| Molded EPP box | The box will be handled, cleaned, returned, and reused on controlled regional routes. | Chamber, wall, lid, handles, divider, coolant slots, color, labels, and asset ID. | Loaded handling, cleaning, drying, stacking, return storage, seasonal packout, and retirement rules. |
| EPP with removable VIP liner | Impact protection, usable payload space, and replaceable insulation all matter. | Panel geometry, edge protection, liner retention, lid interface, chamber, and service access. | Panel protection, usable volume, cleaning boundaries, inspection, and replacement procedure. |
| Protected VIP shipper | High-value payloads, outer-size limits, long dwell, or demanding seasonal exposure justify higher-performance insulation. | Panel map, joints, lid, protective shell, coolant array, logger position, seal, and instructions. | Full and partial loads, summer and winter profiles, handling, panel inspection, and change control. |
| Collapsible VPU return box | Empty return volume matters and operators can repeat the foldable assembly correctly. | Fold lines, panel protection, closure, divider, coolant positions, return labels, and storage format. | Assembly repeatability, component inspection, cleaning, training, and return handling. |
