Packaging built around your product
Rigid cardboard envelopes protect flat products that should not bend easily in the postal network. They offer more structure than flexible mailers while keeping a slimmer shipping profile than many corrugated boxes.
The standard starting point is paperboard or micro-flute construction selected for the required stiffness in a flat rigid mailer with peel-and-seal flap and optional opening strip. Final material, dimensions, load performance, printing, and pack-out are confirmed against your samples or technical brief rather than assumed from a catalogue image.
