Case Study:
Blow Molded HDPE Detergent Bottle
Following a full production campaign of green bottles, a blow molder changed color to yellow by first purging using a non‐pigmented, fractional melt HDPE for two (2) to three (3) hours. After producing yellow bottles for four (4) to five (5) hours, Vitropurge® was introduced to the system. Within 15 minutes, specs and streaks of green contamination appeared, followed by a large purge of green HDPE and blow outs in the next few bottles. The superior purging and cleaning power of Vitropurge® was dramatically demonstrated.
