Run the analysis to draft the report.
What are you packaging today?
Select your packaging type and upload your CAD or geometry file. I'll route the correct engineering workflow and ask only the next required question.
Supported formats: STEP, Parasolid (.x_t), STL, OBJ, GLB, DXF
Next: GeometryUpload your CAD so the analysis runs on the real model.
Upload the CAD.
STEP, STL, OBJ, GLB, PLY all accepted. The 3D viewer below mirrors what the analysis will run on.
Next: MaterialConfirm material properties and product inside.
Confirm material and product.
Verified material properties from the database. Anything missing is fetched on demand and cached.

Product inside
Tell us what's inside.
Next: TransitDeclare the route, road, and stack.
Declare the route.
Tell PackTwin where the shipment starts and ends. We infer the transport modes, leg durations and distance from lane data — you review, adjust if you know better, then approve.

Enter a pickup and destination above. PackTwin infers the modes, leg durations and distance so you don’t have to estimate hours by hand.

Did this match the real ISTA test?
Tell the analysis what actually happened. The platform learns where it was off and re-calibrates subsequent runs on this material × packaging-type pair.

Primary packaging — three alternatives, re-tested.
Pick an intent — cost, strength, or your own — and the optimiser proposes three alternatives, each re-evaluated through the same ISTA 2A pipeline.
The optimiser walks a protection ladder — tight wrap, dividers, cushioning, stronger board, fewer pallet layers, thicker film — and re-runs the biscuit trial after every rung until it passes your acceptance criteria. The first passing rung is recommended.
The optimiser walks a protection ladder — tighter carton, partition inserts, cushioning, stronger shipper board, fewer pallet layers — and re-runs the coil trial after every rung until it passes your acceptance criteria. The first passing rung is recommended.
Heatmap comparison · same drop, each variant
Scenario
Optimise the shipping carton.
The carton is graded by real McKee compression, drop safety factor, vibration dose, board cost, and carbon.
Optimised against the current primary (— g/unit).
Re-run if you change the primary.
