Pressure-sensitive adhesive label

摘要

The present invention provides a novel pressure-sensitive adhesive label which curls little even under the coldest conditions and which has as a surface material a microporous stretched resin film obtained by stretching a crystalline polyolefin resin film containing an inorganic fine powder, a pressure-sensitive adhesive layer provided on one side of the surface material and a release paper provided on the pressure-sensitive adhesive layer, where the microporous stretched resin film satisfies the following physical properties (1) and (2): (1) the linear thermal expansion coefficient in a machine direction at -10 DEG C. (JIS K-7197) is from 10 to 70 mu m/mx DEG C.; and (2) the linear thermal expansion coefficient in the machine direction at 0 DEG C. is from 10 to 75 mu m/mx DEG C.
