Comment on More microplastics in glass bottles than plastic: study

The paint on the caps also had “tiny scratches, invisible to the naked eye, probably due to friction between the caps when there were stored.” This could then “release particles onto the surface of the caps”, it added.
I don’t really understand the contamination path.

I think what they mean is that the plastic caps were scratched up in storage before being applied to the bottles, so plastic dust on the inside of the cap before it was installed.
