I often just use the container as a mold. I'll freeze the soup (or
whatever liquid) in the container, then pop the frozen block out of
the container and seal it up in a bag. Don't need as many containers
that way, and if you use a good quality bag with a decent seal, you
can do the "boil in bag" trick to reheat.

Thanks for all your input. A friend suggested that I line the plastic
containers with poly bags (made from polyethelene). There seems to be
no concern for this material. Then when the soup cools, pour the soup
into the poly lined containers and then freeze.
