There are lots of different plastics. Lumping them all together shows
a general lack of understanding of the issue.

The current worries are the estrogenic chemicals Bisphenol A and
various phthalates. I think the "PBA" you quoted was probably intended
to be BPA.

Ziplock bags are made of LDPE and contain neither phthalates nor BPA.

Probably the biggest exposure you will get to BPA would be from cans
of soda, beer and food, that almost always have a plastic liner in the
inside, from your polycarbonate Nalgene bottle, and from handling the
thermal paper receipts you get when you buy stuff in town.

The clear PETE (polyethylene terephthalate) water bottles that most
people seem to use now contain phthalates, and may leach more when
they are exposed to the sun, or bounced around causing small hairline
fractures

I suppose you could carry your water in glass bottles.
