T1 Single SKU
SmartPacker T1 plans how one type of carton fits into a single loading space: the full or remaining interior of a container, the area above a pallet, or a larger box that holds smaller cartons. Enter the length, width, and height of the loading space and the carton; T1 calculates a plan for the maximum quantity and shows it in a 3D viewer.
T3 Multi-SKU, Rotation Allowed
SmartPacker T3 is the standard edition for a known container space and a mixed cargo list: it works out which cargo-quantity combination can be loaded and shows how the resulting plan fits together. Unlike U3, T3 can rotate cargo through any of six orientations when the shipment allows it.
U3 Multi-SKU, Upright
SmartPacker U3 builds container loading plans for cartons and palletized unit loads. It computes a plan from cargo and container dimensions, then lets you edit it interactively when the actual loading job needs adjustment. Use U3 when the shipment contains multiple cargo types and the units must stay upright.
