The goal of secondary packaging is to ensure the integrity of a product during storage and transportation, making sure it reaches the hands of the user in the same state as it was made.

Rather than manually forming cases, which is inefficient and unergonomic, automatic case forming can make cases at a rate of 20 or more per minute. This allows for continuous case forming, a clear advantage for the customer. Once the case former is programmed, an employee simply loads case blanks into a magazine and the machine does the rest. Certain machines also have expandable magazines that allow it to be easily and continuously loaded on the fly for non-stop production.
