从China供应商批发进口3/5-Layer Corrugated Paperboard Production Line — FOB条款

Hangzhou Royal Packing Machinery Co. Ltd. manufactures complete corrugated paperboard production lines with 3-layer and 5-layer configurations from its base in Hangzhou, Zhejiang Province. The line integrates mill roll stands, single facers, pre-heaters, conveyor bridges, gluing machines, slitter-scorer units, cut-off machines, and stackers into a continuous production system. Working widths range from 1400 mm to 2500 mm, with design speeds from 60 to 250 metres per minute, though achievable sustained speed depends on flute profile, paper grade, and operator skill. The supplier also offers seven-layer configurations and individual line components for buyers upgrading existing installations.

The corrugating process heats and conditions linerboard and fluting paper through pre-heaters and single facers before starch-based adhesive application on the double backer. Three-ply construction produces single-wall board with one fluted medium between two liners; five-ply construction produces double-wall board with two fluted layers and three liners. Typical flute profiles include A-flute (4.8 mm height), C-flute (3.6 mm), B-flute (2.5 mm), E-flute (1.2 mm), and combinations such as BC or AC for specific stacking and printability requirements. The source does not specify corrugating roll diameter, tungsten carbide coating, or vacuum fingerless single-facer technology; confirm these for high-speed operation above 200 m/min.

Buyers include carton converters, integrated packaging manufacturers, and corrugated board plants serving food, beverage, electronics, and consumer goods sectors. The modular design allows customisation to existing plant layouts, though foundation drawings, steam consumption, and electrical load profiles are not stated and must be requested. Individual components can be supplied for line completion or modernisation projects. No MOQ, price band, or standard lead time is available in the source data; negotiate these directly with Hangzhou Royal Packing Machinery for your specific width and speed requirement.
