Rectangular base pyramid, square flaps Box Template Generator

Rectangular base pyramid, square flaps. A four-sided pyramid on a rectangular base, closed by plain square flaps that fold in and are glued rather than by a base panel. Machine erected and filled through the open base.

What is Rectangular base pyramid, square flaps?

Rectangular base pyramid, square flaps is a sleeve, wrap or slide carton. A four-sided pyramid on a rectangular base, closed by plain square flaps that fold in and are glued rather than by a base panel. Machine erected and filled through the open base.

Uses

High-volume packing lines, since a pre-glued blank erects in one movement

Advantages

Cut from a single blank, so there is one tool and one part to stock
Arrives glued and flat, and erects quickly by hand or by machine

Disadvantages

The glued joint sets the minimum order — short runs are rarely economical

Typical industries

General packing and light manufacturing

Recommended board grades

Folding boxboard or solid bleached board, typically 250–450 microns. Heavier board for larger cartons, lighter where the carton is filled by machine.

Measured against the ECMA 2022 p.51 plate with scripts/plate-diff.py. Four triangular faces round a 44.58 by 29.72 base, slants 77.57 / 77.57 / 76.43 / 77.09 / 76.48 and fan angles 33.3 / 22.2 / 33.7 / 22.3 — a true rectangular pyramid 72.5 tall. No base panel: each base edge carries a square-cornered glued flap instead, 29.72 deep off the long edges and 22.29 off the short ones, and the leading edge a tapered 11.14 glue lap. CHECK at 0.838 (cut 0.995/0.990, crease 1.000/1.000) — held there by the silhouette test. The plate's own five slant edges measure 76.43 to 77.57, a 1.5 per cent spread on a drawing that should have them all equal, so a true pyramid cannot sit inside the comparison's tolerance everywhere at once. Not promoted to verified.
