Corrugated Spec Right-Sizer

Detect over-specified corrugated board and calculate the exact down-spec saving

Run this agent →

What it does

Submit your corrugated SKUs with current board spec, product weight, and stacking scenario. The Corrugated Spec Right-Sizer applies the McKee formula to calculate required BCT, compares it against your current spec's BCT, flags over-specified SKUs, and recommends the minimum-compliant board grade — with the annual saving per SKU from PackIndex CORR data.

Example use case

A manufacturer submits 4 corrugated SKUs. The Right-Sizer identifies that SKU-A (BC double-wall for a 3.2kg product stacked 4 layers, overwrapped) has a 2.1× over-spec factor. Downgrading to C-flute 125/112/125 still passes BCT with a 1.15× safety margin and saves 22% board cost — £38,000/year at current volume and PackIndex CORR pricing.

Frequently asked questions

What is the McKee formula?
BCT (kgf) = 5.876 × ECT × √(Caliper × Perimeter). The standard engineering approximation for corrugated box compression strength.
When should I not down-spec?
Cold chain, high-humidity environments, or fragile goods where BCT degradation risk is high. The agent flags these explicitly.
Does this require physical testing?
The agent recommends BCT physical testing (TAPPI T804 or ISO 12048) as a validation step before full rollout.
