Product packaging design refers to the creation of the exterior of a product. That includes choices in material and form as well as graphics, colors and fonts that are used on wrapping, a box, a can, a bottle or any kind of container.
It’s a practical tool, yes. But it’s also more than that. Like any good design, packaging tells a story. It’s also a sensual experience, literally engaging us through sight, touch and sound (and possibly smell and taste, depending on the product/package). All of these details help us understand what the enclosed product is for, how it should be used, who should use it and, maybe most importantly, if we should buy a product or not.
