The paper states:
> To such end, three teabags of different chemical compositions were used in this study: (1) empty nylon-6 (NY6) teabags (as a model of polyamide), (2) empty polypropylene (PP) teabags, and (3) commercially available teabags containing tea, and cellulose as the polymer composition.
To me, that suggests there were bags included containing no PP or Nylon-6.
