Corrugated converting equipment is designed around the type of box a manufacturer needs to produce. Two of the most common machines in corrugated plants are the Rotary Die Cutter (RDC) and Flexo Folder Gluer (FFG).
While both can combine printing and converting into an efficient production process, they serve different purposes. Understanding the difference between an RDC and an FFG can help manufacturers determine which equipment best fits their product mix and production requirements.
What Is a Rotary Die Cutter?
A Rotary Die Cutter converts corrugated sheets using a rotating die that cuts the board into specific shapes and designs.
Unlike standard slotted boxes, many die-cut packages require specialized cuts, openings, handles, ventilation holes, or unique structural features. Rotary die cutting provides the flexibility and precision needed to produce these more complex designs at production speeds.
A modern RDC can combine several processes into one production line, including:
- Feeding
- Flexographic printing
- Die cutting
- Waste removal
- Stacking
Accurate sheet control and print-to-cut registration are especially important because the printed graphics and die-cut pattern must remain properly aligned throughout production.
RDCs are commonly used for displays, trays, specialty packaging, produce boxes, retail packaging, and other die-cut corrugated products.
What Is a Flexo Folder Gluer?
A Flexo Folder Gluer combines multiple converting processes to transform corrugated sheets into finished folded and glued boxes.
Depending on the machine configuration, an FFG can perform:
- Feeding
- Flexographic printing
- Slotting and scoring
- Die cutting
- Folding
- Gluing
- Counting and stacking
By completing these processes in a continuous production line, an FFG can efficiently produce large quantities of finished boxes with minimal additional handling.
FFGs are particularly well suited for producing regular slotted containers (RSCs) and other folded and glued corrugated boxes.
RDC vs. FFG: The Main Difference
The biggest difference is what happens to the sheet during the converting process.
An RDC focuses on precision die cutting, making it ideal for corrugated products that require custom shapes or more complex structural designs.
An FFG focuses on producing folded and glued boxes, combining printing, slotting, folding, and gluing into a continuous process.
Put simply:
RDC = Print + Die Cut
FFG = Print + Convert + Fold + Glue
Both technologies can provide high-speed production, precise registration, automation, and repeatable quality. The right choice depends on the type of boxes your operation produces.
Which Machine Is Right for Your Operation?
Choosing between an RDC and an FFG starts with understanding your current and future product mix.
An RDC may be the better fit when your operation produces a significant volume of specialty or die-cut packaging requiring complex shapes and precise cutting.
An FFG may be the better fit when your operation needs efficient, high-volume production of folded and glued boxes.
For many corrugated plants, the answer isn't necessarily one or the other. Having both technologies can provide the flexibility to produce a broader range of corrugated packaging and respond to changing customer requirements.
Finding the Right Converting Solution
The right equipment should support more than today's production schedule. Machine format, board requirements, box styles, automation, changeover requirements, production volume, and future growth should all be considered when evaluating converting equipment.
