A label sheet includes a transparent film support material, a pressure-sensitive adhesive layer, a release layer, a printable layer, one or more first detachment lines, and one or more second detachment lines. The transparent film support material has an inner surface and an outer surface. The pressure-sensitive adhesive layer is disposed over the transparent film support material inner surface. The release layer is disposed over the pressure-sensitive adhesive layer. The printable layer is disposed over the pressure-sensitive adhesive layer, and includes an inner surface facing the release layer and an opposing outer surface. The outer surface exhibits a roughness of 4 to 50 μm (DIN 4768). The one or more first detachment lines extend from the printable layer outer surface and through the printable layer and the release layer, to thereby form a first sub-region. The one or more second detachment lines extend from the support material outer surface and through the support material and the pressure-sensitive adhesive layer, to thereby form a second sub-region that is larger than the first sub-region.
1. A label, comprising:
a transparent film support material having an inner surface and an outer surface;
a first pressure-sensitive adhesive layer disposed over the transparent film support material inner surface;
a printable layer disposed at least partially over the first pressure-sensitive adhesive layer, the printable layer having an inner surface facing the first pressure-sensitive adhesive and an opposing outer surface, the inner surface exhibiting a roughness of 4 to 50 μm (DIN 4768);
a release layer disposed over the printable layer;
a polyethylene terephthalate (PET) film disposed between the release layer and the printable layer; and
a second pressure-sensitive adhesive layer disposed between the PET film and the printable layer.
2. The label of claim 1 , wherein one or both of the transparent film support material or the first pressure-sensitive adhesive comprise a light-absorbing component.
3. The label of claim 1 , wherein the printable layer inner surface exhibits a roughness of 10 to 25 μm.
4. The label of claim 1 , wherein the first pressure-sensitive adhesive layer is disposed in a pattern form that defines adhesive-free channels.
5. A label sheet, comprising:
a transparent film support material having an inner surface and an outer surface;
a first pressure-sensitive adhesive layer disposed over the transparent film support material inner surface;
a release layer disposed over the first pressure-sensitive adhesive layer;
a printable layer disposed over the first pressure-sensitive adhesive layer, the printable layer having an inner surface facing the release layer and an opposing outer surface, the outer surface exhibiting a roughness of 4 to 50 μm (DIN 4768);
a polyethylene terephthalate (PET) film disposed between the release layer and the printable layer;
a second pressure-sensitive adhesive layer disposed between the PET film and the printable layer;
one or more first detachment lines extending from the printable layer outer surface and through the printable layer, the second pressure-sensitive adhesive layer, the PET film and the release layer, to thereby form a first sub-region; and
one or more second detachment lines extending from the support material outer surface and through the support material and the first pressure-sensitive adhesive layer, to thereby form a second sub-region that is larger than the first sub-region.
6. The label sheet of claim 5 , wherein:
the label sheet includes one or more outer edges; and
said one or more second detachment lines are defined by the one or more outer edges of the label sheet.
7. The label sheet of claim 5 , wherein one or both of the transparent film support material or the first pressure-sensitive adhesive comprise a light-absorbing component.
8. The label sheet of claim 5 , wherein the printable layer outer surface exhibits a roughness of 10 to 25 μm.
9. The label sheet of claim 5 , wherein the first pressure-sensitive adhesive layer is disposed in a pattern form that defines adhesive-free channels.
10. The label sheet of claim 9 , wherein:
the label sheet includes one or more outer edges; and
the adhesive-free channels extend to the one or more outer edges.
