Superior melt uniformity is required to eliminate defects like silver streaks, bubbles, and gels.
Melt temperature profile should be well controlled to improve output and film quality.
Multi-layer extrusion requires stable output and uniform film thickness. Each layer should be consistent dimensionally for defect free layer adhesion.

Barrier screw design can increase output by around 20% compared to a general single flight screw.
Shear stress is relatively low, better temperature control to avoid overheating and black spots.
A mixer is designed to improve homogeneity of melt and unmelted resin.
The feed, transition, and metering sections are well designed for screw to deliver a constant melt flow to the extrusion die to produce consistent film thickness and superior quality.
