Mailer box
A mailer box is a packaging format commonly assembled from one blank with a hinged lid and interlocking walls or tabs.
What it means in packaging
Mailer designs vary. Many use corrugated board and folded wall sections, but the name does not guarantee that a particular pack is suitable for shipping without an outer carton. Closure security and cushioning are separate decisions.
A practical example
An apparel mailer can combine a hinged presentation lid with tissue, an insert and a shipping seal.
What to check
Test packed fit and closure security through the intended handling conditions before relying on it as a shipper.
