Corrugated box styles by FEFCO code

A box style is the shape of the blank and how it folds. The international case code gives each design a four-digit number; US practice adds names such as RSC and FOL. Packgent draws every style below from its own rule, so each drawing redraws at your size.

Styles by series

02 series: Slotted boxes

Code	Name	Short form
0200	Half slotted container	HSC
0201	Regular slotted container	RSC
0202	Overlap slotted container	OSC
0203	Full overlap slotted container	FOL
0204	Center special slotted container	CSSC
0205	Center special overlap slotted container	CSO
0206	Center special full overlap container	SFF

03 series: Telescope boxes

Code	Name	Short form
0301	Full telescope design style container	FTD

04 series: Folders and wraps

Code	Name	Short form
0406	Wrap-around blank	—
0410	Five panel folder	FPF
0427	Roll end tray with locking cover	—

06 series: Rigid (Bliss) boxes

The 06 series covers three-piece boxes: two end panels joined to a body that forms the sides, bottom and top. The FBA notes the code calls these rigid-type boxes, because the box is rigid once its six or more joints are sealed.

07 series: Ready-glued boxes

Code	Name	Short form
0711	Pre-glued auto bottom with RSC top flaps	—
0714	Telescope box from two self-erecting pieces	—

09 series: Interior fittings

The 09 series covers the parts that go inside a box: pads, liners, dividers and partitions. The FBA notes that partitions give each item its own cell and are used mostly for glassware and other fragile goods.

Board use across the slotted family

Same inside size, 12 × 10 × 8 in, nominal blank without score allowances. The flap rule alone decides how much board each style takes.

Style	Blank length, in	Blank width, in	Area, ft²	vs RSC
0200 HSC	45.25	13	4.09	-28%
0201 RSC	45.25	18	5.66	0%
0202 OSC	45.25	19	5.97	6%
0203 FOL	45.25	28	8.8	56%
0204 CSSC	45.25	20	6.28	11%
0205 CSO	45.25	20	6.28	11%
0206 SFF	45.25	28	8.8	56%
