Packaging serves several important purposes such as protecting products, providing information to consumers, and complementing promotional activities. There are three main levels of packaging - primary, secondary, and transport packaging. Primary packaging is what the customer directly handles, secondary provides additional information and layers of protection, and transport packaging is used for storage and distribution. Packaging plays a key role in reducing costs from breakage and damage, protecting products in transit and on shelves, and communicating useful details to consumers. Both Pizza Hut and KFC have taken steps to make their packaging more sustainable by reducing materials used and increasing recyclability.
