Stacked cardboard boxes for ecommerce shipping and storage

Mailer boxes

Mailer boxes are corrugated structures designed for direct shipping and unboxing. They can carry print inside and outside, and they provide better courier protection than a common retail carton.

Folding cartons

Folding cartons are efficient retail boxes. They ship flat, store well and carry detailed product information, but they usually need an outer carton or mailer for ecommerce delivery.

Cost and freight

A folding carton may have a lower unit price, but a mailer can sometimes replace an additional shipper. Compare the full packing solution, including freight volume and damage risk.

Practical recommendation

Use mailer boxes when the package ships directly to customers. Use folding cartons when shelf display and flat packed efficiency are more important.
