Food and hospitality / JETDIELINE

Popcorn box

The popcorn box is open at the top and has four outward-sloping walls, a side seam, and a glued bottom. Length and width describe the top opening; the bottom is smaller.

How the shape is constructed

Four trapezoidal walls form a truncated pyramid. They form a fan in the flat blank. The side seam and three bottom tabs are glued. Vertical height and the shared flare angle determine the smaller bottom area and sloping wall edges.

How it is assembled

Pre-break all creases in the blank and glue the side seam to the inside of the back wall. Apply adhesive to bottom tabs, swing the bottom into place, and press the tabs against the inside of front and sides. The box then stands open and can be nested.

Material and grain direction

Grain direction parallel to height: Wall creases fold neatly and the tall walls stay stiff (check with a test print shop).

Test fit, folding and closure on a sample made from the intended material. Confirm material thickness, grain direction and production steps with your printer.

Compare openings and closures for your food product. Check direct-contact material, moisture and grease resistance with the manufacturer.

What to consider for this construction

Flare angle

Outward wall slope relative to vertical; the bottom is 2 × height × tan(angle) shorter and narrower than the opening and remains at least 30 mm wide.

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.

Frequently asked questions

Is 110 × 75 mm the bottom size?

No. In the starting example, these values describe the top inside opening. The outward-sloping walls make the bottom smaller. Height and flare angle determine the difference in both directions. If a particular footprint is required, check the calculated bottom and erected sample; opening dimensions alone are insufficient.

Why is a greater slope rejected?

The bottom must retain at least 30 mm inside dimensions on both sides. A tall box with a small opening may fall below this limit even at an angle within the parameter range. popcornFlare.bottomMinimum checks this relationship. Reduce the slope or change the opening; the individual values are not independently permissible.

How is the bottom closed?

The construction uses a glued bottom with three bottom tabs. After gluing the side seam, swing the bottom into place and press the tabs against the inside of front and sides. There is no selectable tuck bottom. Check adhesive application, assembly sequence, and bottom retention in actual board because the calculated model does not evaluate the real adhesive bond.
