1. A label, comprising:
a face layer, and
an adhesive layer,
wherein the face layer comprises semi-crystalline polymeric film, the adhesive layer consists of one or more adhesive sub-layers, a lowermost adhesive sub-layer of said adhesive sub-layers comprises transparent polymeric adhesive, the thickness of the face layer is in the range of 10 μm to 50 μm, the thickness of the adhesive layer is in the range of 8 μm to 25 μm, the thickness of the adhesive layer is smaller than 95% of the thickness of the face layer, an uppermost sub-layer of said adhesive sub-layers is in contact with the face layer, and the refractive index of the uppermost adhesive sub-layer is in the range of 80% to 98.5% of the refractive index of the semi-crystalline polymeric film;
wherein the label is attached to a release liner such that the adhesive layer is between the face layer and the release liner;
wherein the label is carried by the release layer, and the release value of the label is higher than 0.15 N in a situation where a sample piece of the label is separated from the release liner at an angle of 180° at a velocity of 1200 inches per minute at the temperature of 25° C., the width of said sample piece being equal to 2 inches.
