Decide from the product and journey
Start with what the pack must hold, how it will be filled and what handling it receives before the customer opens it. A retail carton and an e-commerce mailer may carry the same product but solve different problems.
If the pack must also act as the shipping container, corrugated is often the first structure to evaluate. If it sits inside another shipper and presentation is primary, paperboard may be the clearer starting point.
