Corrugated Mailer Boxes

When to Choose Corrugated Over Paperboard

Corrugated mailer boxes are the right choice when your products are heavy, fragile, or likely to face stacking and rough handling in transit.The fluted middle layer creates air pockets that absorb impact and spread out load forces, giving you more protection than single-ply paperboard at a similar weight.

Single-Wall vs. Double-Wall Construction

Single-wall corrugated suits lightweight products and standard e-commerce shipments where weight and cost are the primary drivers.Double-wall corrugated adds a second flute layer, increasing crush strength for bulkier or more delicate items that cannot afford damage in transit.

• Single-wall: everyday apparel, lightweight electronics, cosmetics kits
• Double-wall: heavy glass bottles, equipment, multiple items in one box
• Custom flute profiles: fine-flute for print quality, larger flutes for more cushioning

Balancing Protection, Weight, and Shipping Cost

Choosing the right corrugated spec is about more than strength alone. Over-engineering adds unnecessary material and postage cost, while under-engineering risks returns and replacements.We match flute type, wall count, and board weight to your products and carrier profile so you ship safely without paying for unused capacity.
