Demonstrating a Corrugated Board Line on Your Own Paper
A buyer's guide to requiring a corrugated board production line demonstration using the buyer's own paper, with practical checks tied to 5-layer board, 1,800 mm width and 120 m/min design speed.
Before signing off on a corrugated board production line, insist that the demonstration run on your own paper grades rather than the supplier's stock. Ask the supplier to quote a trial using your liner and fluting papers at the 5-layer configuration, and specify whether the run will use the full 1,800 mm paper width or a narrower trim.
In the request for quotation, ask how the supplier will document forming quality on your material: which board samples will be retained, how warp and bond will be checked, and whether the run will approach the 120 m/min design speed or stay below it. Clarify whether your paper is within the machine's stated working range, since catalog values such as 1,800 mm width and 120 m/min are reference figures, not guarantees for every supplied model.
For the acceptance test, agree in advance on the paper lots, the 5-layer build, sample size, and who judges results. Consider a conditional example: if your paper runs slower than the design speed without defects, is that acceptable?
Before requesting a quote, confirm with the supplier which of your paper grades they will run, what sample records the demonstration will produce, and how deviations from the reference width and speed will be reported.
