The packaging material is composed of polypropylene film, polyethylene film, paper, aluminum foil and multi-layer materials. When heated, water vapor condenses on the surface of the film and then is absorbed by the paper to avoid the purpose of soaking the food and maintain the prototype and original flavor of the food.
