Oh okay. But that would be as a packaging material, wouldn’t it? Plus, the bottles in question here, aren’t made of PE by itself. PE is translucent and soft. The other kind of polymer that’s brittle and transparent, is what’s mentioned in the article, IIRC.

Polycarbonate is mentioned - otherwise kind of known as plexiglas . Great for windows but no need to use it for food contact.
PE in its natural form is milk bottle plastic and is very safe.
