All Tools
PackCalc connects every packaging decision. Start with your product, work through to pallet—and see how each choice affects the next. No more isolated spreadsheets or retyping numbers between tools.
Carton Builder
Start from your product and get a recommended folding-carton style (FEFCO) and material grade, with clear “why” reasoning.
Next step
Case Builder
From results, you can hand off carton dimensions directly into Case Builder.
Case Builder
Figure out how your cartons fit into a case. Either fill a known case size or design a case for a target quantity. Your choice here affects shipper dimensions and pallet efficiency downstream.
Next step
Shipper/Box Builder
Use "Send to" to transfer the case to Shipper/Box Builder for shipper design.
Shipper/Box Builder
Define your outer shipper with FEFCO styles, board grades, and dimensions. Specs connect directly to strength validation and pallet planning downstream.
Next step
Box Strength/Performance
Use "Send to Strength" to prefill dimensions and material selections.
Box Strength/Performance
Validate your shipper against stacking loads using McKee/ECT, stack safety outputs, and environmental derating for more realistic margins.
Next step
Pallet Builder
Use "Send to Pallet Builder" to carry your shipper dimensions into palletization.
Pallet Builder
Generate and compare pallet patterns with 3D visualization. Comprehensive enough to find the optimal config, but not 199 options you'll never review. Connected to your shipper specs upstream.
Next step
Pallet Stability
From Pallet Builder, launch stability analysis to validate tilt thresholds direction-by-direction.
Pallet Stability
Check tilt stability using center-of-gravity geometry and compare against EN 12195-1 and EUMOS 40509 thresholds.
Supporting tools
These tools sit alongside the main workflow—use them whenever you need quick checks or environmental context.
Converters
