Some people seem to think that they're adding all sorts of crazy hazardous chemicals to water bottles, that are used for food, and contain a solvent.
The issue with water bottles is that some of them are oxygen permeable.
As to #7, all that means is "Other", which means it could be PET, and it could be a mixture of something else, but you don't know.
