Plastic that dissolves in water

Years ago I found corn starch "Styrofoam" packaging pellets that dissolved in any temperature water - as in - completely gone. Unfortunately I've had -0- luck finding it again.

This is a plastic bag that disappears in boiling water.

Check out the explanation about the dissolving plastic packaging at Creative Review.

The company behind the packaging and their blog.

So banning plastic bags near water like the Chesapeake Bay really isn't that much of a hassle with solutions like this eh?
