# Quick summary
# Why bigger boxes aren't safer Large empty spaces allow products to shift and gain momentum during transit. That movement is the primary cause of breakage. Measure products and aim for a box that leaves only an inch or two on each side for padding. The author shares a real example: circuit boards packed in oversized crates arrived destroyed because excess air didn't protect them.
# Match box strength to the load Corrugated board comes in single-wall, double-wall, and sometimes triple-wall. Heavy or dense items can crush single-wall boxes. Double-wall adds rigidity at modest extra cost and reduces returns tied to crushed cartons. Cost cutting on carton strength often backfires.
# Eliminate dangerous void space Shifting inside the box is the common failure mode. If you can shake a packed box and hear movement, add more fill. Crumpled craft paper is cited as a cheap, shape-holding void-fill that's easier for customers than polystyrene peanuts. Pack tight so contents can't slide.
# Secure seams and label clearly Cheap tape peels off in damp warehouses. Use good packing tape and the H-tape method: tape the main seam and both edge seams. Labels such as "Fragile" or "This Way Up" may not be read by everyone, but they help during handling and support insurance claims by documenting care taken.
# Design for stacking pressure Boxes are stacked on pallets, then loaded into trucks and left for days. If bottoms compress, pallets lean and can topple. Align box corners on the pallet—the corners carry vertical strength. Proper stacking and corner alignment preserve structural integrity.
# Implement moisture protection
# Practical trade-offs and cost perspective Investing slightly more in correct carton strength, good tape, and desiccants often saves time and money by cutting returns and rework. Cheap shortcuts—oversized boxes, weak tape, little or no moisture control—create recurring headaches.
# Bottom line Treat packing as an engineered step, not a hope-based afterthought. Measure, match board strength to weight, protect corners, eliminate voids, seal seams correctly, stack with corner alignment, and add moisture controls where climate varies. Those combined measures reduce breakage and customer returns.
