Top turn-in
Strip above the top edge that folds into the tube; disable for cans.
Cylinders and bags / JETDIELINE
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.

Simplified display model without material thickness, not to scale.

tube.wrapThe circumferential length accounts for the neutral fiber: π × (diameter + material thickness). Overlap is added. Top and bottom turn-ins lie outside body height. Slits divide the strips into flaps; a continuous bridge remains before the crease. Nominal flap width determines the rounded flap count.
Apply glue to the starting glue area and the reverse side, position the wrap's start along a generatrix, pull it taut around the body, and glue the end over the start. Pre-break turn-ins at the creases and fold them into the tube.
Test fit, folding and closure on a sample made from the intended material. Confirm material thickness, grain direction and production steps with your printer.

These dimensions describe the preview, not a fixed packaging size. The app recalculates the dieline for your own dimensions.
Strip above the top edge that folds into the tube; disable for cans.
Strip below the bottom edge that folds into the tube; disable for cans.
Turn-in width from the crease; it extends over the tube wall into the interior.
Spacing of slits in the turn-in; flap count is rounded to fit the circumference.
In addition to body diameter, the blank accounts for material thickness at the neutral fiber. Glue overlap is then added. A simple rectangle with length π × diameter would omit both contributions. Compare the calculated wrap with the actual body and check seam fit on a sample.
Disable top turn-in and bottom turn-in. The corresponding slit strips are then removed from the blank. Body height and overlap remain input dimensions. For cardboard tubes, you can also turn in just one edge. Decide based on the tube structure and check the remaining edge with the production partner.
The desired flap width must be distributed around a closed circumference. The model therefore calculates a whole flap count and distributes the slits accordingly. Actual width may differ from the nominal value. The bridge before the crease holds the turn-in together; test whether flaps lie inside without interfering overlaps.
