projected in the protrusion. It is formed to have low adhesive strength.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The heat-sensitive thermal label without a backing sheet of the present invention will be described with reference to FIG. 1 shown as a back view thereof, FIG. 2 which is a partial perspective view, and FIG. 3 which is a sectional view.
The thermosensitive coloring label 1 to which the mesh-shaped non-adhesive 6 shown in FIG. 1 is applied is wound in a roll shape with the back side inside.
Referring particularly to FIG. 3, a release material layer 3 such as silicon is applied to the front side of the thermal label base material 2 of the belt-shaped thermosensitive coloring label 1, and the entire surface of the thermal label base material 2 is coated on the back side. It has a pressure-sensitive adhesive layer 4.
[0006]
Next, on the surface of the pressure-sensitive adhesive layer 4, a non-adhesive 6 such as UV ink or UV varnish is formed in a mesh shape using a mesh roller or a gravure roller. Accordingly, this surface has a halftone dot irregularity as shown in FIGS. 2 and 3, reference numeral 5 denotes a recess, in which the non-adhesive 6 is buried, and the pressure-sensitive adhesive layer is formed. Since a part of 4 exhibits a protruding state, it has a weak adhesive force.
[0007]
Further, the non-adhesive 6 may be applied over the entire surface. In this case, by applying a thin coating, it is possible to obtain a weak adhesiveness as described above.
[0008]
【The invention's effect】
As described above, the present invention forms a release agent layer on the surface of a strip-shaped thermal label substrate, forms a pressure-sensitive adhesive layer on the back surface thereof, and then forms a non-adhesive layer of UV ink or UV varnish on a mesh roller or Since the gravure roller was formed into a halftone dot irregular shape, the non-adhesive was buried in the recess, and a part of the pressure-sensitive adhesive layer was formed in the protrusion in a protruding state. Adhesive strength can be reduced. Therefore, there is an advantage that the thermal label continuum without the backing sheet is excellent in peelability when being unwound from a roll-like wound state, and that the label transfer inside the apparatus is smooth.

Claims (1)

After forming a release agent layer made of silicon on the surface of the belt-shaped thermal label base material and forming a pressure-sensitive adhesive layer on the back surface, a non-adhesive layer made of UV ink or UV varnish is screened with a mesh roller or gravure roller. No mount is formed in the concave and convex shape, the non-adhesive is present in the recess in a buried state, and the pressure-sensitive adhesive layer is partially protruded in the convex and has a weak adhesive force . Thermal label continuum.
