If you define a box as “a regular box with flaps meeting in the middle,” you are guessing. If you define it as FEFCO 0201, every packaging engineer and factory in the world knows exactly what you mean.
The FEFCO code system (European Federation of Corrugated Board Manufacturers) is the global standard for description of corrugated box instructions.
1. How the Code Works (The 4 Digits)
The code consists of four digits.
- First 2 Digits: The Style Category (Family).
- Last 2 Digits: The Specific Style Variant.
Example: 0201
- 02 = Slotted-Type Box (One piece with glued/stitched joint and top/bottom flaps).
- 01 = The specific variant where outer flaps meet in the center (Regular Slotted Container).
2. The Major Style Families
02xx: Slotted-Type Boxes (RSCs) One piece of board, glued/stitched joint. Top and bottom flaps. Ships flat.
- 0201 (RSC): Regular Slotted Container. Outer flaps meet in middle. The #1 most common box in the world. (FEFCO)
- 0203 (FOL): Full Overlap. Outer flaps overlap completely (good for double-strength top/bottom).
- 0200 (HSC): Half Slotted Container. Bottom flaps only (open top). Used with a lid.
03xx: Telescope-Type Boxes Two pieces (Lid and Bottom) that fit over each other.
- 0301: “Shoebox” style. Shallow tray/lid.
- 0310: Telescope Half Container. Lid slides over deeply. High stacking strength (double walls).
04xx: Folder-Type Boxes (Die-Cut) One piece of board that folds up around the product. Usually requires a cutting die (mold).
- 0427 (Roll End Tuck Top): The standard “Subscription Box” / “Mailer.” E-commerce favorite. Rigid and self-locking.
- 0409 (Five Panel Folder): Long wrapper for objects like golf clubs or rods. (FEFCO)
- 0422: Trays used for produce or beverage flats.
05xx: Slide-Type Boxes Sleeves and liners that slide into other boxes.
- 0501: Slide box (Drawer + Sleeve).
06xx: Rigid-Type Boxes Three pieces (two ends and a body) stitched together. Heavy industrial use.
07xx: Ready-Glued Cases (Auto-bottoms) One piece, ships flat, snaps open instantly.
- 0711 (Snap Lock): Top loaded case with pre-glued bottom.
- 0701 (Crash Lock / Auto-Bottom): Bottom folds into place automatically when you push the corners. Fast packing, higher cost.
09xx: Interior Fitments Not boxes. These are liners, pads, partitions, and dividers.
- 0901: Simple liner (Pad).
- 0933: Partition (Dividers for bottles/cells).
3. Why Designers Use FEFCO Codes
- Clarity: Removes ambiguity about flap length or glue tabs.
- Automation: CAD tables (Kongsberg/Zund) come pre-loaded with FEFCO libraries. You type “0427” and enter dimensions; the machine generates the cut file. (Esko Docs)
- Costing: Vendors can price a “0201” instantly. A “custom sketch” requires a structural designer’s time.
4. Most Common FEFCO Codes to Memorize
- 0201: Standard Shipping Case (RSC).
- 0427: E-commerce Mailer (Die-cut).
- 0203: Heavy Duty Shipper (Full Overlap).
- 0411: Five Panel Folder (Long items).
- 0933: Cell Dividers (12-pack protection).
