Does the ABA film blower misalign

The ABA film blower combines the high hardness of PP material with the high brightness of PE material to produce films with the combination of the two characteristics. The multi-layer co-extrusion blower is also divided into several types, such as co-extrusion blower, three-layer co-extrusion blower, and seven-layer co-extrusion blower. The width is controlled by an air pump) and the width of the inserted film is measured to the standard at the same time.

If not, adjust the insert plate appropriately to qualify. Observe the symmetry of the inserted film and see if there is any misalignment. If there is any misalignment, adjust it in time. The combination of threaded sleeves is too weak to cause the extrusion screw to be too fast or the body temperature is too high or too low to cause the dispersion difference of the colour master batch. Improper selection of polyethylene (e.g. A.B.C grade PE regenerative), the melting point of material is too high or too low.

The mesh is too low when the recycled material is produced. Solution: Replace high-volume filling. Or reduce the increase of filling, set molybdenum, properly adjust the die head, body temperature, select the appropriate polyethylene resin, the die leakage screen finer. Film flatness is poor, light intensity is poor and seal is not firm. Attack elements: (flatness difference) excessive filling of color master material, (brightness difference), improper selection of carrier type and insufficient carrier, send the vesicle tube into the towing roll, and along the guide roll until winding.

After completion, quickly observe whether the bubble is deformed. If there is any deformation, adjust it in time. First check whether the gap between the die openings is adjustable and whether the bubble stabilizing plate is against the bubble. If there are no problems, check whether there are open doors and windows, and dispose of them in time. Observe whether the bubble is inclined or not. If it is inclined, stop it immediately with a baffle.
