Build packaging systems,
not scattered calculations.

Build from carton to pallet with linked outputs, validation checks, optimization, and reports.

Start a system See how it works
Carton
Primary pack dimensions
and material.
Case
Carton count and layout.
Shipper
Master box cube, weight, and strength.
Pallet
Pattern, load height, and utilization.
Validate
Strength, stability, and test-plan checks.
Optimize
Compare scenarios before committing.
Report
Traceable export with linked assumptions.

Worked example

One product, every step connected.

Follow one product through a complete packaging path. Each step's output becomes the next step's input.

  1. Carton
  2. Case
  3. Shipper
  4. Pallet
  5. Validation

Carton → Case → Shipper → Pallet → Validation

Each step shows what it produces first. The "Send to..." line shows exactly what data carries forward to the next tool.

Actions

Download a report, save to a project, or send to another tool.

The strip is shown open here as an illustration; on the actual tool page it behaves like the live result action menu.

Each step's output becomes the next step's input, and the next step is previewed so the chain stays connected.

Primary pack structure, material, and dimensions.

Start with the product and primary pack requirements. feeds the case pattern

Case Builder receives the carton as a physical item: case-fit OD, loaded weight, and units per carton.

Packaging Systems

The workflow becomes a system record.

Save the chain once, then use the same record for quantity planning, scenario comparison, validation evidence, and reports.

Saved system

4-Pack Retail SKU #1176

Validated Draft Partial Complete Validated
  1. Carton · Primary 4 units/carton 6.09 × 5.09 × 3.09 in
  2. Case · Secondary 6 cartons/case 24 units/case
  3. Shipper 24 units/shipper 16.23 lb · 32 ECT
  4. Pallet · Tertiary 32 shippers/pallet 768 units · 564 lb

Set one order quantity and the system rolls it up across the saved chain: units, cartons, shippers, full and partial pallets, weight, and cube.

Plan your quantities

Enter the total order quantity and see how it flows through your packaging system.

All calculations are saved with your system and can be edited anytime.

Start Anywhere

Use the tools standalone, or save the result into a system.

Many users arrive for one calculation. PackCalc lets that answer become the first reusable building block in a larger packaging workflow.
