Japan develops a fast-cooked food package that protects food from water vapour soaking in food

Japan develops fast-food packaging that prevents water vapor from soaking food. The packaging material is composed of polypropylene film, polyethylene film, paper, and aluminum foil. When heated, water vapor condenses on the surface of the film and is absorbed by the paper. Avoid the purpose of soaking the food and maintain the prototype and original flavor of the food.
