Product Overview
The 5 Ply Corrugated cardboard Production Line, also known as a Double Wall Corrugated Board Production Line or 5 Layer Corrugated Board Production Line, is designed for continuous production of high-strength double-wall corrugated board.
A standard 5-ply corrugated board consists of three liner papers and two corrugated mediums, forming a double-wall structure that provides higher compression strength, better stacking performance, and improved protection compared with single-wall corrugated board.
This production line integrates paper feeding, preheating, corrugating, gluing, laminating, drying, slitting, cross cutting, and stacking processes into one continuous production system.
The 5 Ply Corrugated Board Production Line can be configured with different working widths, production speeds, and flute combinations according to customers’ production requirements.
It is widely used by corrugated board plants and carton manufacturers producing medium and heavy-duty packaging for industrial products, export goods, logistics transportation, and agricultural applications.
Key Features
Double-wall corrugated board production
The production line is designed for manufacturing 5-ply corrugated board with a double-wall structure, providing higher strength and load-bearing performance compared with 3-ply corrugated board.
Flexible working width options
The production line is available in different working widths from 1800 mm to 2800 mm, with larger widths up to 3300 mm available according to production requirements.
Wide production speed range
Different speed configurations are available from 100 m/min to 350 m/min to meet various production capacity requirements.
Multiple Flute Combinations
The 5 Ply Corrugated Board Production Line can be configured with different numbers of single facers to produce various flute combinations.
With two single facers, the line can produce standard double-wall corrugated boards, such as:
- BC
- AC
- BE
- AB
For customers requiring more production flexibility, the line can be equipped with three single facers to produce additional flute combinations, such as:
- ABC
- BCE
- ABE
The final configuration can be customized according to customer requirements and selected corrugating rolls.
Continuous production process
The complete line integrates paper feeding, corrugating, laminating, slitting, cutting, and stacking processes, helping manufacturers achieve stable continuous production.
Stable board quality
The production line is designed to provide stable bonding performance, good board flatness, and consistent sheet quality for further converting processes such as printing, die cutting, and box forming.
Suitable for different packaging requirements
By selecting different flute combinations and paper grades, the produced 5-ply corrugated board can meet different requirements for strength, cushioning, printing, and transportation protection.

Supported Flute Combinations
The 5 Ply Corrugated Board Production Line can produce different double-wall flute combinations according to packaging requirements.
BC Flute
BC flute combines B and C flute structures, providing good compression strength and cushioning performance.
It is commonly used for:
- Transport cartons
- Export packaging
- General industrial packaging
AC Flute
AC flute provides increased cushioning and protection performance, suitable for products requiring higher impact protection.
Applications include:
- Heavy products
- Long-distance transportation packaging
BE Flute
BE flute combines structural strength with a smoother surface suitable for printing.
It is often used for:
- Printed cartons
- Retail packaging
- Products requiring both appearance and strength
Suitable Materials
The production line can process commonly used corrugated paper materials, including:
- Kraft liner paper
- Test liner paper
- White top liner paper
- Corrugating medium paper
- Recycled paper (according to production requirements)
The paper grade selection depends on required board strength, printing requirements, and final packaging applications.
Applications
The 5 Ply Corrugated Board Production Line is widely used for producing strong corrugated sheets for medium and heavy-duty packaging.
Typical applications include:
Industrial packaging

Working Process
The production process generally includes:
1. Paper roll feeding
Paper rolls are installed on the mill roll stands and continuously supplied into the production line.
2. Paper preheating
The preheater adjusts paper moisture and temperature to improve forming and bonding performance.
3. Corrugating process
The single facer forms the corrugated medium and bonds liner paper to produce single-face corrugated board.
4. Laminating process
Glue is applied and the layers are bonded together through the double facer to form finished 5-ply corrugated board.
5. Slitting and scoring
The NC thin blade slitter scorer cuts and scores the board according to required dimensions.
6. Sheet cutting and stacking
The NC cut-off machine cuts sheets into preset lengths, and the stacker collects finished boards.
