Plain-English explainers on the standards and test methods that decide these cases.
The corrugated industry's long-standing reference, compiling board grades, box styles, terminology, and engineering data.
A 1960s engineering estimate of a box's top-to-bottom compression strength from board ECT, caliper, and box perimeter.
Two non-interchangeable board ratings: Mullen (burst) measures puncture resistance; ECT measures edgewise compression (stacking) strength.
Column vs. interlocked stacking patterns, and the general trade-offs the packaging industry recognizes between them.
OSHA's powered industrial truck standard: operators must be trained, evaluated, and authorized for the specific truck type before operating.
Pick a 30-minute time that works for you. There's no charge for an initial consultation to discuss your packaging, warehouse, or load-securement matter and whether I'm the right expert for your case. Same-day conflict checks.
