Custom Tab Closure Standard Pillow Box Dieline Generator

A pillow box is a curved, pillow-shaped folding carton constructed from a single piece of board stock, typically featuring two opposing, arched main panels and integrated side gussets. The structure is formed by pre-creased score lines that create a shallow, convex profile when assembled. Each end of the box generally incorporates a pair of curved tuck flaps (inner and outer) that close against one another to contain the product, often with a small thumb notch for easier opening.

The blank usually includes:

• Main body panel(s): Provide the primary printable surface and define the overall length and width of the finished pack.
• Side gussets or crease lines: Allow the board to bow outward, creating the characteristic pillow shape while maintaining dimensional stability.
• End closure flaps: Curved tuck flaps that fold inward along pre-scored arcs, overlapping to create secure closures at both ends. Variants may include tab-lock or slit-lock mechanisms for enhanced retention.
• Glue or seal flap: A narrow longitudinal flap used to join the carton into its tubular form, typically adhered with cold glue or hot-melt adhesive.

Pillow boxes are commonly produced from paperboard or lightweight cardboard in grammages suitable for both direct food contact (with appropriate barrier coatings) and secondary packaging. The geometry is optimized for efficient die-cutting, low material waste, and fast manual or semi-automatic assembly. This format is frequently used for pies and other small bakery items, confectionery, gifts, and promotional products, where a compact footprint, curved presentation, and reliable end closures are required.
