Surface structures of poly(ethylene terephthalate) films produced by stretching after Ar plasma‐treatment were analyzed by X‐ray photoelectron spectroscopy, combined with a gas chemical modification technique, secondary ion mass spectrometry, and transmission electron microscopy. The formation of ultra‐fine protrusions that produce good slip and a smooth film surface after the stretching procedure was confirmed. The height of the protrusions was almost the same as the thickness of the osmic acid‐dyeable layer. The thickness of the modified layer was found to change according to the Ar pressure of the plasmatreatment. Carboxylic and hydroxyl groups produced by the plasma‐treatment were quantified. The formation of these functional groups can explain good adhesion of the film.
