Fantastic idea- Looks great and can easily be incorporated into the way cappucino is sold and consumed. Looks like your design also offers retailers a way to personalize the cups with their brand logos. This is a strong marketing aspect. Elegant design!
Me again- Just read the thought from the Post-Landfill Action Network about the potential challenge of trying to use edible wrapping due to the hygiene problem. Is is still a problem to "double bag it"? The inside wrap is actually eaten and the outer is disposed. Even if it is not eaten, it is still biodegradable and a much better alternative to plastic, wax paper and other wraps currently in use.
