5 . Comparsion of the output (LDPE)

Pressure is generated if resin passes over the barrier, forcing any air in the melted resin back to the feed side and effectively preventing the intrusion of air bubbles on the sub flight side. This is highly effective with resins that generate bubbles such as PS, PA, PET and EVOH.
