Coating / packaging

While we are drinking yogurt、cheese or other similar beverages, lots of yogurt always adhere on walls of the container, thus resulting in a great waste. We can simply use a layer of glutinous rice paper.
In this way yogurt will not adhere to the wall of the bottle. We can easily fetch this film out and wrap it into a delicious yogurt cheese candy, that will both economize the beverage and make the containers easy to clean.
