In the production of plastic bottles, the use of color masterbatch, if the masterbatch used for plastic color mixing is uneven during the mixing in the screw, you can try the following methods.
First, when selecting masterbatch, choose a color master that is similar to the melt index of the matrix resin. Professional color master suppliers generally have special masterbatch grades for specific fields (such as blow molding). The adjustment of the processing temperature is also beneficial to the mixing of the matrix resin and the masterbatch. Of course, it is more effective to strengthen the kneading by screw recombination. A small amount of lubricant or dispersant is also beneficial to the masterbatch without affecting the formulation. The dispersion effect.
