Packaging serves several important functions for products. It protects products, contains them, identifies brands, provides information to consumers, and promotes sales. Packaging design is an important part of a company's marketing strategy. Labels provide key details like ingredients, instructions, and warnings. Common label types include brand labels, descriptive labels, and grade labels. Packaging must safely contain products, define their identity, communicate necessary details to customers, meet consumer needs, and protect contents. Materials like glass, plastic, metal, and paper are widely used for their practical and economic benefits in food packaging.
