5 Ply Corrugated Cardboard Production Line
Product Description：
The high speed 5 ply corrugated cardboard production line is designed for manufacturing double-wall corrugated board, consisting of liner + medium + liner + medium + liner. Compared with 3-ply board, 5-ply corrugated board offers higher strength, better compression resistance, and improved durability, making it ideal for heavy-duty packaging and long-distance transportation. It is widely adopted by carton factories and board plants that require medium to high-grade corrugated board.
Features & Functions：
Double-wall structure: Capable of producing various flute combinations such as BC, AC, and BE flutes, ensuring both strength and smoothness.
Higher capacity: Suitable for large-scale production of strong corrugated board to meet bulk order demands.
Flexible configuration: Available in single or double facer setups, with interchangeable flute rolls.
High automation: Equipped with auto splicing, automatic web alignment, thin blade slitting, NC cutting, and stacking systems.
Stable quality: Ensures strong bonding, flat surface, and excellent performance for printing, die-cutting, and gluing.

Applications：
The 5 ply corrugated cardboard production line is mainly used by board plants and carton factories to produce heavy-duty corrugated board for demanding packaging needs.
Typical applications include:
Industrial heavy packaging: Appliances, furniture, motorcycles, bicycles, and other bulky goods.
Beverage and alcohol packaging: Beer, wine, and other transport-intensive products.
Agricultural and food transport: Fruits, vegetables, and cold-chain logistics.
Export packaging: For goods requiring high compression strength and long-distance transport protection.
E-commerce & logistics: Heavier shipment boxes for warehouse and distribution.
Compared with 3-ply board, 5-ply corrugated board provides greater stacking strength, impact resistance, and reliability, making it essential for medium to large carton production and heavy-duty export packaging.
