Technical guides, validation standards, and industry papers for the modern packaging engineer.
What is DIM weight and how does it affect shipping costs? Learn the dimensional weight formula, UPS/FedEx/USPS divisors (139 vs 166), worked examples, and practical strategies to reduce billable weight through right-sized packaging.
How freight density (PCF) determines NMFC class and LTL rates, and how pallet optimization directly lowers shipping cost.
Practical guide to Cpk, AQL, and tolerance analysis for packaging specs. Why '10 inches +/- 1/8' hides real quality risk at scale.
The physics of pallet tipping: CG height, tilt angles, G-forces, stretch wrap, and how to verify stability before you ship.
How to choose a packaging safety factor without guessing, and why humidity, creep, and palletization quietly eat your strength margin.
Design packaging as one workflow (carton, case, strength, pallet, and testing) to reduce damage, redesign loops, and wasted cube.
Folding Cartons are for containment and presentation, not pallet stacking or distribution abuse. Learn limits, failure modes, and design red flags.
Why temperature and relative humidity alone confuse packaging test results, and why absolute humidity defines the real moisture risk.
The clear engineering difference between folding carton (paperboard) and corrugated board, and when to use each.
A technical guide to corrugated board grades, standard flutes (A, B, C, E), and how to specify ECT vs. Mullen burst strength.
Your box doesn't just 'ship.' It survives a specific lane. How to design different packs for Parcel (UPS/FedEx), LTL, and Full Truckload.
Stop drawing boxes on napkins. Use standard FEFCO codes (0201, 0427) to specify packaging styles instantly and globally.
Packaging cost isn't just price per box. It's labor, freight, and damage. Learn the 5 traps where saving pennies costs dollars.
A guide to understanding distribution testing: why it exists, how ASTM D4169 and ISTA work, what machines simulate, and how retailer/carrier specs fit.
Deep dive into paperboard grades: Solid Bleached Sulfate (SBS), Coated Unbleached Kraft (CUK), and Coated Recycled Board (CRB).
Corrugated strength comes from flutes + liners acting as a compression structure. Learn load paths, buckling, edge damage, and humidity effects.
An engineering framework for right-sizing corrugated cartons and shippers: when upgrading or downgrading strength reduces total cost, damage risk, and carbon.
How to run and interpret box compression testing: TAPPI T804, ASTM D642, McKee estimates, conditioning, and safety factors.
