Food packaging refers to the materials used to enclose and protect food products. It serves several purposes, including preserving freshness, preventing contamination, and providing information about the product. Common packaging materials include plastic, glass, metal, and paper, each chosen based on the type of food and its storage needs. In addition to protection, food packaging often includes labels that provide important details such as ingredients, nutritional information, and expiration dates. This information helps consumers make informed choices about what they eat. Effective packaging also plays a role in marketing, attracting customers through design and branding.
