Shipping Boxes – FAQs
How does cardboard grade affect box strength?
Cardboard grade, including flute type and ECT rating, determines how well a box resists compression and deformation. Higher-grade corrugated cardboard supports heavier loads and stacked storage more effectively.
How do I choose the right shipping box for my product weight?
Match box strength to both product weight and shipping method. Lightweight parcel shipments can use standard single-wall boxes, while heavier or palletized shipments require higher ECT or double-wall construction.
Why do larger cardboard boxes require stronger board?
As box size increases, stacking strength decreases due to panel deflection. Larger cardboard cartons need stronger corrugated board to withstand compression forces during storage and transit.
How does box size impact dimensional weight charges?
Shipping carriers calculate dimensional weight based on box volume. Oversized shipping boxes increase costs even when the contents are light, making right-sized cartons critical for cost control.
How does moisture affect cardboard boxes during shipping?
Moisture weakens corrugated fibers and can significantly reduce box strength. In humid environments or long transit times, higher board grades and proper sealing are recommended.
When should double-wall shipping boxes be used?
Double-wall shipping boxes are ideal for heavy products, long-distance freight, palletized loads, or shipments exposed to higher stacking pressure.
What causes cardboard boxes to bulge or collapse?
Bulging occurs when internal weight or stacking pressure exceeds the cardboard’s strength. Proper board grade, correct sizing, void fill, and reinforced taping help prevent failure.
Does taping method affect shipping box performance?
Yes. Using reinforced sealing methods such as the H-seal improves shipping box durability by strengthening seams and reducing the risk of opening or collapse during transit.
