FEFCO 0427: Roll end tray with locking cover
The roll end tray with locking cover is the die-cut mailer: a single die-cut piece with an unbroken bottom, double-thickness end walls rolled over from the base, and a lid that tucks and locks. It needs no tape to stay shut and opens like a presentation box.
Dieline
Construction
- One die-cut piece: base, front wall, rear wall, cover and a tuck flap on the cover.
- Each end wall is two panels deep. The outer panel folds up and the inner panel rolls over and down inside it, so the ends carry several layers.
- Dust flaps on the cover and rear wall close the corners; small locking tabs hold the rolled ends down.
| Part | Size |
|---|---|
| End walls | 2 × H, rolled |
| Cover | L × W, with tuck flap |
| Dust flaps | on cover and rear wall |
Closure. The tuck flap locks into the front wall. Tape or a tear strip is optional for parcel shipping.
Blank size
The die-cut blank is roughly (L + 4H) wide by (2W + 2H + tuck) long. The drawing is a schematic, not a production die.
When to use it
Good for
- Subscription and ecommerce mailers
- Printed presentation boxes
- Shallow products such as apparel, books and kits
Watch for
- Die-cut, so it needs tooling and costs more per box than an RSC at volume
- Best kept shallow; deep versions get floppy
Open the Spec Builder to check style, grade and dimensional weight for your product.
