What is the limitation regarding corner post insert formed edges?

The limitation regarding corner post insert formed edges primarily centers on how inserts interact with the overall structure of the container. When a corner post insert terminates on a formed edge, it can lead to issues with the integrity and strength of the container. Formed edges are treated as a critical structural element, and if an insert were to terminate there, it might create weak points where stress could concentrate, potentially leading to failures during handling or transport.

This is why it's essential for a corner post insert to avoid terminating on a formed edge, as doing so could compromise the intended structural reinforcement the inserts are meant to provide. Adhering to this limitation ensures that the container maintains its integrity, performance, and longevity throughout its use cycle. Thus, this understanding aligns with best practices in container construction and maintenance.
