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

How the shape is constructed
Circumferential length accounts for the neutral axis: π × (diameter + material thickness). Overlap is added. Top and bottom turn-ins lie outside body height. Slits divide the strips into tabs; a continuous bridge remains before the crease. Nominal tab width determines the rounded tab count.
How it is assembled
Apply glue to the starting glue area and the reverse, position the wrap’s starting edge along a generatrix, wrap tightly around the body and glue the end over the start. Pre-break the turn-ins along the creases and fold them into the tube.
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
Bottom turn-in
Strip below the bottom edge folded into the tube; disable for cans.
Turn-in depth
Turn-in width from the crease; it extends over the tube wall into its interior.
Turn-in tab width
Spacing of slits in the turn-in; tab count is rounded to fit the circumference.
Frequently asked questions
Why is the length greater than π × diameter?
Besides body diameter, the blank accounts for material thickness at the neutral axis. Glue overlap is then added. A simple rectangle of length π × diameter would omit both contributions. Compare the calculated wrap with the actual body and check seam fit on the sample.
How do I remove the turn-in for a can?
Disable the top and bottom turn-ins. The corresponding slit strips are then omitted from the blank. Body height and overlap remain input dimensions. For cardboard tubes, you can also turn in just one edge. Decide based on tube construction and check the remaining edge with the production partner.
Why is the number of turn-in tabs rounded?
The required tab width must be distributed around a closed circumference. The model therefore calculates a whole tab 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 the tabs sit inside without disruptive overlap.

Lid or base disc with tabs
The lid or base disc has glue flaps around a circular crease line. The starting dimension is the cylindrical wall's inside diameter, together with its height. The parametric dieline shows the disc as an individual component; check a matching wall and assembly separately.

Flat bag
The flat bag is formed from 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.

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