Edible wrap film made of milk protein
 China Color Masterbatch Trading Network: A group of American scientists have developed an edible film made of milk protein and believe that the film will appear on the shelf within three years. Edible packaging has appeared on the market today, but most of it is made of starch, which can be oxygen infiltrated. The food film is 500 times more efficient than existing packaging and is effective in isolating oxygen from food. Its main raw material is casein, a protein substance in milk, which means it can be biodegraded and eaten.

Peggy Tomasula, head of the study, said: "The film made of protein is effective against oxygen, textile foods rot, and can also be used to waste food when used as packaging."
