Rigid mailers ship direct-to-consumer orders in self-locking corrugated boxes that fold shut without tape, cutting a step from the packing bench. Flute grade steps up with the shipped weight, interior and exterior faces both print full CMYK with Pantone PMS matching, and dimensions are cut to the product so the parcel carries little void fill. Recycled-content corrugated runs across the range, and a perforated tear strip opens the box cleanly.
Folded ears bite the walls, so no tape is drawn
Ridging graded from light goods to dense loads
Ink on inner and outer faces of every panel
Sizes cut close to the goods, trimming void fill
Recycled-content board across every size
No floor, so a first parcel run stays small
Rigid Mailers: Self-Locking E-Commerce Boxes
Why Self-Locking Matters at the Bench
A packer assembling a taped box handles a tape gun, a roll, and a blade for every parcel, and that time compounds across a shift. A self-locking mailer folds shut by hand, removing the tape step entirely and the consumable cost with it. Packify builds the locking ears into the dieline rather than as an add-on, so the closure holds through the parcel network without a strip of tape anywhere on the box.
Choosing a Flute Grade
Corrugated is not one material. A thin flute keeps a light apparel parcel cheap and crisp for printing, while a heavier flute carries dense goods without the walls bowing under a stacked pallet. Packify specifies the grade against the shipped weight rather than defaulting to one board for everything, which is the difference between a parcel that survives a sortation belt and one that arrives dented.
The Interior Is Free Brand Space
Every mailer already has an inside surface, and most brands ship it blank. Printing the reverse of each panel costs nothing structurally and delivers the entire brand moment at the instant a customer lifts the lid. Packify prints interior and exterior in the same pass, which is why a mailer is the cheapest unboxing photograph a direct-to-consumer brand will ever buy.
Right-Sizing Against Dim Weight
Carriers price parcels on dimensional weight, so a box larger than its contents is billed for air. Cutting the mailer to the product trims that billable volume and cuts the void fill needed to stop the goods rattling. Packify builds the dieline to the actual product footprint, and with no minimum a brand can run several sizes across a catalogue rather than forcing everything into one box.

Tuck Lock
Folded ears bite the walls so a parcel shuts by hand alone. No gun or roll is drawn. A bench packs faster per unit.
Flute Pick
Thin ridging suits light goods, thicker ridging carries dense loads. Grade tracks the weight shipped. Crush resistance follows the choice.
Inner Face
The reverse of every panel takes ink at no structural cost. Colour greets a customer mid-open. Photographs get taken and posted.
