Why are all top and bottom flaps the same height on a FEFCO 0201 box?

In the FEFCO 0201 standard, every top and bottom flap has an identical depth equal to half the box width (0.50 × W). This allows the entire top and bottom edges of the blank to be cut with a straight horizontal shear line, eliminating curved board waste while ensuring the two outer flaps meet flush at the center.

How wide should the slots between flaps be on corrugated cardboard?

Our kernel automatically sets the slot width to max(4.0mm, 2 × T). For 3mm B-flute board, a 6mm slot provides sufficient clearance so the adjacent inner and outer flaps do not bind or crush when folded 90 degrees.

Does the manufacturer's glue joint go inside or outside the box?

Standard FEFCO 0201 boxes fold the tapered 30–45mm glue joint tab onto the inside face of the opposite side panel using PVA cold glue or metal staples, leaving the exterior box corners smooth for case labeling.

Can I export this FEFCO 0201 dieline directly into AutoCAD or ArtiosCAD?

Yes! Clicking Export .DXF generates a clean R2000 LWPOLYLINE file with separate CUT, CREASE, and DIMENSIONS layers plus an embedded 1:1 engineering specification block.

Structural Geometry & Material Reference (FEFCO 0201 / ASSCO International Slotted Container Standard)

The FEFCO 0201 Regular Slotted Container (RSC) is the world's most widely manufactured corrugated shipping carton, accounting for over 75% of global logistics and fulfillment boxes. Its flat blank consists of four contiguous body panels (L, W, L, W) joined by a tapered manufacturer's glue joint tab, with top and bottom flaps of equal depth (H_flap = 0.50 × W) separated by vertical die-cut relief slots (W_slot = max(4mm, 2 × T)). When the outer lengthwise flaps fold inward, they meet cleanly at the center seam for H-taping.

Total Flat Blank Width (W_blank)

W_blank = 2 * L + 2 * W + Glue_Flap + 4 * T

Sums the two Length panels, two Width panels, manufacturer glue joint tab (30–45mm), and four board caliper bend allowances.

Standard RSC Top & Bottom Flap Depth (H_flap)

H_flap = 0.50 * W

Sets all four top and bottom flaps to half of the box Width (W) so the outer flaps meet edge-to-edge along the center seam.

Corrugated Flap Slot Relief Width (W_slot)

W_slot = max(4.0 mm, 2.0 * T)

Width of the vertical slots cut between adjacent flaps to prevent corrugated board crushing when folding at 90 degrees.
