Flex Packaging Fit Lab

Compare the current package against flexible mailers, padded mailers, rigid mailers, cartons, and multi-depth cartons. The lab estimates utilization, dimensional weight, labor, material cost, damage reserve, and annual savings without sending data anywhere.

    Calculation Notes

    DIM weight = package cubic inches / DIM divisor. Billable weight uses the higher of actual ship weight and DIM weight.

    Utilization compares modeled occupied product volume to package cubic volume. Very high utilization can increase pack risk for fragile items.

    Annual impact = current package cost minus recommended package cost, multiplied by monthly orders and 12 months.
