How the shape is constructed
The base is in the centre of the blank. Double side walls fold over and are held by locking tabs in the base; ears and dust flaps close the side openings. A thumb notch makes the tuck lid easier to access.
How it is assembled
Raise the front and back walls and fold the ears inward. Raise the side walls over them, fold the rollover inward and insert the tabs into the base slots. After filling, close the lid, fold in the dust flaps and insert the tuck flap.
Material and grain direction
Grain direction vertical on the blank (check)
Test fit, folding and closure on a sample made from the intended material. Confirm material thickness, grain direction and production steps with your printer.

Inside dimension
These dimensions describe the preview, not a fixed packaging size. The app recalculates the dieline for your own dimensions.
What to consider for this construction
Flap gap
Gap between adjacent flaps or walls; at least about the material thickness.
Ear length (ratio)
Length of the ears or corner flaps as a proportion of half the inside width.
Lid dust flaps (ratio)
Length of the lid dust flaps as a proportion of the inside height.
Dust flap angle
Angle of the dust flaps (also the ears on a mailer); larger angles prevent collisions during folding.
Frequently asked questions
Which flute is suitable for the mailer?
The catalogue example specifies E-flute or microflute. Starting profiles for B and C are also available. The choice depends on the product and production. The profile is not calibrated. Check fit, locking and protection in the target material before approving the series.
Why does the mailer have double walls?
The side walls fold inward and are held by tabs in the base. The ears sit inside them. Multiple folds change the available space and add crease allowance. The preview shows this structure but does not confirm load capacity; check that on the physical sample.
How much clearance does my product need?
There is no universal value for every product. Measure the product, insert and closure, and consider the filling workflow. The material profile changes the finished fit. A computationally valid inside dimension is therefore insufficient. Determine clearance using a sample made from the actual corrugated board.
