The 5-ply corrugated box-making machine is an automated piece of industrial equipment. It is widely used for corrugated packaging. This production line processes the corrugated paper rolls into the double-wall corrugated board. The board structure consists of the outer liner, corrugating medium, center liner, corrugating medium, and inner liner. This structure can achieve a good balance of corrugated board between thickness, strength, cushioning performance, and production cost. Because of this feature, this double-wall corrugated line is usually used for medium- and heavy-duty carton processing scenarios such as home appliances, auto parts, fresh food logistics, and export packaging.
A 5-ply automatic corrugation plant uses two single-facer machine units to produce two single-face webs independently. Then, two single-face webs are bonded with a glue machine and are used with a double-facer machine for heat setting. Eventually, this process produces the double-wall corrugated board.
First, simultaneous forming by two single-facer units
The first single-facer machine forms the corrugating medium into flutes and sticks it onto the outer liner, making the first single-face web. Meanwhile, the second single-facer machine forms the second corrugating medium into flutes and sticks it onto the center liner, making the second single-face web.
Second, overhead conveyor and preheating
The two single-face webs are transported through the bridge and preheated to ensure stable lamination.
Third, double-backer operation
The two single-faced webs are bonded, heated, and laminated in the corrugator double backer. Then it forms a complete double-wall corrugated board.
Finally, board delivery
The laminated cardboard undergoes curing, slitting, cutting, and stacking, producing the double-wall corrugated board meeting demands.
This 5-ply corrugated production line consists of many corrugator machines. All equipment works together to complete the production processes, such as the transportation of base paper, corrugated forming, lamination, drying, cutting, and stacking.

The 5-ply corrugation machine produces the double-wall corrugated board that can disperse external impact forces, improving the overall compressive strength and load-bearing performance. It is usually used for applications with heavy-duty packaging, export & transit packaging, and high-stack storage.
Heavy-Duty Packaging
This corrugated board is suitable for the packaging of products with heavy and high requirements for packaging support capacity. Examples include large household appliances, machinery, and industrial components. The board can offer excellent structural support and transportation protection.
Export & Transit Packaging
During long-distance transportation and overseas exports, the product will undergo frequent loading and unloading and vibration. The double-wall corrugated board can provide excellent cushioning protection to fit long-term storage in a container.
High-Stack Storage
Multi-layer stacked storage in the warehouse requires the corrugated board to have high ECT performance to prevent bottom-layer collapse during stacking. A 5-ply corrugated box making machine produces a double-wall corrugated board suitable for these applications. This reduces the risk of packaging deformation and enhances the stability of storage and stacking.
The 5-ply corrugated board production line is an industrial system to produce double-wall corrugated board. It is bonded with three layers of linerboard and two layers of corrugating medium, providing a high-strength solution for box packaging.
This production line supports various flute combinations, such as BC/AC/BE. It can adjust the corrugating roll based on the specific load requirements to match the needs of the pressure resistance and buffering performance.
