Requirements of quality of flexo folder gluer machine mainly include: accurate alignment, no skew, firm adhesion, no degumming, no inner and outer lap, no scratch or obvious scratch and stain, easy to open the box, no line explosion, no corner explosion. 

(1)Requirements of quality of flexo folder gluer machine: the position of the flexo folder gluer machine interface should be aligned, especially for boxes with patterns that require docking, otherwise it will affect the appearance of the box.The height of some cartons is less than its width and length (flat type), so it’s easy to skew the paper when pasting the cartons, which makes the overlap and alignment inaccurate.

(2)Requirements of quality of flexo folder gluer machine: the adhesive is firm and does not degumm. About 12 hours after bonding, after the glue is completely dry, tear off the edge of the sticky paper, will it be considered qualified, otherwise it will prove that the bonding is not strong. Now many printing surfaces are treated by glazing, calendering, UV varnish, laminating and other processes. If the flexo folder gluer machine does not pay enough attention to this or without special treatment, it is very easy to cause the phenomenon of weak adhesion and degumming.

(3)Requirements of quality of flexo folder gluer machine: inside and outside rides. In-laying refers to: after the box is glued, the glue overflows from the paper edge of the box, causing the inside of the box to be stuck on the two sides of the box, making the box difficult or impossible to open at all. Overlaying means that after the box is glued, the glue overflows from the paper edge of the outer surface of the box, causing sticking between the box and the box, leaving traces of glue on the box surface after separation. If the outer part is serious, the printing surface will be torn apart. Therefore, both the inside and the outside will have a serious impact on the quality of the box.

(4) Requirements of quality of flexo folder gluer machine:the printed surface is scratched or left with scratches or dirt. When pasting the box automatically, due to the mechanical friction, it is easy to scratch the ink layer on the box surface, leaving scratches on the box surface. Sometimes, the ink will be dragged to the blank space, resulting in dirt. Some products are printed on the front and back, and when gluing the box, it is easy to drag the ink on the back side to the front on the front part of the box, causing dirt. In severe cases, the product can only be scrapped.
