Abstract
The invention provides a biaxially-oriented polyester film that comprises a biaxially oriented polyethylene terephthalate film and contains 9000 ppm or less of ethylene terephthalate cyclic trimer, has a molten specific resistance of within 1.0×108Ω·cm, and at least one surface of the film has a surface resistivity of 13 log Ω or less under a relative humidity of 65%. The invention also provides a wrap-around label for a container produced from the film.
