White Swirls

[PVCSKI]

How can i make white marbley, swirls in PP cases, with in house PE based colors. I know low B. Pressure works but with what colors? Any colors ok

You might consider a miss-match in melt flow. Chose a low MI concentrate and a medium to high MF resin should enhance marbling. Also, mix color concetrates; different shades of the same or nearly the same color added into your resin.
