|Several years ago, I came to the same conclusion as David Biddle and stopped using the word "plastics" to refer to that particular commodity in all its complex forms and subsets. Since then I've called this class of discards "polymers," because that's what they are: long carbon-based chains of repeating and interlocking molecular forms. Polymers differ greatly in characteristics such as look and feel, use, and biodegradability. Plastics are a subset of polymers.|
This nomenclature works for me.
And I know that cellwalls are polymers, etc., but hey, you gotta stop parsing words somewhere.
Or maybe not.

Mike's suggestions for resources are the best. I would caution, as most recycling professionals do, that there really is no such thing as "plastic." Plastics is a catch-all phrase for dozens of different petroleum-based resins. Each type has an entire economics and societal use and recycling application. PET and HDPE are the obvious resins to look at. PET seems to be particularly important these days since there's been such an increase in consumption and discarding of single-use water bottles. Along these lines, talking to end-users is paramount -- NAPCOR's membership list is a place to start: http://napcor.com/members.htm

Obviously, there are a lot of packaging companies you can contact and packaging industry trade groups.
Hope this helps.

Brenda, Joelle, I'd suggest checking out EPA Solid Waste
Characterization report, see http://www.epa.gov/epaoswer/non-hw/muncpl/pubs/mswchar05.pdf
specifically pages 47-51 which have some of the plastics recycling
numbers you're asking about. You should be able to get additional
information from Resource Recycling's "Plastics Recytcling Update",
You could also try contacting the association of Post Consumer
