Exactly right, but that's also the challenge in and of itself.

How to make a container biodegradable, but not allow the contents of container to degrade it. Even slow degredation will cause a change in flavor for beverages, etc. (real quality issue) Many bottles are meant for very long shelf lives, so the degredation is a serious problem.

The corn and starch based plastics look very promising. I don't know, but probably the solution to them will be a sprayed in coating that only lets them degrade from the outside, much like a soda can.
