Folding cartons and inserts / JETDIELINE

Seal-end carton

Folding carton with a side seam and glued top and bottom closures (Seal End) in place of tuck flaps: outer flap at the front, inner flap at the back, dust flaps at the sides. For pharmaceuticals and food; opened by tearing.

How the shape is constructed

The body forms four walls with a side seam. Outer flaps at the front and inner flaps at the back cover the top and bottom openings; the dust flaps lie underneath. Their overlap forms the glue strip.

How it is assembled

Pre-break the blank along all creases, glue the glue flap to the inside of the back wall, and flatten it (factory). Erect at the filling facility, fold in the bottom dust flaps and inner flap, apply adhesive to the outer flap's glue strip, and press into place; close the top the same way after filling.

Material and grain direction

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

Glue flap

Width of the glue flap used to glue the blank into a tube. The material requires a minimum width.

Glue flap angle

Bevel at the ends of the glue flap; facilitates folding and erection.

Dust flap length (ratio)

Dust flap length as a ratio of the available length.

Dust flap angle

Bevel of the dust flaps (also the ears on the mailer); larger angles prevent collisions during folding.

Dust flap relief cut

Distance between dust flap and lid along the crease; at least the material thickness. The machine requires a minimum slot width.

Frequently asked questions

What closes the seal-end carton?

An outer flap lies over an inner flap at both ends. The dust flaps are folded in first. Adhesive in the overlap strip joins the closure flaps. This construction has no tuck flap; the glued closure is torn open. The side seam is glued at the factory, and the ends are closed during filling.

How are the outer and inner flaps related?

Both depths are proportions of the opening width. The outer flap starts at 100 %, the inner flap at 60 %. Their combined overlap is decisive: it must reach at least the material's glue width. The constraint sealInnerFlap.overlap.minimumGlueFlap checks this relationship. Individually permitted parameter values do not guarantee an adequate glue strip.

Can I tuck the glued closure back in?

This template has no tuck tongue. A tuck closure that can be opened repeatedly requires a suitable tuck end carton. For the seal-end construction, plan the filling sequence and tearing open the glued end. Check adhesive application and opening with the intended board; geometry alone does not specify a guaranteed closure force.
