Cardboard postal boxes are made for the unattended journey through a courier or postal network. They need a close fit so contents do not shift, a secure closure that survives handling, and, for many products, a depth that fits through a letterbox to avoid a failed first delivery. The whole point is surviving an unattended journey, so a secure close and a fit that resists movement come before anything cosmetic, though a tidy printed outer still reassures the customer that the order arrived as intended.
Fit and letterbox depth
Made to your custom size in corrugated cardboard, the box can be dimensioned to your product with a shallow profile where a letterbox-friendly delivery matters. Matching the internal size to the contents cuts the void fill you buy and the movement that causes damage in transit.
Closure and protection
- Internal size matched to the product
- A letterbox-friendly depth where it helps delivery
- A secure closure that holds through the network
If letterbox delivery is your aim, check the packed depth against the standard aperture with a prototype before you commit to a run. A letterbox-friendly depth can turn a failed first delivery into a successful one, so it is worth checking against the standard aperture.
