The design of packaging visuals can be tested and modeled out in many ways
The most popular solution is the so-called dummy packages. With dummies the designed visual is made into a physical model package. Dummies are often used in structural testing to verify that the design and layout work seamlessly together. Dummies are also used in advertising and pre-marketing actions when a physical model of a product that is not yet available.
Another popular way to model a packaging visual is through mock-up images
Mock-ups are edited product illustrations, that can be used to either test the functionality of an individual package, or to check the design for full category compatibility. For example, we can create an image of a store shelf in which mock-up images of the entire product family are placed, as well as add the visuals of point of sale materials. In this way, the structural image of the shelf can be easily changed and different solutions can be tried out in order to obtain the best attention value.
