In-mold labels and a labeled container

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, the labels comprising:

• an adhesive layer having a front surface and a back surface, wherein the back surface of the adhesive layer is to be adhered directly to the outer peripheral wall;
• and
• at least one layer on the front surface of the adhesive layer,
• 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,
• wherein each of the depressed portions has a square shape in plan view and are surrounded by flat portions in a lattice pattern, because of the depressed portions, convex portions are formed at positions on the front surface corresponding to each depressed portion, so that the adhesive layer and the at least one layer have a concavo-convex structure, 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.
