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, STL, OBJ, GLB, DXF

Hello — I'm your packaging engineering assistant. Tell me what you're working on (a bottle, pouch, carton, can, etc.) and I'll guide you through the analysis.
Next: GeometryUpload your CAD so the analysis runs on the real model.
Stage 2 of 8

Upload the CAD.

STEP, STL, OBJ, GLB, PLY all accepted. The 3D viewer below mirrors what the analysis will run on.

No CAD on hand? Use a reference bottle (demo only)
Next: MaterialConfirm material properties and product inside.
Stage 3 of 8

Confirm material and product.

Verified material properties from the database. Anything missing is fetched on demand and cached.

Bottle material
Set a material in chat first.
Product inside
Tell us what's inside.
Next: TransitDeclare the route, road, and stack.
Stage 4 of 8

Declare the route.

Set how many hours the shipment spends in each transport mode, the worst-case manual-handling drop, and where it ships. Then approve to run the analysis.

Time in each mode (hours)

Manual handling
0 h

Route (stored with the case) Stack

Add at least one mode (hours) or a manual drop height to enable approval.

Next: AnalysisWatch the live run and review the plan detail.
Stage 5 of 8

Approve the plan, then run.

Every step labelled. Every assumption listed. Nothing runs without your sign-off.

Plan summary
Complete intake / geometry / material / transit first.

Edits above are saved with the case before the run starts.

Branch · Optimise

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.

PCR Intelligence

First alternative is always a post-consumer recycled swap

Each optimisation run pins the first variant to the PCR analogue of your baseline material (PET → PCR-PET, HDPE → PCR-HDPE, and so on). Mass and cost are recomputed against the recycled grade's density; the live carbon delta and recycled-content percentage appear inline once the run completes.

Product · Secondary packaging

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.
Document intake · step 1 of 2 · geometry

Upload your CAD geometry

Required first. The 3D model powers geometry analysis, the viewer, heatmaps, and geometry-based calculations. STEP, STP, STL, OBJ, or GLB.
