Technology

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.
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
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
| 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 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
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
