Industries where the packaging design is nearly identical is likely due to supplier limitations or governmental regulations or maybe that all of the ‘competing’ products are actually owned by the same parent company who find it more economical to print a universal box for all their products.

Whatever it may be, if you can differentiate your brand with package design, you should by all means.

But if your package cannot be redesigned to be distinguished from your competitors, then you’ll have to differentiate yourself in other ways.
