A Packaging Designer is responsible for the look and feel of a product, as the way a product is presented on the shelf is a huge factor in its purchase appeal.
A Packaging Designer needs to have a sense of what's on trend and a good understanding of what their client needs are. While style and design skills are important, so is a business sense to make sure the design outcome is cost effective.
A Packaging Designer may work within a packaging design studio, in-house within a company or on a freelance basis within various companies. They must have the ability to generate effective hand-drawn sketches and then use Illustrator and Photoshop and perhaps InDesign to combine typography, graphics and other design elements.
