Packaging comparisons: flutes, grades, styles and carriers

Every comparison here is computed from the same data the calculators use, so the numbers on both sides are measured the same way.

Flutes

Thickness against print surface and space. Each pair shows caliper, outside size, McKee strength at the same ECT and boxes per pallet at five common sizes.

Board grades

What a step up in edge crush buys. Each pair estimates compression strength at ten sizes and how much of it survives storage time.

Box styles

How two FEFCO styles differ in closure, flap length and board used, drawn at the same inside size.

Carriers

Where two carriers bill the same box differently once their rounding and size thresholds are applied.
