All the answers are here.

12 question clusters and 144 answers. These are organized around the actual questions customers ask before making decisions, rather than being arranged by holidays or aligned with trade shows.
Each response should address only one question; conclusions may be quoted directly.

CLUSTER 01

Can the structure be implemented?

How should the packaging structure be designed so that, after mold fabrication, you do not discover that the item cannot fit inside?

Can the structure be implemented? · Issue Cluster 01

The starting point for packaging structural design: Should the product be defined first, or should the box design be defined first?

Structural design should be developed by working backward from the physical dimensions of the product and its packaging method, rather than selecting the box type first; the box type is the outcome, not the starting point.
