Market research can establish beyond the shadow of a doubt that the egg is a sad and sorry product and that it obviously will not continue to sell. Because after all, eggs wont stand up by themselves, they roll too easily, are too easily broken, require special packaging, look alike, are difficult to open, wont stack on the shelf.
- Robert Pliskin
Most packaging is designed to both sell the product inside and inform the customer about what it does and how to use it. It is one of the few places where sales/marketing text appears in the same piece as technical/instructional data.
