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
Browse FEFCO-style structures, compare options, and generate a preliminary carton spec with material and case-fit guidance.
Next step
Case Builder
Generated specs pass the case-fit outside envelope into Case Builder and Packaging Systems.
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 Builder
Case Builder handoff preloads case dimensions for outer shipper planning.
Shipper Builder
Browse FEFCO-style corrugated shipper structures, compare options, and generate a preliminary outer shipper spec.
Next step
Box Strength/Performance
Generated specs can pass board grade, ECT, caliper, dimensions, and gross weight into Box Strength.
Box Strength/Performance
Estimate shipper compression strength and working loads using McKee/ECT, stack safety outputs, and environmental derating.
Next step
Pallet Calculator
Use "Send to Pallet Calculator" to carry your shipper dimensions into palletization.
Pallet Calculator
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 Calculator, 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.
