A design concept can be thought of as a template for future packaging designs. This concept doesn't necessarily correspond to a unique product; rather, it involves the arrangement of assets, the use of logo, colors, and fonts.
A design adaptation refers to a specific design created for a particular product, including product-specific attributes such as its name, volume, standout features, and more. Furthermore, the layouts for different products, including label and box sizes, vary from one product to another.
Adapting the design means adjusting the product-related information and layouts accordingly.
