There is no magic formula, set template or proven algorithm for the creation of a powerful packaging design. Fortunately so, we say, or else the world would be a boring place. However, in this packaging blogpost, we aim to come as close as possible to offering such a recipe for success.

So, let’s assume you’ve successfully created an eye-catching packaging design with a distinctive brand asset. Now that your packaging has grabbed the consumer’s attention, its next job is to communicate.

What does it need to communicate? Simple: tell the consumer what your product is and why they should buy it. That’s it. Two questions only that your product packaging design has to answer.

Below, we’ve pulled together a list of all the ‘ingredients’ needed to answer these two questions. Be sure to then arrange these elements into a logical, easy-to-follow layout: our recipe for powerful packaging communication.


  • Category or product type
  • Brand
  • Variant: for products which offer more than one option
  • Functional benefit(s): what the product does
  • Reason(s)-to-believe: why the consumer should find the claimed functional benefit credible
  • Emotional end-promise or benefit: how the functional benefit fulfills a higher need
  • Call-to-action: why the consumer should buy it now
  • Size, weight, content details, etc.: practical information the consumer needs to know

How many of these ingredients have you included in your design? Probably not all of them. In fact, in our packaging design testing practice, we rarely see a product packaging that contains the full list of recipe ingredients. We have, however, noticed that designs which feature more of these ingredients tend to perform better.

We have seen a trend over the past years towards simplifying the ‘recipe’. For example, some product packaging designs communicate the promise, but not the benefit or reason-to-believe. The risk with such a minimalist design approach is that the more elements you leave out, the less likely consumers are to ‘get it’.

Minimalist design is great for the iPhone or speaker sets, but we find that packaged goods with a minimalistic design often struggle to effectively communicate to mass audiences. They more typically appeal to a niche audience and/or premium segments.


We’ve also noticed the benefit of illustrating the end-promise on the packaging. From shampoos promising beauty from shiny hair and skincare products offering eternal youth from radiant skin, to meal kits promising home bliss from a tasty homecooked meal, consumers are more easily persuaded by visual interpretations. Pictures, sketches, or structural shapes and lines offer powerful suggestion and emotional resonance.

The effective rendering of an emotional end-promise is a particular challenge for the newly emerging class of functional foods. A great example is the Brain Juice pack design, featuring an image of a brain that shines as bright as the sun. The Maca Sutra pack design on the other hand misses the opportunity to offer a visual interpretation of the powerful promise of sexual health  – or perhaps subtlety is what they were going for in this case.
