Flute Profile
The designed parameter of flute is not in line with the manufacturing parameters, and the smooth finish of the roll surface is inadequate,causing a high tension of corrugating roll during the running process,that made a poor meshing and resulting in fluting paper broken.
Meijia,in accordance with the different customer needs and on-site situation, has developed special flute type,which circle parabola is adopted for the medium-high outline,solving the problems like collapsed flute,poor lamination,inner liner frothing,heavy scoring on inner liner from the very beginning.
The special flute design from Meijia:
The same meter of single corrugated board can be saved up to 5‰.
The volume of glue can be saved up to 5‰ thanks to a better lamination between fluting paper and linerboard.
