This document discusses packaging design and its various functions and types. It defines packaging as the science of enclosing products for distribution, storage, sale and use. Packaging serves important roles like product identification, protection, facilitating use, and promotion. There are three main types of packaging: primary, secondary, and transportation packaging. Primary packaging holds the product, secondary provides consumer information, and transportation packaging provides further protection for storage and transport. The benefits of packaging include improved appearance and shelf appeal, increased shelf life, reduced waste, and convenience. Packaging design must consider brand recognition, colors, shapes and other criteria. Trends in packaging reflect changing social and economic factors.
