Flat bag
The flat bag consists of front and back with two glued side seams and a bottom fold. Enter bag width and height as outside dimensions. An optional flap on the back closes the opening; the dieline shows its effect on the paper blank.

How the shape is constructed
Front and back are arranged one above the other in the flat blank. The bottom fold connects both surfaces. Two side flaps form the glued seams; their angled ends follow the glue flap angle. The optional closure flap sits on the back. Its depth extends the blank beyond twice the bag height.
How it is assembled
Fold the side flaps inward and apply adhesive to their outside, fold the back over at the bottom fold, and press it down. After filling, fold the closure flap over the opening and glue or seal it.
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 angle
Bevel at the ends of the glue flap; facilitates folding and erection.
Closure flap
Flap at the opening edge of the back, folded over the opening onto the front.
Flap depth
Depth of the closure flap; at most half the bag height. Active when the closure flap switch is enabled.
Frequently asked questions
Are 150 × 230 mm the paper sheet dimensions?
No. They describe the width and height of the finished flat bag as outside dimensions. Front and back together require twice the height; side flaps widen the sheet and the closure flap extends it. The starting example produces a blank of 174 × 490 mm. Read the bounding box separately from the input dimensions.
How is the bottom seam formed?
Front and back remain connected at the bottom by a fold. The back is folded over after the side glue flaps have been folded inward and adhesive applied. The bag therefore has two glued side seams. This differs from a film mask with side seal zones. Check the finished bottom with the intended contents.
Can I omit the closure flap?
Yes. The bagClosureFlap switch removes the flap on the back. Flap depth belongs to this switch and requires no additional area when the flap is off. With the flap enabled, bag height limits its permissible depth. Decide before creating artwork whether the opening will remain open or be closed.

Wrap for can or tube
Calculate the wrap from diameter or circumference, height, and overlap. Slit turn-ins are added for a cardboard tube; for a can, you can disable both. The drawing shows the blank with starting values, not a finished can or confirmed fit.

Lid or base disc with tabs
The lid or base disc has glue flaps around a circular crease line. The starting dimensions are the inside diameter of the tube wall and its height. The parametric dieline shows the disc as an individual component; check a matching tube wall and assembly separately.

Gusseted bag with block bottom
The side-gusset bag has a glued longitudinal seam and a block bottom made of flaps, ears, and triangles. You set bag width, gusset depth, and height. The inside dimension shown is converted into crease-to-crease dimensions using the material profile; the flat dieline also includes the bottom overlap.
