IN-MOLD LABELS AND A LABELED CONTAINER

摘要

A technical problem of this invention is to create in-mold labels that can be adhered to wide areas, including 3D curved areas, of the peripheral wall of a synthetic resin container in a high-grade state without air entrapment and/or wrinkling. A principal means of this invention to solve the technical problem described above is in-mold labels used as an inserted material and adhered to the outer peripheral wall of a container main-body concurrently when the main body is being molded, said labels including an adhesive layer to be adhered to the outer peripheral wall of the container main-body, wherein this adhesive layer has depressed portions on a back surface thereof, the depressed portions being formed by embossing and being disposed in a regular pattern.

1. In-mold labels used as an inserted material and adhered to an outer peripheral wall of a container main-body concurrently when the main body is being molded, said labels comprising an adhesive layer to be adhered directly to this outer peripheral wall, wherein the adhesive layer has depressed portions that are formed by embossing and are disposed in a regular pattern on a back surface of the adhesive layer, and wherein the depressed portions have:
an average depth in a range of 0.02 to 0.1 mm, an average number in a range of 25 to 2,500 per square cm of a unit surface area of a label, and a total of spatial volumes in a range of 0.001 to 0.005 cubic cm per square cm of the unit surface area of the label.
