Label manufacturing method and label
A label manufacturing method including: applying an adhesive to a base sheet to form an adhesive layer; applying an acrylate-based bonding adhesive to part of the adhesive layer to cure the adhesive layer so as to form a cured portion; and cutting the cured portion to define labels. A label having an adhesive layer 12 laminated on a base sheet 13 . A part of the adhesive layer 12 is cured to form a cured portion 14, wherein the cured portion 14 is cured by an acrylate-based bonding adhesive for enabling cutting labels off the laminated base sheet.
1. A label manufacturing method comprising:
applying a first adhesive to a base sheet to form an adhesive layer;
partially applying a second adhesive which is an acrylate-based bonding adhesive to the applied first adhesive layer, on the same side of the base sheet as the first adhesive layer;
irradiating the first adhesive and the partially applied acrylate-based bonding adhesive applied to the first adhesive layer with an ultraviolet ray such that only the acrylate-based bonding adhesive is cured; and
cutting the base sheet where the acrylate-based bonding adhesive has been applied to define a separated label.
2. The label manufacturing method according to claim 1 , further comprising:
peeling-off waste by removing an unnecessary portion of the base sheet outward of the separated label.
3. The label manufacturing method according to claim 1 , wherein the acrylate-based bonding adhesive is a radical-polymerizable ultraviolet ray-curable composition.
4. The label manufacturing method according to claim 1 , wherein the first and second adhesives are different adhesives.
5. The label manufacturing method according to claim 1 , wherein the first adhesive is an adhesive based on synthetic rubber or natural rubber.
6. The label manufacturing method according to claim 1 , further including:
attaching a label separator to the adhesive layer, wherein the separated label is removably attached to the label separator.
7. A label manufacturing method comprising:
applying a first adhesive to a base sheet to form an adhesive layer;
separating a separator layer from the adhesive layer;
partially applying a second adhesive which is an acrylate-based bonding adhesive to the applied adhesive layer, on the same side of the base sheet as the adhesive layer;
irradiating the acrylate-based bonding adhesive applied to the adhesive layer with an ultraviolet ray;
adding the separator layer; and
cutting the base sheet where the acrylate-based bonding adhesive has been applied to define a separated label.
8. The label manufacturing method according to claim 7 , further comprising:
peeling-off waste by removing an unnecessary portion of the base sheet outward of the separated label.
9. The label manufacturing method according to claim 7 , wherein the acrylate-based bonding adhesive is a radical-polymerizable ultraviolet ray-curable composition.
10. The label manufacturing method according to claim 7 , wherein the first and second adhesives are different adhesives.
11. The label manufacturing method according to claim 7 , wherein the first adhesive is an adhesive based on synthetic rubber or natural rubber.
