# What are the Different Types of Flexo Folder Gluer Machines?

Introduction to Flexo Folder Gluer Machines

Flexo Folder Gluer Machines are essential tools in the corrugated packaging industry. They combine high-quality flexographic printing, precise slotting and die-cutting, and efficient folding and gluing all in one streamlined process. This integration makes them indispensable for businesses aiming to produce custom corrugated boxes that meet modern demands for branding, durability, and cost-effectiveness. At Keshenglong, a leader in carton printing machinery since 1995, we know how crucial it is to choose the right Flexo Folder Gluer Machine for your production line. Understanding the different types available will ensure you select the best solution tailored to your business.

What is a Flexo Folder Gluer Machine?

A Flexo Folder Gluer Machine (FFG) is an advanced piece of equipment designed for the high-speed manufacture of corrugated carton boxes. It handles several vital steps: flexographic printing, slotting, die-cutting, folding, and gluing—allowing for a fully automatic and seamless workflow. These machines are ideal for large-scale production, maintaining precision and consistency throughout long runs.

Classification Based on Automation Level

Semi-Automatic Flexo Folder Gluer Machines

Semi-automatic FFGs require certain manual interventions, such as feeding the sheets or stacking finished cartons. These machines are highly suitable for small to medium-volume manufacturers or businesses with diverse order requirements. They offer flexibility with a lower initial investment, making them accessible for packaging plants upgrading from manual processes.

Fully Automatic Flexo Folder Gluer Machines

Fully automatic Flexo Folder Gluer Machines automate all production steps, from sheet feeding to stacking finished cartons. With integrated computer controls and servo-driven systems, they can achieve high speeds and exceptional accuracy while reducing labor costs. For high-volume or continuous production, especially in industries like e-commerce, automotive, and food packaging, these automatic solutions from Keshenglong are indispensable.

Classification by Number of Print Units/Colors

Single-Color Flexo Folder Gluer Machines

Single-color FFGs feature one printing unit, suitable for straightforward branding or where color requirements are minimal. They are popular in markets where plain cartons or simple logos suffice.

Multi-Color Flexo Folder Gluer Machines (Up to 6+1 Color)

For customers seeking vibrant, detailed graphics, multi-color machines are the best choice. Keshenglong offers options ranging from two to 6+1 color stations, supporting high-impact retail and branded packaging needs. Multi-color stations bring flexibility in design, enabling photo-quality prints and complex artwork on corrugated boxes.

Classification by Die-Cutting Capabilities

Slotting and Creasing Machines

Some FFGs focus primarily on slotting and creasing functions, making precise cuts and fold lines to form standard boxes. Simple slotting models are excellent for manufacturers who do not need custom-shaped packaging.

Rotary Die-Cutting Folder Gluer Machines

Machines with rotary die-cutting capabilities expand design possibilities, allowing for intricate shapes and specialized packaging structures. These high-precision FFGs are ideal for brands looking to differentiate their cartons with custom windows, handles, or contoured cut-outs.

Classification by Print Positioning

Top-Printing Flexo Folder Gluer Machines

Top-printing FFGs apply print to the upper surface of the corrugated sheet before folding. They are typically used when graphics are needed outside the box. Keshenglong’s top-printing slotter die-cutters deliver superior registration and color consistency.

Bottom-Printing Flexo Folder Gluer Machines

These machines print on the bottom side of the sheet, suitable for specific structural designs or where branding on the inside of the box is desired.

Top & Bottom-Printing Flexo Folder Gluer Machines

Combining both positions, these machines offer unmatched flexibility for complex or dual-sided print jobs. Keshenglong’s dual-position models enable simultaneous printing on both sides, optimizing productivity and creative potential.

Classification by Handling Capacity

Standard-Sized Flexo Folder Gluer Machines

Standard-sized FFGs handle popular corrugated sheet dimensions, perfect for packaging applications with typical box sizes. Most small-to-mid-size manufacturing facilities utilize these models for volume production of shipping and display cartons.

Jumbo Flexo Folder Gluer Machines

Jumbo FFGs are engineered for processing extra-large sheets, ideal for industries requiring oversized packaging or protective carton solutions. These robust machines can manage heavy, dense materials and deliver consistent quality for large-format boxes.

Intelligent and Computerized Flexo Folder Gluer Solutions

Computerized High-Speed Flexo Folder Gluer Machines

Equipped with PLC touch-screens, servo motors, and sensor-based quality control systems, computerized FFGs offer rapid job changeovers, reduced setup times, and enhanced automation. They enable data tracking, remote diagnostics, and seamless integration into Industry 4.0-ready smart factories. Our Keshenglong high-speed computerized case makers embody these advancements, supporting both output efficiency and quality assurance.

Integrated Case Makers

Modern FFGs can be combined with auxiliary equipment such as automatic stackers, inline quality inspection systems, and modular printing stations for complete packaging lines. Keshenglong offers fully integrated packaging solutions designed for high-volume, multi-format carton production.
