Corrugated Board Production Line: How to Choose the Right System

A corrugated board production line is the heart of any corrugated packaging operation. This guide explains how these lines work and how to select the right configuration.

What is a Corrugated Board Production Line?

A corrugated board production line (also called corrugating line or corrugator) converts paper rolls into corrugated board sheets.

Main Components

1. Mill Roll Stand - Holds and feeds paper rolls

2. Single Facer - Creates fluted medium + bonds liner

3. Bridge - Transports and buffers single-face web

4. Glue Machine - Applies adhesive to flute tips

5. Double Backer - Bonds second liner, cures adhesive

6. Slitter Scorer - Cuts to width, creates fold lines

7. Cut-Off - Cuts to sheet length

8. Stacker - Collects finished sheets

Production Line Configurations

3-Ply Line (Single Wall): 1 single facer, Light packaging applications

5-Ply Line (Double Wall): 2 single facers, Standard shipping boxes

7-Ply Line (Triple Wall): 3 single facers, Heavy-duty packaging

Speed Ratings

| Class | Design Speed | Daily Output |

| Entry | 100-150 m/min | 30,000-50,000 m² |

| Standard | 180-250 m/min | 60,000-100,000 m² |

| High-Speed | 280-350 m/min | 120,000-180,000 m² |

Traditional vs. Boiler-Free Technology

Traditional Steam Boiler Lines: Require industrial boiler, 150-180°C operation, High energy cost

Boiler-Free Lines (Xuegong Technology): No steam boiler, <100°C operation, 60% energy savings, Single facer up to 300 m/min

Key Selection Factors

1. Production Volume - Calculate required output plus 20-30% buffer

2. Product Mix - Board types, flute profiles, special requirements

3. Energy Costs - High costs favor boiler-free technology

4. Capital Budget - Boiler-free often has lower total investment
