The single facer corrugation machine is the core of corrugated board production. It is responsible for producing the corrugated layer required for each carton and plays a vital role in the corrugated packaging industry. Choosing a suitable single-face corrugator can significantly improve production efficiency and cardboard quality.
What Is a Single Facer Corrugated Machine?
A single facer machine combines a corrugated medium and liner paper using heat, pressure, and adhesive to form single-faced corrugated board — the base for most packaging boxes.
It streamlines the corrugation process and ensures consistent production of durable packaging materials.
How Does a Single Facer Work?
Single facer machines form flutes from kraft paper and bond them with liner paper. Here’s how:
Key Steps in Operation
- Raw Material Feeding: Kraft paper rolls serve as fluting and liner paper.
- Corrugation Formation: Heated rolls shape the fluting medium.
- Adhesive Application: Glue is applied to flute tips.
- Bonding and Heating: Liner is bonded to the flutes with heat.
| Process Step | Function | Output |
|---|---|---|
| Raw Material Feeding | Supplies kraft paper | Paper rolls |
| Corrugation Formation | Forms flutes in the medium | Corrugated medium |
| Adhesive Application | Applies glue | Prepared medium |
| Bonding and Heating | Bonds liner and flute with heat | Single-faced board |
What Types of Single Facer Machines Are There?
- Cassette Type
Designed for fast flute change, this modular machine allows quick replacement of corrugating rolls in under 10 minutes. Ideal for production lines requiring frequent flute profile changes. - Standard Type
Traditional fixed-roll configuration, suitable for stable, continuous production. Based on structural layout, it includes:- Inclined Type
Features a tilted frame design, improving operator access and paper feeding angle. Common in compact production environments.
Example: SF280 Fingerless Single Facer - Fixed Type
Horizontal structure with a rigid chassis, designed for high stability during long-run production. Easy to maintain and operate under consistent settings.
- Inclined Type
Why Are Single Facer Machines Important?
They are essential for producing high-volume corrugated packaging, reducing labor and improving board quality.
Key Benefits
- Efficiency: Up to 350m/min high-speed production
- Durability: Strong bonding ensures board strength
- Versatility: Supports various flute profiles (A, B, C, etc.)
- Eco-Friendly: Works with recyclable materials
Key Components of a Single Facer
Understanding each part helps in maintenance and efficient operation.
- Corrugating Rolls: Shapes paper into flutes
- Pressure Rolls: Press liner onto flute tips
- Glue Unit: Applies precise glue lines
- Heating System: Heats paper and glue for bonding
| Component | Function |
|---|---|
| Corrugating Rolls | Forms the fluted shape |
| Pressure Rolls | Bonds flute tips and liner |
| Glue Unit | Applies adhesive |
| Heating System | Ensures strong adhesion |
Production Capacity & Applications
Typical capacity: 60–350 m/min. Ideal for medium to big manufacturers.
Applications:
- Single or double-wall corrugated cardboard
- Box liners

Common Problems and Solutions
- Flute Misformation → Check roll wear and pressure settings
- Delamination → Inspect glue temperature and pressure
- Uneven feeding → Align paper rolls and correct tension
How to Maintain a Single Facer Corrugation Machine
- Daily cleaning of dust and glue residue
- Lubricate moving parts and check roll temperatures
- Monthly alignment check for bearings and gears
- Replace worn corrugating rolls when needed
How to Choose the Right Machine
- Required speed and output volume
- Desired flute profile (A/B/C/E/F)
- Heating method (steam/oil/electric)
- Ease of maintenance and part replacement
- After-sales service & spare parts availability
Single Facer Machine Price Range
Typically $20,000 to $120,000 depending on:
- Automation level
- Corrugating roll change system
- Speed and width
- Heating system type
