The inner box should not shift, and supports should not crush its walls or lid. Validate the pack with the carrier's applicable test conditions.
Choose support that limits inner-box movement without point-loading its walls or lid. Check the closed pack in its intended carton and shipping configuration against carrier requirements or a validated packaging test. Record criteria, photos and outcome; a generic shake is not shipping approval.
Limit inner-box movement; tight filler can thin walls or press the lid.
Seat the box on flat support; check for a seam or void below.
Support all four sides; loose filler shifts, hard blocks load corners. Keep the lid area clear.
Define the pack test. Assess the closed pack against carrier conditions or validated packaging procedure. A generic shake is not approval.
