Combined surface treatments using plasma fluorination and surface roughening were applied to investigate whether they could increase the peel property of PET beyond the value needed for use as a release coating of pressure‐sensitive adhesive tapes. The peel strength of PET treated with CF 4 /He APG plasmas decreased to approximately 100 N · m −1 , but not quite to the ideal value of PTFE, 20 N · m −1 . We also prepared PET with a rough surface (matte PET) to examine the effect of surface roughening. The matte PET peel strengths were decreased by plasma fluorination; the roughest matte PET showed even lower peel strength than PTFE. We conclude that the combined treatments could be effective in the formation of a surface with high peel property on PET.
