Mailer box, similar to FEFCO 0427

Structure and use

The mailer combines a base, tuck lid, and dust flaps. Double side walls fold over. Locking and thumb notch are parameters of the original construction.

You enter dimensions with a clear reference. The construction calculates creases and flaps using the selected material profile. Corrugated board needs a suitable thickness and allowance approach. A digital result does not replace an assembled prototype.

Our template

Inner printing and series sizes are use cases. Double walls require several creases and added compensation.

The template does not reproduce a standard drawing. An external reference classification and production approval are unconfirmed.

Deviations and pending confirmation

The assignment to similar FEFCO 0427 has not been confirmed by experts. Clarify flute direction and fit with your printer.

Flaps, slots and material behavior must be checked against the target material. Statements about fit remain starting values, not a guarantee.

The bundled material profiles are starting values and not calibrated. The app flags this with a finding of its own.

Reference provided for orientation. No standard texts or standard drawings are reproduced. Our constructions are original parametric templates; a reference does not confirm compliance with a standard.

For handoff

Check the sheet format with the manufacturability check and the layout with the up calculation. The printer receives separate production files as well as the report and manifest. An approval documents the status; it does not replace expert review.
