A packaging range has two jobs that can pull in different directions. It needs to feel like a family, while helping people distinguish one product from another.

Across the Purina Pro Plan packaging, the brand identity and overall layout remain consistent, while product names, colours, cat imagery and supporting panels vary. Together, the packshots offer a useful way to explore the decisions a packaging brief should settle.

1. Which cues are fixed across the range?

A brand mark, layout or other repeated visual element can help connect products as a family. The brief should identify which cues need to remain consistent across the range.

2. What needs to change for each product?

Variant names, colours and imagery can help distinguish products. The brief should clarify which differences matter to the customer, and how they should be expressed without losing the connection to the wider range.

3. What should be understood at a glance, and what can be read more closely?

Not every detail can lead. Decide what people need to recognise first, what helps them compare options, and what supporting information needs to remain available. Required product copy should be confirmed by the relevant client reviewers.

4. Where will the packaging be seen?

A pack may appear on a shelf, in a product listing or in other marketing materials. The brief should identify which parts of the system need to remain clear across those contexts, and where the design may need to adapt.

5. Who decides when priorities compete?

Marketing, product, sales, operations and regulatory reviewers may all have useful input. Agree which requirements are non-negotiable, who approves product information, and how concepts will be assessed against the brief. Otherwise, each review can introduce another priority without resolving the trade-offs.

A packaging brief does more than list what belongs on the pack. It defines the rules of the system: what holds the range together, what distinguishes each product, and how the team will make choices when those goals compete.

The question to settle before design begins is simple: what should stay consistent, and what must change?
