Abstract

To provide a plastic label having a sufficient antistatic property even when the plastic label has a printed layer formed from an aqueous ink. A plastic label including: a printed layer on one surface of a label base material including a plastic film; and an antistatic layer on the other surface thereof, wherein the printed layer is a printed layer formed from an aqueous ink, the antistatic layer contains an antistatic agent, and the antistatic layer has a surface resistivity of less than 1.0×10 12 Ω/□ under an atmosphere of 25° C. and 50% relative humidity after the printed layer and the antistatic layer are held in contact with each other at 0.025 MPa for 96 hours.

Claims (24)

1 . A plastic label comprising:

a label base material, including a plastic film;

a printed layer disposed on a first surface of the label base material; and

an antistatic layer disposed on a second surface the label base material, wherein

the printed layer is a printed layer formed from an aqueous ink,

the antistatic layer includes an antistatic agent, and

the antistatic layer has a surface resistivity of less than 1.0×10 12 Ω/□ under an atmosphere of 25° C. and 50% relative humidity after the printed layer and the antistatic layer are held in contact with each other at 0.025 MPa for 96 hours.

2 . The plastic label according to claim 1 , wherein

the antistatic agent includes an alkyl ammonium chloride.

3 . The plastic label according to claim 2 , wherein

the alkyl ammonium chloride has from 8 to 30 carbon atoms in a molecule.

4 . The plastic label according to claim 1 , wherein

the aqueous ink includes an acrylic aqueous resin or a urethane-based aqueous resin.

5 . A labeled container comprising:

the plastic label according to claim 1 ; and

a container body, wherein

the container body has a weight of 30 g or less, and

the label is attached to the container body.

6 . A method for manufacturing a labeled container, the method comprising:

preparing the plastic label according to claim 1 ;

attaching the plastic label to a container body; and

filling a content into the container body to which the plastic label is attached.

7 . The plastic label according to claim 1 , wherein the plastic label is configured to form a tubular plastic label, wherein with the plastic label formed into the tubular plastic label, the antistatic layer is on an outermost surface of the tubular plastic label.

8 . The plastic label according to claim 7 , wherein with the plastic label formed into the tubular plastic label, the printed layer is on an innermost surface of the tubular plastic label.
