Packaging serves several important functions. It primarily refers to the container or wrapper for a product, and is an important part of marketing. There are three main types of packaging: primary for the immediate container, secondary for additional protection layers, and transportation for storing or moving multiple products together. Packaging protects products, promotes them, attracts customers, allows for easy identification and differentiation between products, and provides convenience. It prevents spoilage, breakage, damage and adulteration while allowing the product to be promoted and sold.
