PROBLEM TO BE SOLVED: To create a label for in-mold molding capable of providing high-grade attachment to the wide area of a surrounding wall including a three-dimensional curved surface area of a synthetic resin container without the formation of air-pockets or wrinkles.SOLUTION: The label for in-mold molding which is used as an insert material and is attached to the surrounding wall of a synthetic resin container body at the same time when the container body is molded, includes an adhesion layer to be stuck to the surrounding wall of the container body. On a rear surface of the adhesion layer are embossed recessed portions that are regularly patterned. The average depth of the recessed portions is set within the range of 0.02 to 0.1 mm, and the average number of the recessed portions per 1 cmon a label surface area is set within the range of 25 to 2500. Furthermore, the total spatial volume of the recessed portions per 1 cmon the label surface area is set within the range of 0.001 to 0.005 cm. |
