Packaging has many approaches, two key areas that must be considered are functionality & differentiation. To create value packaging, you must look closely at the consumers.
Functionality includes primary requirements of packaging specific to the product, and performance needs. Science and Engineering play roles in the development of a package that takes the products from manufacturing to the consumer. (Structural Design)
The differentiation approach begins with understanding consumer behavior and designing a package that gives the consumer convenience, shelf appeal, and a unique experience.
Functional packaging focuses on basic requirements, differentiated packaging needs additional resources but brings more value to your customer.
