The 3 ply corrugated cardboard production line, also known as the 3-layer corrugated production line, is specialized automated equipment designed for manufacturing 3-ply corrugated boards (consisting of face paper, corrugated medium, and inner paper). Integrating processes such as paper feeding, heating, corrugation forming, gluing, laminating, drying, edge trimming, and paper cutting, this production line enables continuous and efficient production of high-quality 3-ply corrugated boards.
Based on customers’ production scales and market demands, the 3-ply production line is categorized into three types: ordinary type, medium-speed type, and high-speed type. It can be flexibly configured with units of different specifications to meet diverse requirements for production capacity, board quality, and automation level.

Application
The 3 ply corrugated cardboard production line is a core piece of equipment for carton factories and board plants, especially suitable for small to medium-sized packaging manufacturers. It enables stable and efficient production of 3-ply corrugated board to meet diverse packaging demands.
Board plants: For bulk production and supply of 3-ply corrugated sheets to downstream carton makers or printing & packaging companies.
Carton factories: For in-house sheet production and conversion into corrugated cartons, improving cost control and delivery efficiency.
Typical downstream applications include:
Food & beverage packaging: Frozen food, snacks, beverages, agricultural products.
Consumer goods & light industry packaging: Shoes, apparel, household items, cosmetics, toys.
E-commerce & logistics packaging: Corrugated shipping boxes for online retail and parcel delivery, suitable for light to medium-weight goods.
Electronics & small appliances packaging: Lighting, small home appliances, electronic accessories, often using B-flute or E-flute for strength and better printability.
Thanks to its lightweight structure, low cost, and recyclability, 3-ply corrugated board is widely used by board plants, carton factories, and end-user packaging sectors, making this line an ideal choice for growing packaging enterprises and e-commerce packaging suppliers.
