PET sheets were surface‐modified by ion implantation from argon, nitrogen and hydrogen plasmas. The ion implantation was found to cause carbonization and cross‐linking, improving gas barrier properties against water vapor. The barrier effectivity improved with increased implanted ion fluence. The permeability changes and optical bandgap both depend on the ion species used during implantation. The lowest permeability was obtained using argon. For practical applications, the balance between gas barrier properties and photopic transparency is important. Our results show that argon implantation yields the lowest permeability with best retention of photopic transparency.
