Old packaging design typically featured more traditional and classic elements, such as intricate illustrations, ornate fonts, and muted colors. Modern packaging design, on the other hand, tends to be more minimalist, modern, and bold, with clean lines, flat graphics, and bright colors. Old packaging design often focused on providing detailed information and instructions, while modern packaging design emphasizes the aesthetics and visual appeal of the product. Additionally, old packaging design was often designed to be functional and protective, while modern packaging design is often designed to be attractive and engaging. Overall, the main differences between old and modern packaging design are in their aesthetic style and emphasis on visual appeal versus functionality.
