Packaging Box Common Structures: 8 Box Style Cross-Section Diagrams + Key Dimensions

Last week, a client came to me holding a box sample and asked: "What type of box is this? I want to make the same one."

I took one look and said: "This is a book-style box, with 2 inner pages and left-right flip covers."

The client was amazed: "You figured it out in 5 seconds?"

This is not a talent—it is a trained ability to "identify box types by looking at diagrams.". This article explains 8 common box types clearly using cross-section diagrams and key dimensions—after reading, you will also be able to identify box types in 5 seconds.
