Packaging Design Mist Humidifier by Xiaochen Wang Mist is a humidifier whose packaging forms a working part of the product. The concept comes from a sealed plastic bag filled with air, where the air escapes when the bag is opened. Mist shows the amount of vapor visually through the size of the opening. The amount of vapor is controlled by pulling a trigger, instead of by electronic controls. The humidifier is made of ABS and PE plastic, and the white surfaces give a clean impression. Because the packaging is needed for use, the packaging is kept rather than discarded.
