Tapered octagonal carton, panel lid and base Box Template Generator

Tapered octagonal carton, panel lid and base. Eight tapered sides closed by a full octagon top and bottom — the flower-pot shape, close to a cone while still folding flat. Used for confectionery and hamper packaging.

Checked against the plate. This blank has been compared side by side with the drawing in the FEFCO Code, 12th Edition, and matches. That is a statement about the drawing, not a guarantee — always cut and fold a sample before committing to a die.
