Product Overview
The 3 Ply Corrugated Cardboard Production Line, also known as a 3 Layer Corrugated Board Production Line or Single Wall Corrugator Line, is designed for the continuous production of 3-ply corrugated board.
A standard 3-ply corrugated board consists of one outer liner, one corrugated medium, and one inner liner. It is widely used for manufacturing corrugated cartons for food, beverages, consumer goods, e-commerce packaging, and many other applications.
The production line integrates paper feeding, preheating, corrugating, gluing, laminating, drying, slitting, cross cutting, and stacking into one continuous process. Different configurations are available to meet various production capacities, board specifications, and automation requirements.
According to production speed and customer requirements, the line can be configured as ordinary, medium-speed, or high-speed models with working widths ranging from 1400 mm to 2500 mm.
Key Features
- The production line is designed for continuous manufacturing of 3-ply corrugated board, helping improve production efficiency and maintain stable board quality.
- Working widths from 1400 mm to 2500 mm are available to suit different production requirements and factory layouts.
- The line can be configured as ordinary, medium-speed, or high-speed models depending on the required production capacity.
- The production line can produce various flute types, including A, B, C, and E flute, depending on the selected corrugating rolls.
- Each production line can be configured according to customer requirements, including different paper stands, single facers, heating systems, slitter scorers, cut-off machines, and stackers.
- The production process can be controlled through an integrated control system, helping coordinate each section of the production line.
- The conveying system transports corrugated board smoothly between different production sections to maintain stable operation.
- The line is designed for continuous production under normal operating conditions, making it suitable for board plants and carton manufacturers.

A Flute
Provides good cushioning performance and is commonly used for protective packaging.
B Flute
Offers a relatively flat surface and is suitable for cartons requiring good printing quality.
C Flute
Balances compression strength and cushioning performance, making it one of the most commonly used flute types.
E Flute
Features a thinner profile and is often used for retail packaging, printed cartons, and lightweight packaging.
Suitable Materials
The production line is suitable for processing various paper grades used in corrugated board manufacturing, including:
- Kraft liner paper
- Test liner
- White top liner
- Corrugating medium paper
- Recycled paper (depending on production requirements)
Paper specifications should be selected according to the required board strength and product application.

The actual board specification should be selected according to the required product strength and transportation conditions.
Working Process
The production process typically includes the following steps:
- Paper rolls are loaded onto the mill roll stand.
- The liner paper and medium paper are preheated.
- The single facer forms the corrugated flute and bonds the first liner.
- The board passes through the bridge conveyor.
- Adhesive is applied before laminating.
- The double facer bonds the second liner to produce 3-ply corrugated board.
- The board is slit and scored to the required dimensions.
- The NC cut-off machine cuts the board into preset sheet lengths.
- Finished sheets are stacked for the next converting process.
