2019-09-19

The issue of the face paper delaminating on a five-layer corrugated cardboard production line is something that many corrugated cardboard manufacturers may encounter. So what should be done when the corrugated cardboard production line faces such problems?Qingdao Yesheng Packaging MachineryLet me give you some advice:

① First, check whether the delamination is occurring on both sides of the cardboard or in the middle. If one side is delaminating, check whether the glue amount on the gluing machine is too small and whether the side pressure of the corrugating roller is too low. If it is in the middle, check whether the tension of the face paper is too low and whether the pressure of the corrugating roller is too low. If so, adjust them to be parallel.

② If none of the above reasons apply, check whether the rollers of the single-sided corrugating machines are concave and whether there is a concave in the middle of the double-sided machine's preheating plate.

Production line, opening glue, whether too small, check, middle, corrugated cardboard, corrugation, problem.
