Mailer with closure flap
Mailer with double side walls and an external closure flap. A self-adhesive strip connects the flap to the front wall; a tear strip opens it. The bottom locking tabs still hold the wall structure.

How the shape is constructed
Corrugated mailer with double side walls and ears; the lid overlaps the outside of the front wall with a closure flap sealed by a self-adhesive strip and opened with a tear strip – shipping packaging for online retail.
How it is assembled
Erect front and back walls and fold the ears inward. Erect side walls, fold the rollover with the inner wall over the ears, and insert the tabs into the bottom slots. After filling, fold in the lid dust flaps, close the lid, remove the release liner, and press the closure flap against the outside of the front wall. To open, grip the tear thread and tear out the strip.
Material and grain direction
Flute direction parallel to the blank's y-axis: The double-wall creases fold neatly, while lid hinge and tuck flap stay stiff (check with a test print shop).
Test fit, folding and closure on a sample made from the intended material. Confirm material thickness, grain direction and production steps with your printer.

What to consider for this construction
Flap gap
Gap between neighboring flaps or walls; at least approximately the material thickness.
Ear length (ratio)
Length of the ears or corner flaps as a ratio of half the inside width.
Lid dust flaps (ratio)
Length of the lid's dust flaps as a ratio of the inside height.
Dust flap angle
Bevel of the dust flaps (also the ears on the mailer); larger angles prevent collisions during folding.
Frequently asked questions
Does the front wall have locking slots?
This type does not provide slots in the front wall for the lid closure. The closure flap is glued to the outside of the wall. Bottom slots remain because they receive the double side walls' locking tabs. Do not confuse this assembly lock with the self-adhesive lid closure.
How is the flap depth limited?
closureFlapDepth begins at 30 mm and extends to 100 mm in the parameter range. The frontWall constraint additionally limits depth relative to the actual front wall. The flap needs clearance from the bottom. A value within the table range may therefore still be invalid for a low mailer.
What happens if the adhesive strip is too wide?
Adhesive strip and tear strip must fit on the same flap with clearance between them. The stripsFitClosureFlap constraint compares their dimensions with the flap depth. Adjust width, spacing, and flap together. Moving a strip after SVG export would bypass this check and does not represent a documented parameter configuration.

Book wrap
Cross-shaped wraparound packaging for books and flat goods. Additional crease lines allow folds for thinner contents; end walls and lid end flaps close the sides, and an adhesive strip closes the front.

Divider insert
Divider insert made of longitudinal and cross strips with interlocking slots to half their height. All strips lie on a shared sheet and remain connected by nicks until stripping.

Insert pad
Flat insert pad used as a base, layer, or top pad in a box. The flat dimensions follow the box's inside space; side clearance makes the pad smaller. An optional grid creates identical rounded cut-outs.

Carry box with hand hole
Corrugated carry-handle box with a snap-lock bottom. Two fully overlapping lid flaps have aligned handle cutouts and are glued over their full area; an additional handle is not part of the construction.
